May I expect an answer ?

Configuration App built on Xcode 15.2 on MacOS 14.2.1. App running on iOS 17.2.1 = > OK App running on MacOS 14.2.1 => NOT OK TN3152 Fully applied. Works fine on iOS 17. Not on MacOS 14. Code info.plist is correctely updated (see below). I call if try await eventStore.requestFullAccessToEvents() and get a FALSE return (no error thrown). After call returned false I get EKEventStore.authorizationStatus(for: .event) == .notDetermined The user is NEVER prompted by the App for access authorization (no show). Note I had the same issue with Xcode 14 and running he app on MacOS 16 (in MyMac (designed for iPad) as well).

Yes I did. Rebooted several times. iOS 13.5 simulator boots quite well but iOS 14 simulator always fails to boot. I reinstalled Xcode from scratch, same issue. All works fine on my iMac which is much older.
