使用未声明的类型 "ViewController"

Question

我正在使用 Tap Bar 控制器的库，因此我必须将 class 控制器的名称更改为 RAMAnimatedTabBarController 才能使用这些功能。但是在应用程序委托中，当我想显示主栏时，它会显示此错误

Use of undeclared type "RAMAnimatedTabBarController"

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {



    if UserDataSingleton.sharedDataContainer.logged == "logged" {


        let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        let initialViewControlleripad : UIViewController = mainStoryboardIpad.instantiateViewController(withIdentifier: "Order") as! RAMAnimatedTabBarController // error here 
        self.window = UIWindow(frame: UIScreen.main.bounds)
        self.window?.rootViewController = initialViewControlleripad
        self.window?.makeKeyAndVisible()

    }else{
        let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        let initialViewControlleripad : UIViewController = mainStoryboardIpad.instantiateViewController(withIdentifier: "loginViewController") as! loginViewController
        self.window = UIWindow(frame: UIScreen.main.bounds)
        self.window?.rootViewController = initialViewControlleripad
        self.window?.makeKeyAndVisible()

    }
