我买了一台新的 MacBook Pro 来开发一个 iOS 通用应用程序。在我卖掉旧的之前，我将我的代码推送到一个 BitBucket 存储库。
现在我已经安装了 VS for Mac 和 Xamarin Studio，并从 bitbucket 中提取了源代码。一切正常(构建、调试等)，但在 Storyboard 设计器中进行设计无法正常工作。
我遇到以下异常:

根据异常，我的 xml( Storyboard)无效，无法解析。我以某种方式能够在我的旧 MacBook(6 个月前)上打开 Storyboard。也可以通过 XCode Interface Builder 打开 Storyboard。

关于如何解决这个问题有什么建议吗？我真的不想开始重新设计我的应用程序。
谢谢!
