UIScene notifications are the correct way to track window focus on iOS 13.0+, because the Key Window API is scene-level on iOS 13.0+, but we need to maintain support for iOS 12 and earlier. Implementation strategy: - iOS 13.0+: Use UIScene notifications (DidActivate/WillDeactivate) - iOS 12 and earlier: Keep existing UIWindow notifications as fallback - Add runtime version checks to select the appropriate API Key changes in os_ios.m: - Add @available(iOS 13.0, *) checks - Register both notification types with conditional logic - Ensure proper cleanup of observers when moving between windows See: https://developer.apple.com/documentation/uikit/uiscene?language=objc Fixes: https://lists.sr.ht/~eliasnaur/gio/%3CCAMAFT9Uyh_JWrkQQt+AmekJWFBqhZPsP_3ZxC1fUNB+=VGGorw@mail.gmail.com%3E Signed-off-by: CoyAce <akeycoy@gmail.com> Signed-off-by: Elias Naur <mail@eliasnaur.com>
