How do I use UIScene and multiple windows?

In iOS development, UIScene is a framework that allows your application to support multiple windows. This is particularly useful on iPad, where users can interact with multiple instances of your app simultaneously. To enable multiple window support, you need to configure your app to use scenes in the app's Info.plist and implement the necessary code in your AppDelegate or SceneDelegate.

Example of UIScene and Multiple Windows

// AppDelegate.swift import UIKit @main class AppDelegate: UIResponder, UIApplicationDelegate { // Your app delegate methods... } // SceneDelegate.swift class SceneDelegate: UIResponder, UIWindowSceneDelegate { var window: UIWindow? func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) { guard let windowScene = scene as? UIWindowScene else { return } window = UIWindow(windowScene: windowScene) window?.rootViewController = YourRootViewController() window?.makeKeyAndVisible() } func sceneDidDisconnect(_ scene: UIScene) { // Handle disconnect } func sceneDidBecomeActive(_ scene: UIScene) { // Handle activation } func sceneWillResignActive(_ scene: UIScene) { // Handle deactivation } func sceneWillEnterForeground(_ scene: UIScene) { // Handle transition from background to foreground } func sceneDidEnterBackground(_ scene: UIScene) { // Handle transition to background } }
