ios - 在 API 中创建 if 条件时，如何修复 swift 代码中调用 Storyboard 的速度？

Question

我有一个API，可以检查用户名和密码是否正确，当正确返回值“1”CHK =“1”时，调用并检查值时，我用消息打印控制台，当我单击它时，消息很快就会出现但切换到主页 Storyboard需要时间，有时甚至不起作用。

if let url = urlString {
        let task = URLSession.shared.dataTask(with: url) { (data,        response, error) in
            if  let error = error {
                print(error)
            } else {
                if let unwrappedData = data {

                    do{
                        //let dataString = NSString(data: unwrappedData, encoding: String.Encoding.utf8.rawValue)!
                        let json = try JSONSerialization.jsonObject(with: unwrappedData, options: []) as AnyObject

                        if let JsonDic = json[0] as? NSDictionary
                        {
                            if let check = JsonDic["CHK"] {
                                if let check1 = check as? String {
                                    if check1 == "1" {
                                        let HomeViewControler = self.storyboard?.instantiateViewController(withIdentifier: "HomeViewController") as! HomeViewController
                                        self.navigationController?.pushViewController(HomeViewControler, animated: true)
                                        self.dismiss(animated: false, completion: nil)
                                        print("You Are ready to login")
                                    }else{
                                        print("You Enterd a wrong password or Mail")
                                    }
                                }
                            }
                        }

                    }catch{
                        print("There are an Error")
                    }

删除self.dismiss(animated: false, completion: nil)并更新代码

  if check1 == "1" 
   {
      let HomeViewControler = UIStoryboard.init(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "HomeViewController") as! HomeViewController
      self.navigationController?.pushViewController(HomeViewControler, animated: true)       
      print("You Are ready to login")
   }
