Class Scene​Delegate

Use this method to optionally configure and attach the UIWindow window to the provided UIWindowScene scene. If using a storyboard, the window property will automatically be initialized and attached to the scene. This delegate does not imply the connecting scene or session are new (see application:configurationForConnectingSceneSession instead).

Called as the scene is being released by the system. This occurs shortly after the scene enters the background, or when its session is discarded. Release any resources associated with this scene that can be re-created the next time the scene connects. The scene may re-connect later, as its session was not neccessarily discarded (see application:didDiscardSceneSessions instead).

Called when the scene has moved from an inactive state to an active state. Use this method to restart any tasks that were paused (or not yet started) when the scene was inactive.

Called when the scene will move from an active state to an inactive state. This may occur due to temporary interruptions (ex. an incoming phone call).

Called as the scene transitions from the background to the foreground. Use this method to undo the changes made on entering the background.

Called as the scene transitions from the foreground to the background. Use this method to save data, release shared resources, and store enough scene-specific state information to restore the scene back to its current state.
