I rebooted the iPhone. after that it was ok again.

Thanks! I have these settings: Project iOS Deployment Target = 14.4 Target App Deployment Info = 14.0 Target Widget Deployment Info = 14.4 Does the Target App Deployment Info take precedence over the iOS Deployment Target? I think the Target Deployment Version should be = iOS Deployment Target Version and not the other way around. Maybe a bug in Xcode?

Thanks. Where to file such a bug? The feedback App no one ever replies there.
