In iOS 26, adopting the UI Scene Lifecycle will become mandatory for apps built with the latest SDK. This means that you will need to use UIScene instead of AppDelegate for managing your app's lifecycle. While supporting multiple scenes is encouraged, the adoption of the Scene Lifecycle is required. This change is part of Apple's efforts to make apps more flexible and portable.
