+To test your in-app purchases, you have to *run the app on an actual device*. Using the iOS Simulator, they will always fail as the simulator cannot connect to the iTunes Store. However, you can do certain tasks like using `loadProducts` without the need to run on a real device.
 
 1. Set up a test account ("Sandbox Tester") in iTunes Connect. See the official documentation [here](https://developer.apple.com/library/ios/documentation/LanguagesUtilities/Conceptual/iTunesConnect_Guide/Chapters/SettingUpUserAccounts.html#//apple_ref/doc/uid/TP40011225-CH25-SW9).
