Swift 5.x, iOS 13.x.x

Modifying the following function in the AppDelegate class does not work in Swift 5.x/iOS 13.x.x.

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

Instead, you will have to modify the scene function in SceneDelegate class as following. It will delay the LaunchSceen for 3 seconds.

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {

    window?.rootViewController = UIStoryboard(name: "LaunchScreen", bundle: nil).instantiateInitialViewController()
    window?.makeKeyAndVisible()

    DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 3) {
        self.window?.rootViewController = UIStoryboard(name: "Main", bundle: nil).instantiateInitialViewController()
    }

    guard let _ = (scene as? UIWindowScene) else { return }
}

The window variable should already be there in SceneDelegate class like the following.

var window: UIWindow?
