Would not recommending setting the entire application in a waiting state. If the application needs to do more work before finishing the watchdog could kill the application for taking too long time to start up.

Instead you could do something like this to delay the launch screen.

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        window = UIWindow(frame: UIScreen.main.bounds)
        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()
        }
        return true
    }
