        My app ran without any crashes while using Xcode 10.3.  After updating to XCode 11.1, 11.2 and 11.2.1, my app experienced a crash:

         

        *** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named _UIScrollerImpContainerView because no class named _UIScrollerImpContainerView 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)'

         

        This crash seems to occur during before any of my views appear on the screen.

         

        Similar problem has been see on apple developper forum : https://forums.developer.apple.com/thread/125287

         

        Any idea on the cause or solution?

         

        Thanks.
