We're attempting to upgrade to XCode 16 but are encountering a consistent crash when doing so. The actual exception message comes from the UICollectionView, with this message and stack trace. *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Expected dequeued view to be returned to the collection view in preparation for display. When the collection view's data source is asked to provide a view for a given index path, ensure that a single view is dequeued and returned to the collection view. Avoid dequeuing views without a request from the collection view. For retrieving an existing view in the collection view, use -[UICollectionView cellForItemAtIndexPath:] or -[UICollectionView supplementaryViewForElementKind:atIndexPath:].

I've seen various similiar posts related to iOS 18 but none with a resolution

We've received reports from users with iPhone 14 pro models that their phones are crashing and turning off entirely when viewing live streams in our app. These streams have been working since iOS 10. I've filed a bug report through the feedback assistant (FB11839509) and have still heard nothing back.

We can now create dedicated watch extension unit test targets in XCode 12.5. I've had no trouble getting this to work via XCode, but I'm struggling to work out how to correctly build and run the tests from the command line using xcodebuild. Running the test target using xcodebuild always produces the same error related to unavailable destinations, despite the destination being available. xcodebuild: error: Unable to find a destination matching the provided destination specifier: { name:iPhone 12 Pro Max } The requested device could not be found because no available devices matched the request.
