I can still see the issue, even on Xcode 16.0 beta 6. If I run the app on ios 16 or 17, all works. On iOS 18 I get this error.

@DTS Engineer the issue can be easily reproduced even on Apple's own sample code https://developer.apple.com/documentation/swiftui/building-a-document-based-app-with-swiftui, still present on Xcode 16 RC and corresponding iOS 18 simulator
