There is a workaround for Xcode 15.x running on MacOS 15. Just go to the Xcode 15.x folder, show its package content, go to Contents->MacOS, and double click the executable file Xcode. This workaround works perfectly!

Just now, I found a phenomenon that if an app has been installed on iOS 15, even if it is deleted, reinstalled, or restarted, the selection of some system permissions of the app is still remembered, so there is no need to reselect (such as user tracking, location, photos, camera, etc.), and there is no pop-up box, except for notifications.
