What is the role of the SceneDelegate class in the application lifecycle?

The SceneDelegate class 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 handles events related to each of them, such as creation, activation, deactivation, and destruction of the scene.

Main tasks of SceneDelegate:

• Setting up the interface when a scene connects (method scene(_:willConnectTo:options:)).
• Tracking scene transitions to active, inactive, or background states.
• Managing resources associated with a specific scene.

Thus, SceneDelegate complements AppDelegate, which now handles global application events, while SceneDelegate manages events for a specific window.
