To access a local +source snapshot or unreleased branch, use Podfile directives like the following: + +To access FirebaseFirestore via a branch: +```ruby +pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' +pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' +``` + +To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do: + +```ruby +pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk' +pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk' +``` + +### Carthage (iOS only) + +Instructions for the experimental Carthage distribution are at +[Carthage](Carthage.md). + +### Using Firebase from a Framework or a library + +[Using Firebase from a Framework or a library](docs/firebase_in_libraries.md) + +## Development + +To develop Firebase software in this repository, ensure that you have at least +the following software: + + * Xcode 12.2 (or later) + +CocoaPods is still the canonical way to develop, but much of the repo now supports +development with Swift Package Manager. + +### CocoaPods + +Install + * CocoaPods 1.10.0 (or later) + * [CocoaPods generate](https://github.com/square/cocoapods-generate) + +For the pod that you want to develop: + +```ruby +pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios +``` + +Note: If the CocoaPods cache is out of date, you may need to run +`pod repo update` before the `pod gen` command. + +Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for +those platforms. Since 10.2, Xcode does not properly handle multi-platform +CocoaPods workspaces. + +Firestore has a self contained Xcode project. See +[Firestore/README.md](Firestore/README.md). + +#### Development for Catalyst +* `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios` +* Check the Mac box in the App-iOS Build Settings +* Sign the App in the Settings Signing & Capabilities tab +* Click Pods in the Project Manager +* Add Signing to the iOS host app and unit test targets +* Select the Unit-unit scheme +* Run it to build and test + +Alternatively disable signing in each target: +* Go to Build Settings tab +* Click `+` +* Select `Add User-Defined Setting` +* Add `CODE_SIGNING_REQUIRED` setting with a value of `NO` + +### Swift Package Manager +* To enable test schemes: `./scripts/setup_spm_tests.sh` +* `open Package.swift` or double click `Package.swift` in Finder. +* Xcode will open the project + * Choose a scheme for a library to build or test suite to run + * Choose a target platform by selecting the run destination along with the scheme + +### Adding a New Firebase Pod + +See [AddNewPod.md](AddNewPod.md). + +### Managing Headers and Imports + +See [HeadersImports.md](HeadersImports.md). + +### Code Formatting + +To ensure that the code is formatted consistently, run the script +[./scripts/check.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/check.sh) +before creating a PR. + +GitHub Actions will verify that any code changes are done in a style compliant +way. Install `clang-format` and `mint`: + +```console +brew install clang-format@13 +brew install mint +``` + +### Running Unit Tests + +Select a scheme and press Command-u to build a component and run its unit tests. + +### Running Sample Apps +In order to run the sample apps and integration tests, you'll need a valid +`GoogleService-Info.plist` file. The Firebase Xcode project contains dummy plist +files without real values, but can be replaced with real plist files. To get your own +`GoogleService-Info.plist` files: + +1. Go to the [Firebase Console](https://console.firebase.google.com/) +2. Create a new Firebase project, if you don't already have one +3. For each sample app you want to test, create a new Firebase app with the sample app's bundle +identifier (e.g. `com.google.Database-Example`) +4. Download the resulting `GoogleService-Info.plist` and add it to the Xcode project. + +### Coverage Report Generation + +See [scripts/code_coverage_report/README.md](scripts/code_coverage_report/README.md). + +## Specific Component Instructions +See the sections below for any special instructions for those components. + +### Firebase Auth + +If you're doing specific Firebase Auth development, see +[the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about +building and running the FirebaseAuth pod along with various samples and tests. + +### Firebase Database + +The Firebase Database Integration tests can be run against a locally running Database Emulator +or against a production instance. + +To run against a local emulator instance, invoke `./scripts/run_database_emulator.sh start` before +running the integration test. + +To run against a production instance, provide a valid GoogleServices-Info.plist and copy it to +`FirebaseDatabase/Tests/Resources/GoogleService-Info.plist`. Your Security Rule must be set to +[public](https://firebase.google.com/docs/database/security/quickstart) while your tests are +running. + +### Firebase Performance Monitoring +If you're doing specific Firebase Performance Monitoring development, see +[the Performance README](FirebasePerformance/README.md) for instructions about building the SDK +and [the Performance TestApp README](FirebasePerformance/Tests/TestApp/README.md) for instructions about +integrating Performance with the dev test App. + +### Firebase Storage + +To run the Storage Integration tests, follow the instructions in +[FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m). + +#### Push Notifications + +Push notifications can only be delivered to specially provisioned App IDs in the developer portal. +In order to actually test receiving push notifications, you will need to: + +1. Change the bundle identifier of the sample app to something you own in your Apple Developer +account, and enable that App ID for push notifications. +2. You'll also need to +[upload your APNs Provider Authentication Key or certificate to the +Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs) +at **Project Settings > Cloud Messaging > [Your Firebase App]**. +3. Ensure your iOS device is added to your Apple Developer portal as a test device. + +#### iOS Simulator + +The iOS Simulator cannot register for remote notifications, and will not receive push notifications. +In order to receive push notifications, you'll have to follow the steps above and run the app on a +physical device. + +## Building with Firebase on Apple platforms + +Firebase 8.9.0 introduces official beta support for macOS, Catalyst, and tvOS. watchOS continues +to be community supported. Thanks to community contributions for many of the multi-platform PRs. + +At this time, most of Firebase's products are available across Apple platforms. There are still +a few gaps, especially on watchOS. For details about the current support matrix, see +[this chart](https://firebase.google.com/docs/ios/learn-more#firebase_library_support_by_platform) +in Firebase's documentation. + +### watchOS +Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and +work on watchOS. See the [Independent Watch App Sample](Example/watchOSSample). + +Keep in mind that watchOS is not officially supported by Firebase. While we can catch basic unit +test issues with GitHub Actions, there may be some changes where the SDK no longer works as expected +on watchOS. If you encounter this, please +[file an issue](https://github.com/firebase/firebase-ios-sdk/issues). + +During app setup in the console, you may get to a step that mentions something like "Checking if the +app has communicated with our servers". This relies on Analytics and will not work on watchOS. +**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected. + +#### Additional Crashlytics Notes +* watchOS has limited support. Due to watchOS restrictions, mach exceptions and signal crashes are +not recorded. (Crashes in SwiftUI are generated as mach exceptions, so will not be recorded) + +## Combine +Thanks to contributions from the community, _FirebaseCombineSwift_ contains support for Apple's Combine +framework. This module is currently under development, and not yet supported for use in production +environments. Fore more details, please refer to the [docs](FirebaseCombineSwift/README.md). + +## Roadmap + +See [Roadmap](ROADMAP.md) for more about the Firebase Apple SDK Open Source +plans and directions. + +## Contributing + +See [Contributing](CONTRIBUTING.md) for more information on contributing to the Firebase +Apple SDK. + +## License + +The contents of this repository are licensed under the +[Apache License, version 2.0](http://www.apache.org/licenses/LICENSE-2.0). + +Your use of Firebase is governed by the +[Terms of Service for Firebase Services](https://firebase.google.com/terms/). + +[gh-actions]: https://github.com/firebase/firebase-ios-sdk/actions +[gh-abtesting-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/abtesting/badge.svg +[gh-appcheck-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/app_check/badge.svg +[gh-appdistribution-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/appdistribution/badge.svg +[gh-auth-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/auth/badge.svg +[gh-cocoapods-integration-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/cocoapods-integration/badge.svg +[gh-core-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/core/badge.svg +[gh-core-diagnostics-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/core-diagnostics/badge.svg +[gh-crashlytics-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/crashlytics/badge.svg +[gh-database-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/database/badge.svg +[gh-datatransport-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/datatransport/badge.svg +[gh-dynamiclinks-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/dynamiclinks/badge.svg +[gh-firebasepod-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/firebasepod/badge.svg +[gh-firestore-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/firestore/badge.svg +[gh-functions-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/functions/badge.svg +[gh-google-utilities-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/google-utilities/badge.svg +[gh-google-utilities-components-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/google-utilities-components/badge.svg +[gh-inappmessaging-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/inappmessaging/badge.svg +[gh-interop-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/interop/badge.svg +[gh-messaging-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/messaging/badge.svg +[gh-mlmodeldownloader-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/mlmodeldownloader/badge.svg +[gh-performance-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/performance/badge.svg +[gh-remoteconfig-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/remoteconfig/badge.svg +[gh-storage-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/storage/badge.svg +[gh-symbolcollision-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/symbolcollision/badge.svg +[gh-zip-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/zip/badge.svg diff --git a/saraWhatsUp/Pods/FirebaseAuth/FirebaseAuth/CHANGELOG.md b/saraWhatsUp/Pods/FirebaseAuth/FirebaseAuth/CHANGELOG.md new file mode 100644 index 0000000..4a0bbf3 --- /dev/null +++ b/saraWhatsUp/Pods/FirebaseAuth/FirebaseAuth/CHANGELOG.md @@ -0,0 +1,315 @@ +# 8.9.0 +- [changed] Improved error logging.

To access a local +source snapshot or unreleased branch, use Podfile directives like the following: + +To access FirebaseFirestore via a branch: +```ruby +pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' +pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' +``` + +To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do: + +```ruby +pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk' +pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk' +``` + +### Carthage (iOS only) + +Instructions for the experimental Carthage distribution are at +[Carthage](Carthage.md). + +### Using Firebase from a Framework or a library + +[Using Firebase from a Framework or a library](docs/firebase_in_libraries.md) + +## Development + +To develop Firebase software in this repository, ensure that you have at least +the following software: + + * Xcode 12.2 (or later) + +CocoaPods is still the canonical way to develop, but much of the repo now supports +development with Swift Package Manager. + +### CocoaPods + +Install + * CocoaPods 1.10.0 (or later) + * [CocoaPods generate](https://github.com/square/cocoapods-generate) + +For the pod that you want to develop: + +```ruby +pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios +``` + +Note: If the CocoaPods cache is out of date, you may need to run +`pod repo update` before the `pod gen` command. + +Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for +those platforms. Since 10.2, Xcode does not properly handle multi-platform +CocoaPods workspaces. + +Firestore has a self contained Xcode project.

Install `clang-format` and `mint`: + +```console +brew install clang-format@13 +brew install mint +``` + +### Running Unit Tests + +Select a scheme and press Command-u to build a component and run its unit tests. + +### Running Sample Apps +In order to run the sample apps and integration tests, you'll need a valid +`GoogleService-Info.plist` file. The Firebase Xcode project contains dummy plist +files without real values, but can be replaced with real plist files. To get your own +`GoogleService-Info.plist` files: + +1. Go to the [Firebase Console](https://console.firebase.google.com/) +2. Create a new Firebase project, if you don't already have one +3. For each sample app you want to test, create a new Firebase app with the sample app's bundle +identifier (e.g. `com.google.Database-Example`) +4. Download the resulting `GoogleService-Info.plist` and add it to the Xcode project. + +### Coverage Report Generation + +See [scripts/code_coverage_report/README.md](scripts/code_coverage_report/README.md). + +## Specific Component Instructions +See the sections below for any special instructions for those components. + +### Firebase Auth + +If you're doing specific Firebase Auth development, see +[the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about +building and running the FirebaseAuth pod along with various samples and tests. + +### Firebase Database + +The Firebase Database Integration tests can be run against a locally running Database Emulator +or against a production instance. + +To run against a local emulator instance, invoke `./scripts/run_database_emulator.sh start` before +running the integration test. + +To run against a production instance, provide a valid GoogleServices-Info.plist and copy it to +`FirebaseDatabase/Tests/Resources/GoogleService-Info.plist`. Your Security Rule must be set to +[public](https://firebase.google.com/docs/database/security/quickstart) while your tests are +running. + +### Firebase Performance Monitoring +If you're doing specific Firebase Performance Monitoring development, see +[the Performance README](FirebasePerformance/README.md) for instructions about building the SDK +and [the Performance TestApp README](FirebasePerformance/Tests/TestApp/README.md) for instructions about +integrating Performance with the dev test App. + +### Firebase Storage + +To run the Storage Integration tests, follow the instructions in +[FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m). + +#### Push Notifications + +Push notifications can only be delivered to specially provisioned App IDs in the developer portal. +In order to actually test receiving push notifications, you will need to: + +1. Change the bundle identifier of the sample app to something you own in your Apple Developer +account, and enable that App ID for push notifications. +2. You'll also need to +[upload your APNs Provider Authentication Key or certificate to the +Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs) +at **Project Settings > Cloud Messaging > [Your Firebase App]**. +3. Ensure your iOS device is added to your Apple Developer portal as a test device. + +#### iOS Simulator + +The iOS Simulator cannot register for remote notifications, and will not receive push notifications. +In order to receive push notifications, you'll have to follow the steps above and run the app on a +physical device. + +## Building with Firebase on Apple platforms + +Firebase 8.9.0 introduces official beta support for macOS, Catalyst, and tvOS. watchOS continues +to be community supported. Thanks to community contributions for many of the multi-platform PRs. + +At this time, most of Firebase's products are available across Apple platforms. There are still +a few gaps, especially on watchOS. For details about the current support matrix, see +[this chart](https://firebase.google.com/docs/ios/learn-more#firebase_library_support_by_platform) +in Firebase's documentation. + +### watchOS +Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and +work on watchOS. See the [Independent Watch App Sample](Example/watchOSSample). + +Keep in mind that watchOS is not officially supported by Firebase. While we can catch basic unit +test issues with GitHub Actions, there may be some changes where the SDK no longer works as expected +on watchOS. If you encounter this, please +[file an issue](https://github.com/firebase/firebase-ios-sdk/issues). + +During app setup in the console, you may get to a step that mentions something like "Checking if the +app has communicated with our servers". This relies on Analytics and will not work on watchOS. +**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected. + +#### Additional Crashlytics Notes +* watchOS has limited support. Due to watchOS restrictions, mach exceptions and signal crashes are +not recorded. (Crashes in SwiftUI are generated as mach exceptions, so will not be recorded) + +## Combine +Thanks to contributions from the community, _FirebaseCombineSwift_ contains support for Apple's Combine +framework. This module is currently under development, and not yet supported for use in production +environments. Fore more details, please refer to the [docs](FirebaseCombineSwift/README.md). + +## Roadmap + +See [Roadmap](ROADMAP.md) for more about the Firebase Apple SDK Open Source +plans and directions. + +## Contributing + +See [Contributing](CONTRIBUTING.md) for more information on contributing to the Firebase +Apple SDK. + +## License + +The contents of this repository are licensed under the +[Apache License, version 2.0](http://www.apache.org/licenses/LICENSE-2.0). + +Your use of Firebase is governed by the +[Terms of Service for Firebase Services](https://firebase.google.com/terms/). + +[gh-actions]: https://github.com/firebase/firebase-ios-sdk/actions +[gh-abtesting-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/abtesting/badge.svg +[gh-appcheck-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/app_check/badge.svg +[gh-appdistribution-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/appdistribution/badge.svg +[gh-auth-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/auth/badge.svg +[gh-cocoapods-integration-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/cocoapods-integration/badge.svg +[gh-core-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/core/badge.svg +[gh-core-diagnostics-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/core-diagnostics/badge.svg +[gh-crashlytics-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/crashlytics/badge.svg +[gh-database-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/database/badge.svg +[gh-datatransport-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/datatransport/badge.svg +[gh-dynamiclinks-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/dynamiclinks/badge.svg +[gh-firebasepod-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/firebasepod/badge.svg +[gh-firestore-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/firestore/badge.svg +[gh-functions-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/functions/badge.svg +[gh-google-utilities-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/google-utilities/badge.svg +[gh-google-utilities-components-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/google-utilities-components/badge.svg +[gh-inappmessaging-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/inappmessaging/badge.svg +[gh-interop-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/interop/badge.svg +[gh-messaging-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/messaging/badge.svg +[gh-mlmodeldownloader-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/mlmodeldownloader/badge.svg +[gh-performance-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/performance/badge.svg +[gh-remoteconfig-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/remoteconfig/badge.svg +[gh-storage-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/storage/badge.svg +[gh-symbolcollision-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/symbolcollision/badge.svg +[gh-zip-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/zip/badge.svg diff --git a/saraWhatsUp/Pods/FirebaseCore/FirebaseCore/Sources/FIRAnalyticsConfiguration.h b/saraWhatsUp/Pods/FirebaseCore/FirebaseCore/Sources/FIRAnalyticsConfiguration.h new file mode 100644 index 0000000..6429ac7 --- /dev/null +++ b/saraWhatsUp/Pods/FirebaseCore/FirebaseCore/Sources/FIRAnalyticsConfiguration.h @@ -0,0 +1,56 @@ +/* + * Copyright 2017 Google + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ + +#import + +/// Values stored in analyticsEnabledState.

Since 10.2, Xcode does not properly handle multi-platform +CocoaPods workspaces. + +Firestore has a self contained Xcode project.

Install `clang-format` and `mint`: + +```console +brew install clang-format@13 +brew install mint +``` + +### Running Unit Tests + +Select a scheme and press Command-u to build a component and run its unit tests. + +### Running Sample Apps +In order to run the sample apps and integration tests, you'll need a valid +`GoogleService-Info.plist` file. The Firebase Xcode project contains dummy plist +files without real values, but can be replaced with real plist files. To get your own +`GoogleService-Info.plist` files: + +1. Go to the [Firebase Console](https://console.firebase.google.com/) +2. Create a new Firebase project, if you don't already have one +3. For each sample app you want to test, create a new Firebase app with the sample app's bundle +identifier (e.g. `com.google.Database-Example`) +4. Download the resulting `GoogleService-Info.plist` and add it to the Xcode project. + +### Coverage Report Generation + +See [scripts/code_coverage_report/README.md](scripts/code_coverage_report/README.md). + +## Specific Component Instructions +See the sections below for any special instructions for those components. + +### Firebase Auth + +If you're doing specific Firebase Auth development, see +[the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about +building and running the FirebaseAuth pod along with various samples and tests. + +### Firebase Database + +The Firebase Database Integration tests can be run against a locally running Database Emulator +or against a production instance. + +To run against a local emulator instance, invoke `./scripts/run_database_emulator.sh start` before +running the integration test. + +To run against a production instance, provide a valid GoogleServices-Info.plist and copy it to +`FirebaseDatabase/Tests/Resources/GoogleService-Info.plist`. Your Security Rule must be set to +[public](https://firebase.google.com/docs/database/security/quickstart) while your tests are +running. + +### Firebase Performance Monitoring +If you're doing specific Firebase Performance Monitoring development, see +[the Performance README](FirebasePerformance/README.md) for instructions about building the SDK +and [the Performance TestApp README](FirebasePerformance/Tests/TestApp/README.md) for instructions about +integrating Performance with the dev test App. + +### Firebase Storage + +To run the Storage Integration tests, follow the instructions in +[FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m). + +#### Push Notifications + +Push notifications can only be delivered to specially provisioned App IDs in the developer portal. +In order to actually test receiving push notifications, you will need to: + +1. Change the bundle identifier of the sample app to something you own in your Apple Developer +account, and enable that App ID for push notifications. +2. You'll also need to +[upload your APNs Provider Authentication Key or certificate to the +Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs) +at **Project Settings > Cloud Messaging > [Your Firebase App]**. +3. Ensure your iOS device is added to your Apple Developer portal as a test device. + +#### iOS Simulator + +The iOS Simulator cannot register for remote notifications, and will not receive push notifications. +In order to receive push notifications, you'll have to follow the steps above and run the app on a +physical device. + +## Building with Firebase on Apple platforms + +Firebase 8.9.0 introduces official beta support for macOS, Catalyst, and tvOS. watchOS continues +to be community supported. Thanks to community contributions for many of the multi-platform PRs. + +At this time, most of Firebase's products are available across Apple platforms. There are still +a few gaps, especially on watchOS. For details about the current support matrix, see +[this chart](https://firebase.google.com/docs/ios/learn-more#firebase_library_support_by_platform) +in Firebase's documentation. + +### watchOS +Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and +work on watchOS. See the [Independent Watch App Sample](Example/watchOSSample). + +Keep in mind that watchOS is not officially supported by Firebase. While we can catch basic unit +test issues with GitHub Actions, there may be some changes where the SDK no longer works as expected +on watchOS. If you encounter this, please +[file an issue](https://github.com/firebase/firebase-ios-sdk/issues). + +During app setup in the console, you may get to a step that mentions something like "Checking if the +app has communicated with our servers". This relies on Analytics and will not work on watchOS. +**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected. + +#### Additional Crashlytics Notes +* watchOS has limited support. Due to watchOS restrictions, mach exceptions and signal crashes are +not recorded.

To access a local +source snapshot or unreleased branch, use Podfile directives like the following: + +To access FirebaseFirestore via a branch: +```ruby +pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' +pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' +``` + +To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do: + +```ruby +pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk' +pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk' +``` + +### Carthage (iOS only) + +Instructions for the experimental Carthage distribution are at +[Carthage](Carthage.md). + +### Using Firebase from a Framework or a library + +[Using Firebase from a Framework or a library](docs/firebase_in_libraries.md) + +## Development + +To develop Firebase software in this repository, ensure that you have at least +the following software: + + * Xcode 12.2 (or later) + +CocoaPods is still the canonical way to develop, but much of the repo now supports +development with Swift Package Manager. + +### CocoaPods + +Install + * CocoaPods 1.10.0 (or later) + * [CocoaPods generate](https://github.com/square/cocoapods-generate) + +For the pod that you want to develop: + +```ruby +pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios +``` + +Note: If the CocoaPods cache is out of date, you may need to run +`pod repo update` before the `pod gen` command. + +Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for +those platforms. Since 10.2, Xcode does not properly handle multi-platform +CocoaPods workspaces. + +Firestore has a self contained Xcode project.

Install `clang-format` and `mint`: + +```console +brew install clang-format@13 +brew install mint +``` + +### Running Unit Tests + +Select a scheme and press Command-u to build a component and run its unit tests. + +### Running Sample Apps +In order to run the sample apps and integration tests, you'll need a valid +`GoogleService-Info.plist` file. The Firebase Xcode project contains dummy plist +files without real values, but can be replaced with real plist files. To get your own +`GoogleService-Info.plist` files: + +1. Go to the [Firebase Console](https://console.firebase.google.com/) +2. Create a new Firebase project, if you don't already have one +3. For each sample app you want to test, create a new Firebase app with the sample app's bundle +identifier (e.g. `com.google.Database-Example`) +4. Download the resulting `GoogleService-Info.plist` and add it to the Xcode project. + +### Coverage Report Generation + +See [scripts/code_coverage_report/README.md](scripts/code_coverage_report/README.md). + +## Specific Component Instructions +See the sections below for any special instructions for those components. + +### Firebase Auth + +If you're doing specific Firebase Auth development, see +[the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about +building and running the FirebaseAuth pod along with various samples and tests. + +### Firebase Database + +The Firebase Database Integration tests can be run against a locally running Database Emulator +or against a production instance. + +To run against a local emulator instance, invoke `./scripts/run_database_emulator.sh start` before +running the integration test. + +To run against a production instance, provide a valid GoogleServices-Info.plist and copy it to +`FirebaseDatabase/Tests/Resources/GoogleService-Info.plist`. Your Security Rule must be set to +[public](https://firebase.google.com/docs/database/security/quickstart) while your tests are +running. + +### Firebase Performance Monitoring +If you're doing specific Firebase Performance Monitoring development, see +[the Performance README](FirebasePerformance/README.md) for instructions about building the SDK +and [the Performance TestApp README](FirebasePerformance/Tests/TestApp/README.md) for instructions about +integrating Performance with the dev test App. + +### Firebase Storage + +To run the Storage Integration tests, follow the instructions in +[FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m). + +#### Push Notifications + +Push notifications can only be delivered to specially provisioned App IDs in the developer portal. +In order to actually test receiving push notifications, you will need to: + +1. Change the bundle identifier of the sample app to something you own in your Apple Developer +account, and enable that App ID for push notifications. +2. You'll also need to +[upload your APNs Provider Authentication Key or certificate to the +Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs) +at **Project Settings > Cloud Messaging > [Your Firebase App]**. +3. Ensure your iOS device is added to your Apple Developer portal as a test device. + +#### iOS Simulator + +The iOS Simulator cannot register for remote notifications, and will not receive push notifications. +In order to receive push notifications, you'll have to follow the steps above and run the app on a +physical device. + +## Building with Firebase on Apple platforms + +Firebase 8.9.0 introduces official beta support for macOS, Catalyst, and tvOS. watchOS continues +to be community supported. Thanks to community contributions for many of the multi-platform PRs. + +At this time, most of Firebase's products are available across Apple platforms. There are still +a few gaps, especially on watchOS. For details about the current support matrix, see +[this chart](https://firebase.google.com/docs/ios/learn-more#firebase_library_support_by_platform) +in Firebase's documentation. + +### watchOS +Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and +work on watchOS. See the [Independent Watch App Sample](Example/watchOSSample). + +Keep in mind that watchOS is not officially supported by Firebase. While we can catch basic unit +test issues with GitHub Actions, there may be some changes where the SDK no longer works as expected +on watchOS. If you encounter this, please +[file an issue](https://github.com/firebase/firebase-ios-sdk/issues). + +During app setup in the console, you may get to a step that mentions something like "Checking if the +app has communicated with our servers". This relies on Analytics and will not work on watchOS. +**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected. + +#### Additional Crashlytics Notes +* watchOS has limited support. Due to watchOS restrictions, mach exceptions and signal crashes are +not recorded. (Crashes in SwiftUI are generated as mach exceptions, so will not be recorded) + +## Combine +Thanks to contributions from the community, _FirebaseCombineSwift_ contains support for Apple's Combine +framework. This module is currently under development, and not yet supported for use in production +environments. Fore more details, please refer to the [docs](FirebaseCombineSwift/README.md). + +## Roadmap + +See [Roadmap](ROADMAP.md) for more about the Firebase Apple SDK Open Source +plans and directions. + +## Contributing + +See [Contributing](CONTRIBUTING.md) for more information on contributing to the Firebase +Apple SDK. + +## License + +The contents of this repository are licensed under the +[Apache License, version 2.0](http://www.apache.org/licenses/LICENSE-2.0). + +Your use of Firebase is governed by the +[Terms of Service for Firebase Services](https://firebase.google.com/terms/). + +[gh-actions]: https://github.com/firebase/firebase-ios-sdk/actions +[gh-abtesting-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/abtesting/badge.svg +[gh-appcheck-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/app_check/badge.svg +[gh-appdistribution-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/appdistribution/badge.svg +[gh-auth-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/auth/badge.svg +[gh-cocoapods-integration-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/cocoapods-integration/badge.svg +[gh-core-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/core/badge.svg +[gh-core-diagnostics-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/core-diagnostics/badge.svg +[gh-crashlytics-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/crashlytics/badge.svg +[gh-database-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/database/badge.svg +[gh-datatransport-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/datatransport/badge.svg +[gh-dynamiclinks-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/dynamiclinks/badge.svg +[gh-firebasepod-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/firebasepod/badge.svg +[gh-firestore-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/firestore/badge.svg +[gh-functions-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/functions/badge.svg +[gh-google-utilities-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/google-utilities/badge.svg +[gh-google-utilities-components-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/google-utilities-components/badge.svg +[gh-inappmessaging-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/inappmessaging/badge.svg +[gh-interop-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/interop/badge.svg +[gh-messaging-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/messaging/badge.svg +[gh-mlmodeldownloader-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/mlmodeldownloader/badge.svg +[gh-performance-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/performance/badge.svg +[gh-remoteconfig-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/remoteconfig/badge.svg +[gh-storage-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/storage/badge.svg +[gh-symbolcollision-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/symbolcollision/badge.svg +[gh-zip-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/zip/badge.svg diff --git a/saraWhatsUp/Pods/FirebaseDatabase/FirebaseAppCheck/Sources/Interop/FIRAppCheckInterop.h b/saraWhatsUp/Pods/FirebaseDatabase/FirebaseAppCheck/Sources/Interop/FIRAppCheckInterop.h new file mode 100644 index 0000000..834b740 --- /dev/null +++ b/saraWhatsUp/Pods/FirebaseDatabase/FirebaseAppCheck/Sources/Interop/FIRAppCheckInterop.h @@ -0,0 +1,48 @@ +/* + * Copyright 2020 Google LLC + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ + +#import + +@protocol FIRAppCheckTokenResultInterop; + +NS_ASSUME_NONNULL_BEGIN + +NS_SWIFT_NAME(AppCheckTokenHandlerInterop) +typedef void (^FIRAppCheckTokenHandlerInterop)(id tokenResult); + +@protocol FIRAppCheckInterop + +/// Retrieve a cached or generate a new FAA Token.

It is reproduced here in a slightly edited form for + convenience. + + A 65-character subset of US-ASCII is used, enabling 6 bits to be + represented per printable character. (The extra 65th character, "=", + is used to signify a special processing function.) + + The encoding process represents 24-bit groups of input bits as output + strings of 4 encoded characters. Proceeding from left to right, a + 24-bit input group is formed by concatenating 3 8-bit input groups. + These 24 bits are then treated as 4 concatenated 6-bit groups, each + of which is translated into a single digit in the base64 alphabet. + + Each 6-bit group is used as an index into an array of 64 printable + characters.

To access a local +source snapshot or unreleased branch, use Podfile directives like the following: + +To access FirebaseFirestore via a branch: +```ruby +pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' +pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' +``` + +To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do: + +```ruby +pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk' +pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk' +``` + +### Carthage (iOS only) + +Instructions for the experimental Carthage distribution are at +[Carthage](Carthage.md). + +### Using Firebase from a Framework or a library + +[Using Firebase from a Framework or a library](docs/firebase_in_libraries.md) + +## Development + +To develop Firebase software in this repository, ensure that you have at least +the following software: + + * Xcode 12.2 (or later) + +CocoaPods is still the canonical way to develop, but much of the repo now supports +development with Swift Package Manager. + +### CocoaPods + +Install + * CocoaPods 1.10.0 (or later) + * [CocoaPods generate](https://github.com/square/cocoapods-generate) + +For the pod that you want to develop: + +```ruby +pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios +``` + +Note: If the CocoaPods cache is out of date, you may need to run +`pod repo update` before the `pod gen` command. + +Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for +those platforms. Since 10.2, Xcode does not properly handle multi-platform +CocoaPods workspaces. + +Firestore has a self contained Xcode project.

Install `clang-format` and `mint`: + +```console +brew install clang-format@13 +brew install mint +``` + +### Running Unit Tests + +Select a scheme and press Command-u to build a component and run its unit tests. + +### Running Sample Apps +In order to run the sample apps and integration tests, you'll need a valid +`GoogleService-Info.plist` file. The Firebase Xcode project contains dummy plist +files without real values, but can be replaced with real plist files. To get your own +`GoogleService-Info.plist` files: + +1. Go to the [Firebase Console](https://console.firebase.google.com/) +2. Create a new Firebase project, if you don't already have one +3. For each sample app you want to test, create a new Firebase app with the sample app's bundle +identifier (e.g. `com.google.Database-Example`) +4. Download the resulting `GoogleService-Info.plist` and add it to the Xcode project. + +### Coverage Report Generation + +See [scripts/code_coverage_report/README.md](scripts/code_coverage_report/README.md). + +## Specific Component Instructions +See the sections below for any special instructions for those components. + +### Firebase Auth + +If you're doing specific Firebase Auth development, see +[the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about +building and running the FirebaseAuth pod along with various samples and tests. + +### Firebase Database + +The Firebase Database Integration tests can be run against a locally running Database Emulator +or against a production instance. + +To run against a local emulator instance, invoke `./scripts/run_database_emulator.sh start` before +running the integration test. + +To run against a production instance, provide a valid GoogleServices-Info.plist and copy it to +`FirebaseDatabase/Tests/Resources/GoogleService-Info.plist`. Your Security Rule must be set to +[public](https://firebase.google.com/docs/database/security/quickstart) while your tests are +running. + +### Firebase Performance Monitoring +If you're doing specific Firebase Performance Monitoring development, see +[the Performance README](FirebasePerformance/README.md) for instructions about building the SDK +and [the Performance TestApp README](FirebasePerformance/Tests/TestApp/README.md) for instructions about +integrating Performance with the dev test App. + +### Firebase Storage + +To run the Storage Integration tests, follow the instructions in +[FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m). + +#### Push Notifications + +Push notifications can only be delivered to specially provisioned App IDs in the developer portal. +In order to actually test receiving push notifications, you will need to: + +1. Change the bundle identifier of the sample app to something you own in your Apple Developer +account, and enable that App ID for push notifications. +2. You'll also need to +[upload your APNs Provider Authentication Key or certificate to the +Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs) +at **Project Settings > Cloud Messaging > [Your Firebase App]**. +3. Ensure your iOS device is added to your Apple Developer portal as a test device. + +#### iOS Simulator + +The iOS Simulator cannot register for remote notifications, and will not receive push notifications. +In order to receive push notifications, you'll have to follow the steps above and run the app on a +physical device. + +## Building with Firebase on Apple platforms + +Firebase 8.9.0 introduces official beta support for macOS, Catalyst, and tvOS. watchOS continues +to be community supported. Thanks to community contributions for many of the multi-platform PRs. + +At this time, most of Firebase's products are available across Apple platforms. There are still +a few gaps, especially on watchOS. For details about the current support matrix, see +[this chart](https://firebase.google.com/docs/ios/learn-more#firebase_library_support_by_platform) +in Firebase's documentation. + +### watchOS +Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and +work on watchOS. See the [Independent Watch App Sample](Example/watchOSSample). + +Keep in mind that watchOS is not officially supported by Firebase. While we can catch basic unit +test issues with GitHub Actions, there may be some changes where the SDK no longer works as expected +on watchOS. If you encounter this, please +[file an issue](https://github.com/firebase/firebase-ios-sdk/issues). + +During app setup in the console, you may get to a step that mentions something like "Checking if the +app has communicated with our servers". This relies on Analytics and will not work on watchOS. +**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected. + +#### Additional Crashlytics Notes +* watchOS has limited support. Due to watchOS restrictions, mach exceptions and signal crashes are +not recorded. (Crashes in SwiftUI are generated as mach exceptions, so will not be recorded) + +## Combine +Thanks to contributions from the community, _FirebaseCombineSwift_ contains support for Apple's Combine +framework.

To access a local +source snapshot or unreleased branch, use Podfile directives like the following: + +To access FirebaseFirestore via a branch: +```ruby +pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' +pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master' +``` + +To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do: + +```ruby +pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk' +pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk' +``` + +### Carthage (iOS only) + +Instructions for the experimental Carthage distribution are at +[Carthage](Carthage.md). + +### Using Firebase from a Framework or a library + +[Using Firebase from a Framework or a library](docs/firebase_in_libraries.md) + +## Development + +To develop Firebase software in this repository, ensure that you have at least +the following software: + + * Xcode 12.2 (or later) + +CocoaPods is still the canonical way to develop, but much of the repo now supports +development with Swift Package Manager. + +### CocoaPods + +Install + * CocoaPods 1.10.0 (or later) + * [CocoaPods generate](https://github.com/square/cocoapods-generate) + +For the pod that you want to develop: + +```ruby +pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios +``` + +Note: If the CocoaPods cache is out of date, you may need to run +`pod repo update` before the `pod gen` command. + +Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for +those platforms. Since 10.2, Xcode does not properly handle multi-platform +CocoaPods workspaces. + +Firestore has a self contained Xcode project.

Install `clang-format` and `mint`: + +```console +brew install clang-format@13 +brew install mint +``` + +### Running Unit Tests + +Select a scheme and press Command-u to build a component and run its unit tests. + +### Running Sample Apps +In order to run the sample apps and integration tests, you'll need a valid +`GoogleService-Info.plist` file. The Firebase Xcode project contains dummy plist +files without real values, but can be replaced with real plist files. To get your own +`GoogleService-Info.plist` files: + +1. Go to the [Firebase Console](https://console.firebase.google.com/) +2. Create a new Firebase project, if you don't already have one +3. For each sample app you want to test, create a new Firebase app with the sample app's bundle +identifier (e.g. `com.google.Database-Example`) +4. Download the resulting `GoogleService-Info.plist` and add it to the Xcode project. + +### Coverage Report Generation + +See [scripts/code_coverage_report/README.md](scripts/code_coverage_report/README.md). + +## Specific Component Instructions +See the sections below for any special instructions for those components. + +### Firebase Auth + +If you're doing specific Firebase Auth development, see +[the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about +building and running the FirebaseAuth pod along with various samples and tests. + +### Firebase Database + +The Firebase Database Integration tests can be run against a locally running Database Emulator +or against a production instance. + +To run against a local emulator instance, invoke `./scripts/run_database_emulator.sh start` before +running the integration test. + +To run against a production instance, provide a valid GoogleServices-Info.plist and copy it to +`FirebaseDatabase/Tests/Resources/GoogleService-Info.plist`. Your Security Rule must be set to +[public](https://firebase.google.com/docs/database/security/quickstart) while your tests are +running. + +### Firebase Performance Monitoring +If you're doing specific Firebase Performance Monitoring development, see +[the Performance README](FirebasePerformance/README.md) for instructions about building the SDK +and [the Performance TestApp README](FirebasePerformance/Tests/TestApp/README.md) for instructions about +integrating Performance with the dev test App. + +### Firebase Storage + +To run the Storage Integration tests, follow the instructions in +[FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m). + +#### Push Notifications + +Push notifications can only be delivered to specially provisioned App IDs in the developer portal. +In order to actually test receiving push notifications, you will need to: + +1. Change the bundle identifier of the sample app to something you own in your Apple Developer +account, and enable that App ID for push notifications. +2. You'll also need to +[upload your APNs Provider Authentication Key or certificate to the +Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs) +at **Project Settings > Cloud Messaging > [Your Firebase App]**. +3. Ensure your iOS device is added to your Apple Developer portal as a test device. + +#### iOS Simulator + +The iOS Simulator cannot register for remote notifications, and will not receive push notifications. +In order to receive push notifications, you'll have to follow the steps above and run the app on a +physical device. + +## Building with Firebase on Apple platforms + +Firebase 8.9.0 introduces official beta support for macOS, Catalyst, and tvOS. watchOS continues +to be community supported. Thanks to community contributions for many of the multi-platform PRs. + +At this time, most of Firebase's products are available across Apple platforms. There are still +a few gaps, especially on watchOS. For details about the current support matrix, see +[this chart](https://firebase.google.com/docs/ios/learn-more#firebase_library_support_by_platform) +in Firebase's documentation. + +### watchOS +Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and +work on watchOS. See the [Independent Watch App Sample](Example/watchOSSample). + +Keep in mind that watchOS is not officially supported by Firebase. While we can catch basic unit +test issues with GitHub Actions, there may be some changes where the SDK no longer works as expected +on watchOS. If you encounter this, please +[file an issue](https://github.com/firebase/firebase-ios-sdk/issues). + +During app setup in the console, you may get to a step that mentions something like "Checking if the +app has communicated with our servers". This relies on Analytics and will not work on watchOS. +**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected. + +#### Additional Crashlytics Notes +* watchOS has limited support. Due to watchOS restrictions, mach exceptions and signal crashes are +not recorded. (Crashes in SwiftUI are generated as mach exceptions, so will not be recorded) + +## Combine +Thanks to contributions from the community, _FirebaseCombineSwift_ contains support for Apple's Combine +framework. This module is currently under development, and not yet supported for use in production +environments.

This will only work on jailbroken devices as +/// codesignature validation has been removed.

This encrypts the binary so that decryption keys are needed in order +to make the binary readable. When iOS executes the binary, the decryption keys +are used to decrypt the binary into a readable state where it is then loaded +into memory and executed. iOS can tell the encryption status of a binary via the +cryptid structure member of LC_ENCRYPTION_INFO MachO load command. If cryptid is +a non-zero value then the binary is encrypted. + +'Cracking' works by letting the kernel decrypt the binary then siphoning the +decrypted data into a new binary file, resigning, and repackaging. This will +only work on jailbroken devices as codesignature validation has been removed. +Resigning takes place because while the codesignature doesn't have to be valid +thanks to the jailbreak, it does have to be in place unless you have AppSync or +similar to disable codesignature checks. + +More information at Landon +Fuller's blog diff --git a/saraWhatsUp/Pods/GoogleUtilities/README.md b/saraWhatsUp/Pods/GoogleUtilities/README.md new file mode 100644 index 0000000..ff9fe1a --- /dev/null +++ b/saraWhatsUp/Pods/GoogleUtilities/README.md @@ -0,0 +1,189 @@ +[![Version](https://img.shields.io/cocoapods/v/GoogleUtilities.svg?style=flat)](https://cocoapods.org/pods/GoogleUtilities) +[![License](https://img.shields.io/cocoapods/l/GoogleUtilities.svg?style=flat)](https://cocoapods.org/pods/GoogleUtilities) +[![Platform](https://img.shields.io/cocoapods/p/GoogleUtilities.svg?style=flat)](https://cocoapods.org/pods/GoogleUtilities) + +[![Actions Status][gh-google-utilities-badge]][gh-actions] + +# GoogleUtilities + +GoogleUtilities provides a set of utilities for Firebase and other Google SDKs for Apple platform +development. + +The utilities are not directly supported for non-Google library usage. + +## Integration Testing +These instructions apply to minor and patch version updates.

This encrypts the binary so that decryption keys are needed in order +to make the binary readable. When iOS executes the binary, the decryption keys +are used to decrypt the binary into a readable state where it is then loaded +into memory and executed. iOS can tell the encryption status of a binary via the +cryptid structure member of LC_ENCRYPTION_INFO MachO load command. If cryptid is +a non-zero value then the binary is encrypted. + +'Cracking' works by letting the kernel decrypt the binary then siphoning the +decrypted data into a new binary file, resigning, and repackaging. This will +only work on jailbroken devices as codesignature validation has been removed. +Resigning takes place because while the codesignature doesn't have to be valid +thanks to the jailbreak, it does have to be in place unless you have AppSync or +similar to disable codesignature checks. + +More information at Landon +Fuller's blog + + +## PromisesObjC + + + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

This encrypts the binary so that decryption keys are needed in order +to make the binary readable. When iOS executes the binary, the decryption keys +are used to decrypt the binary into a readable state where it is then loaded +into memory and executed. iOS can tell the encryption status of a binary via the +cryptid structure member of LC_ENCRYPTION_INFO MachO load command. If cryptid is +a non-zero value then the binary is encrypted. + +'Cracking' works by letting the kernel decrypt the binary then siphoning the +decrypted data into a new binary file, resigning, and repackaging. This will +only work on jailbroken devices as codesignature validation has been removed. +Resigning takes place because while the codesignature doesn't have to be valid +thanks to the jailbreak, it does have to be in place unless you have AppSync or +similar to disable codesignature checks. + +More information at <a href="http://landonf.org/2009/02/index.html">Landon +Fuller's blog</a> + + License + Apache + Title + GoogleUtilities + Type + PSGroupSpecifier + + + FooterText + + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

The results are somewhat noisy, but should +be enough to get a ballpark performance estimate. + +## Setup + +We use a database with a million entries. Each entry has a 16 byte +key, and a 100 byte value. Values used by the benchmark compress to +about half their original size. + + LevelDB: version 1.1 + Date: Sun May 1 12:11:26 2011 + CPU: 4 x Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz + CPUCache: 4096 KB + Keys: 16 bytes each + Values: 100 bytes each (50 bytes after compression) + Entries: 1000000 + Raw Size: 110.6 MB (estimated) + File Size: 62.9 MB (estimated) + +## Write performance + +The "fill" benchmarks create a brand new database, in either +sequential, or random order. The "fillsync" benchmark flushes data +from the operating system to the disk after every operation; the other +write operations leave the data sitting in the operating system buffer +cache for a while. The "overwrite" benchmark does random writes that +update existing keys in the database. + + fillseq : 1.765 micros/op; 62.7 MB/s + fillsync : 268.409 micros/op; 0.4 MB/s (10000 ops) + fillrandom : 2.460 micros/op; 45.0 MB/s + overwrite : 2.380 micros/op; 46.5 MB/s + +Each "op" above corresponds to a write of a single key/value pair. +I.e., a random write benchmark goes at approximately 400,000 writes per second. + +Each "fillsync" operation costs much less (0.3 millisecond) +than a disk seek (typically 10 milliseconds). We suspect that this is +because the hard disk itself is buffering the update in its memory and +responding before the data has been written to the platter. This may +or may not be safe based on whether or not the hard disk has enough +power to save its memory in the event of a power failure. + +## Read performance + +We list the performance of reading sequentially in both the forward +and reverse direction, and also the performance of a random lookup. +Note that the database created by the benchmark is quite small. +Therefore the report characterizes the performance of leveldb when the +working set fits in memory. The cost of reading a piece of data that +is not present in the operating system buffer cache will be dominated +by the one or two disk seeks needed to fetch the data from disk. +Write performance will be mostly unaffected by whether or not the +working set fits in memory. + + readrandom : 16.677 micros/op; (approximately 60,000 reads per second) + readseq : 0.476 micros/op; 232.3 MB/s + readreverse : 0.724 micros/op; 152.9 MB/s + +LevelDB compacts its underlying storage data in the background to +improve read performance. The results listed above were done +immediately after a lot of random writes. The results after +compactions (which are usually triggered automatically) are better. + + readrandom : 11.602 micros/op; (approximately 85,000 reads per second) + readseq : 0.423 micros/op; 261.8 MB/s + readreverse : 0.663 micros/op; 166.9 MB/s + +Some of the high cost of reads comes from repeated decompression of blocks +read from disk. If we supply enough cache to the leveldb so it can hold the +uncompressed blocks in memory, the read performance improves again: + + readrandom : 9.775 micros/op; (approximately 100,000 reads per second before compaction) + readrandom : 5.215 micros/op; (approximately 190,000 reads per second after compaction) + +## Repository contents + +See [doc/index.md](doc/index.md) for more explanation.

You can get +an iterator from a DB object. + +* **include/write_batch.h**: Interface for atomically applying multiple +updates to a database. + +* **include/slice.h**: A simple module for maintaining a pointer and a +length into some other byte array. + +* **include/status.h**: Status is returned from many of the public interfaces +and is used to report success and various kinds of errors. + +* **include/env.h**: +Abstraction of the OS environment.

It is +especially suitable for use in microcontrollers, but fits any memory +restricted system. + +* **Homepage:** https://jpa.kapsi.fi/nanopb/ +* **Documentation:** https://jpa.kapsi.fi/nanopb/docs/ +* **Downloads:** https://jpa.kapsi.fi/nanopb/download/ +* **Forum:** https://groups.google.com/forum/#!forum/nanopb + + + +Using the nanopb library +------------------------ +To use the nanopb library, you need to do two things: + +1. Compile your .proto files for nanopb, using `protoc`. +2. Include *pb_encode.c*, *pb_decode.c* and *pb_common.c* in your project. + +The easiest way to get started is to study the project in "examples/simple". +It contains a Makefile, which should work directly under most Linux systems. +However, for any other kind of build system, see the manual steps in +README.txt in that folder. + + + +Using the Protocol Buffers compiler (protoc) +-------------------------------------------- +The nanopb generator is implemented as a plugin for the Google's own `protoc` +compiler. This has the advantage that there is no need to reimplement the +basic parsing of .proto files. However, it does mean that you need the +Google's protobuf library in order to run the generator. + +If you have downloaded a binary package for nanopb (either Windows, Linux or +Mac OS X version), the `protoc` binary is included in the 'generator-bin' +folder. In this case, you are ready to go. Simply run this command: + + generator-bin/protoc --nanopb_out=. myprotocol.proto + +However, if you are using a git checkout or a plain source distribution, you +need to provide your own version of `protoc` and the Google's protobuf library. +On Linux, the necessary packages are `protobuf-compiler` and `python-protobuf`. +On Windows, you can either build Google's protobuf library from source or use +one of the binary distributions of it. In either case, if you use a separate +`protoc`, you need to manually give the path to nanopb generator: + + protoc --plugin=protoc-gen-nanopb=nanopb/generator/protoc-gen-nanopb ... + + + +Running the tests +----------------- +If you want to perform further development of the nanopb core, or to verify +its functionality using your compiler and platform, you'll want to run the +test suite. The build rules for the test suite are implemented using Scons, +so you need to have that installed (ex: `sudo apt install scons` on Ubuntu). To run the tests: + + cd tests + scons + +This will show the progress of various test cases. If the output does not +end in an error, the test cases were successful. + +Note: Mac OS X by default aliases 'clang' as 'gcc', while not actually +supporting the same command line options as gcc does. To run tests on +Mac OS X, use: "scons CC=clang CXX=clang". Same way can be used to run +tests with different compilers on any platform. diff --git a/saraWhatsUp/Pods/nanopb/pb.h b/saraWhatsUp/Pods/nanopb/pb.h new file mode 100644 index 0000000..236e894 --- /dev/null +++ b/saraWhatsUp/Pods/nanopb/pb.h @@ -0,0 +1,599 @@ +/* Common parts of the nanopb library.
