I noticed this. If at least one (!) other app is running in the background: Open your app Kill/close your app Quickly re-run your app Almost everytime app crashes This has to be iOS 15 bug.

I noticed I cannot set price for more than 2 months in advance? W00t ?

Every time I have this RANDOM issue I open keychain and change Apple Worldwide Developer Relations Certification Authority: Use system defaults Save Back to -> Always trust

Will interacting with Dynamic Island be possible only with Live Activities? Or will interacting with Dynamic Island also be possible for something like this: info messages (etc.) inside app ?

Also in Xcode 14 final release.

Does this happen because no more memory available or? I have same exception quite very rare and randomly in my app.

Same...
