Xamarin VS 2017無法渲染iOS故事板文檔

我在一個窗口中啓動了VS 2017中的新Xamarin跨平臺項目。 Android部分工作正常，但是當我嘗試打開iOS Main.Storyboard文件時，出現錯誤。我連接到有xcode 8.3的mac。Xamarin VS 2017無法渲染iOS故事板文檔

Xamarin.iOS版本的VS窗口 - 在VS 2017年社區10.4.0.123

Xamarin的iOS版本在Mac上 - 10.12.0.18

我再也找不到比降級的Xcode其他任何答案。我認爲這個問題可能與Xamarion.iOS版本不匹配，但我無法弄清楚如何解決這個問題。任何幫助是極大的讚賞！！

編輯解決方案

對於有同樣的問題的人，安裝Xamarin更新擴展VS &更新Xamarin蘋果SDK固定爲我這個問題。按照步驟here。

更新到最新版本修復了它。

另外，在Windows上使用Visual Studio 2017時，我遇到了同樣的問題。升級Xamarin（mac上的穩定頻道&窗口）並更新Visual Studio 2017到最新版本（15.0.26228.12）爲我解決了它。

雖然我沒有看到升級xamarin的方法。文檔只是告訴你更新Visual Studio（我做過）.https：//developer.xamarin.com/guides/ios/getting_started/installation/windows/ – jdoyle1331

我最好這個問題的建議是NEVER使用IOS designer。這是垃圾。始終使用Xcode Interface Builder。主要原因是，你保證故事板將在IOS中有效。我曾經在IOS Designer中創建了一個空的故事板，並將它生成的XML與在Xcode中創建的空故事板進行了比較。它完全不同。設計師版本錯過了許多信息。從那以後，我從來不信任IOS設計師。不僅如此，在iOS設計器上使用約束是一種痛苦，因此在Xcode中它們更容易。如果佈局非常複雜，我也會在IOS設計器中使用故事板渲染完全錯誤。
