Crashes in iOS 11

[sachinrekhi]

This approach seems to crash the app when used in iOS 11. Specifically when the following line is called, the app will crash within a few seconds (though not immediately on this line of code). Comment out this line of code stops the app from crashing, but the form assistant is still displayed.

// remove the form accessory bar
[peripheralView removeFromSuperview];

The issue is specifically removing the view from the superview. If you set the opacity of the view to 0, then the app also doesn't crash. Also if you set the frame to CGRectZero, it also doesn't crash. But I haven't been able to do so in such a way to recover the screen pixels that the form assistant previously took up.

Has anyone found a suitable workaround for removing the form assistant in iOS11?
