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

Open your Xcode project: Start by opening your existing project in Xcode.
Add a new file: Go to the File menu, select "New" and then "File..." to create a new file.
Choose the template: In the template chooser, select "iOS" and then "Source". Choose "Cocoa Touch Class" and click "Next".
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.
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.
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.
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.

For more detailed guidance, you might want to refer to the session on Xcode essentials which covers tricks for creating new files and managing your project structure effectively.
