Yes, the application delegate is being deprecated. According to the session What’s new in UIKit, Apple is deprecating many UI application-focused APIs, including legacy UI application delegate callbacks and UIApplication launch option keys. The only remaining initializer for UIWindow is the init window scene initializer. Following iOS 26, any UIKit app built with the latest SDK will be required to use the UI Scene lifecycle, otherwise, it will not launch.
