It occurs on device and simulator with iOS <13.2. On 13.2 everything is ok.
Built with XCode 11.2 from App Store (11B52)
With 'All Exceptions' breakpoint XCode catches a line where it tries to load a view from .xib which has UITextView as subview (connected as IBOutlet).
Then I get:
Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named _UITextLayoutView because no class named _UITextLayoutView was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target)'
