Thank you very much. I have updated the example app accordingly and in my current project I will implement the favourites logic using a custom Id.

Thanks, that's a hell of a hack...it worked. Kinda makes sense - ipa is a bundle.

@notfrancis: I suggest you post a ticket to Apple via the feedback assistant. I hope Apple doesn't expect everyone to switch to SwiftData immediately. Given the experience with SwiftUI in its early stage, I fear that SwiftData isn't ready for production yet...

still happening as of Oct 3rd trying to install the release version of my app directly from xCode 15.0 to my iPhone with iOS 17.0.2. There seems to be some kind of infinite loop with that warning message, ultimately it crashes during startup. Strange: when I use the debug version of my app, the warning appears only a few times and the app is installed normally and can run.

Adding the bundle name to the info.plist didn't work for me. Even after archiving my app again afterwards, the error still persists. Archiving the macOS version and opening it in the Application folder is working fine. My iPad is still on iPadOS 16.7 and I can install my app with Xcode 15 without any problem. So this is definitely an iOS 17 problem.
