Could you explain the role and purpose of SceneDelegate in iOS applications?

SceneDelegate in iOS is responsible for managing the lifecycle of a specific scene (window) of the application. Starting from iOS 13, applications can support multiple windows (scenes), and SceneDelegate allows handling events related to each of them separately.

Main tasks of SceneDelegate:

• Creating and configuring the UI for a specific scene.
• Handling scene state transitions (active, paused, background, etc.).
• Managing resources associated with a specific scene.

This enables applications to better manage multitasking and support multiple windows simultaneously, for example, on iPad.

Example method in SceneDelegate:

func sceneDidBecomeActive(_ scene: UIScene) {
    // The scene became active, tasks can be resumed
}
