I have an app that generally works fine, but I got field reports that some parts of the app becoming unresponsive at times.
After endless searching I was finally able to reproduce the situation, and found the following quite strange view hierarchy:
UIWindowScene - (Foreground Active)
UIWindow
UITextEffectsWindow
UIInputWindowController
UIInputSetContainerView
UIInputSetHostView
UIEditingOverlayViewController
UIEditingOverlayGestureView
Some internet search revealed that these are private classes probably linked to undo functionality introduced in iOS13.
What is happening here, and how to prevent that?
Thanks for any insight!
