我想您正在尝试执行以下操作：

        let storyboard = UIStoryboard(name: "Main", bundle: nil)
                   if let user_id = UserDefaults.standard.value(forKey: "uid")
                   {
                       let homeViewController = storyboard.instantiateViewController(withIdentifier: "HomeTabBarCtrlr") as! UITabBarController

                        let nav = UINavigationController(rootViewController: homeViewController)
                       self.window!.rootViewController = nav
                   }else{
