AppDelegate is still supported, but Apple is moving towards making the UI Scene Lifecycle mandatory in future releases. According to the session Make your UIKit app more flexible, adopting the UI Scene Lifecycle will be required when building with the latest SDK following iOS 26. While supporting multiple scenes is encouraged, only the adoption of the Scene Lifecycle is required. This means that while you can still use AppDelegate, you should plan to migrate to using SceneDelegate to ensure compatibility with future iOS versions.
