在分析IOS时保存对象，网络连接失败

在完成快速入门解析教程之后，我尝试使用以下简单代码将一些数据保存到云：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    Parse.setApplicationId("MY APPLICATION ID", clientKey: "MY CLIENT KEY")      
    var gameScore = PFObject(className:"GameScore")
    gameScore["score"] = 1337
    gameScore.saveInBackgroundWithBlock {
        (success: Bool, error: NSError!) -> Void in
        if (success) {
            // The object has been saved.
        } else {
            // There was a problem, check error.description
        }
    }  
    return true
}

错误是：

我尝试了几个网络，因此这不是连接问题，我尝试重置/重新启动模拟器，但没有帮助。

显然，您的服务器不响应JSON，而是纯html文本。我如何处理它并使其工作？我想使用正确的URL。
