We started getting this warning also when uploading to TestFlight with Xcode 16.3. The app does not use any 3rd party libraries and does not use Push Notifications (and does not implement the above API).
Hint to Apple: When we last uploaded with Xcode 16.2, this warning did not occur. This warning started after upgrading to Xcode 16.3.
