How to add sceneDelegate to the current Xcode Project?

To add a sceneDelegate to your current Xcode project, you can follow these general steps:

1. Open your Xcode project: Start by opening your existing project in Xcode.

2. Add a new file: Go to the File menu, select "New" and then "File..." to create a new file.

3. Choose the template: In the template chooser, select "iOS" and then "Source". Choose "Cocoa Touch Class" and click "Next".

4. Configure the new class: Name your class something like SceneDelegate and make sure it's a subclass of UIResponder and conforms to the UIWindowSceneDelegate protocol. Click "Next" and then "Create" to add the file to your project.

5. Implement the SceneDelegate methods: In your new SceneDelegate class, implement the necessary methods to manage your app's scenes. This typically includes methods like scene(_:willConnectTo:options:), sceneDidDisconnect(_:), sceneDidBecomeActive(_:), etc.

6. Update your Info.plist: Ensure that your Info.plist file is configured to use the SceneDelegate. This usually involves setting the UIApplicationSceneManifest key with appropriate sub-keys to specify your SceneDelegate class.

7. Modify your AppDelegate: If your project was initially set up without a SceneDelegate, you might need to adjust your AppDelegate to work with scenes. This often involves removing or modifying methods related to the app lifecycle that are now handled by the SceneDelegate.
