To recognize when a view controller is dismissed in UIKit, you can use the view controller lifecycle methods. Specifically, you can track the state during transitions using methods like viewDidAppear and viewDidDisappear. These methods are guaranteed to be called at the end of the transition if you're using the navigation controller.
For more detailed information on handling view controller lifecycle and appearance callbacks in UIKit, you can refer to the session Enhance your UI animations and transitions.
