iOS 26 require change current App

To ensure your app is compatible with iOS 26, there are several important changes you need to be aware of:

1. UI Scene Lifecycle: Following iOS 26, any UIKit app built with the latest SDK will be required to use the UI Scene lifecycle. This means that the traditional app lifecycle methods are deprecated, and you must adopt the UI Scene lifecycle to ensure your app launches correctly. You can learn more about this in the session What’s new in UIKit.

2. OpenURL Method: The existing Open URL method now accepts file URLs, allowing your app to hand off documents that are not natively supported. If a default app exists for the file type, the system will launch it and pass along your URL. This is detailed in the session What’s new in UIKit.

3. UI Requires Fullscreen: The UIRequiresFullScreen key is deprecated and will be ignored in future releases. Apps should be adaptable and remove this key to ensure flexibility. This is discussed in the session Make your UIKit app more flexible.

4. SwiftUI and UIKit Integration: iOS 26 allows mixing SwiftUI and UIKit scene types in a single app, which can enhance the flexibility and adaptability of your app. More details can be found in the session Make your UIKit app more flexible.

These changes are part of Apple's ongoing efforts to modernize app development and improve user experience across their platforms. Make sure to review these updates and adjust your app accordingly to take full advantage of the new features and requirements in iOS 26.
