On line ten of this swift code I am getting a error I have asked ChatGpt and could not get a valid response that is why I reached out the the stack overflow community

import UIKit

@main
class AppDelegate: UIResponder, UIApplicationDelegate { //This is where I am getting the problem

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Customization after application launch
        return true
    }

    // MARK: - UISceneSession Lifecycle

    func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
        // Select a configuration to create the new scene with
        return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
    }

    func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
        // Release any resources specific to the discarded scenes
    }
}

I tried to use ChatGpt and it was still giving the error I put in the error into ChatGPT and it still did not give me the proper answer
