Yes, adopting the UI Scene Lifecycle will become mandatory in the next major release following iOS 26. While supporting multiple scenes is encouraged, only the adoption of the Scene Lifecycle is required. This means that the use of SceneDelegate will be necessary when building with the latest SDK. For more details on how to adopt the UI Scene Lifecycle, you can refer to the session Make your UIKit app more flexible (02:01).
