Since the release of iOS 13 we are getting crash reports from Itunes Connect saying UIKitCore: -[UIResponder doesNotRecognizeSelector:].
Can anyone help me understand the following crash report?
The crash seems to happen only at launch.
Following https://developer.apple.com/library/archive/technotes/tn2151/_index.html -[NSObject(NSObject) doesNotRecognizeSelector:] occurs when a new object is allocated in the memory previously occupied by the deallocated object. Profiling the app with the Zombies instrument doesn't really help, I just can't reproduce the situation.
Please understand that I had to **** out the actual app name.
