iOS 14.2: rejected resignFirstResponder when being removed from hierarchy

[mschonvogel]

Example[44229:872073] [View] First responder warning: '<InputBarAccessoryView.InputTextView: 0x7fb27d02ca00; baseClass = UITextView; frame = (0 0; 291 38); text = ''; clipsToBounds = YES; gestureRecognizers = <NSArray: 0x6000013b6b80>; layer = <CALayer: 0x600001d96e40>; contentOffset: {0, 0}; contentSize: {142.5, 36.5}; adjustedContentInset: {0, 0, 0, 0}>' rejected resignFirstResponder when being removed from hierarchy

To Reproduce

1. Open the Example app and pick any example in the InputAccessoryView section
2. Tap into textfield
3. Slide it down to end editing

Expected behavior resignFirstResponder and hence keyboardManager.on(event: .willHide) should get called (it's getting called in Simulator but not on a real device (tried it with iPhone 11 pro)

I think it's a bug in iOS 14.2 https://openradar.appspot.com/FB8832021

Environment 5.2.2 - Example app

Yep, same here. If I call resignFirstResponder() in viewWillDisappear() the willHide notification gets fired as intended. When resignFirstResponder() called in other methods the notification does not work. Have tested in both 14.2 and 14.3

Thank for letting us know it's probably an iOS thing!

Any workarounds? @Kaspik @mschonvogel @acydapp

Got this solution from @mschonvogel and it works for my case: try textview's didEndEditing method
