Xamarin.iOS錯誤：未安裝Apple iOS SDK。 （iOS9，XCode 7 Beta）

Question

我已經在Mac OSX 10.10.5上安裝了XCode 7 beta，Xamarin.iOS 8.99.4和Xamarin Studio 5.9。

我參考這篇文章。 https://developer.xamarin.com/guides/ios/platform_features/introduction_to_ios9/ 。

如果我在iOS Simulator（iOS9）上調試/運行Xamarin.iOS應用程序，它將很好地工作。

但是，當我在iPhone5s設備（iOS9）上調試/運行它時，Xamarin會顯示此錯誤消息。

/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/iOS/Xamarin.iOS.Common.targets: Error: The Apple iOS SDK is not installed. (ex33.iOS)

“ Build Output”窗口顯示以下消息。

我能做什么？

PS當我在XCode 7 beta中調試/運行一個應用程序時，它在我的iPhone上運行良好。

檢查Xamarin Studio中的首選項。您可能需要更改Apple SDK路徑以指向Beta位置。

默認情況下，它應該在默認位置查找，但是只有在您同時安裝了通用發行版（非Beta版）Xcode和iOS SDK的情況下，它才會出現。
