Question

当我想为iOS运行UI测试时，会收到以下消息：

SetUp : System.Exception : Unable to determine simulator version for X

堆栈跟踪：

当我在Android上运行相同测试时，所有功能都像魅力一样。这是在我将xcode 10.2降级到10.1时发生的，因此可能是某些地方损坏了。但是，奇怪的是我可以毫无问题地调试我的iOS应用程序。

预先感谢

Answer 1

此问题的原因是Xcode 10.2对Xamarin.UITest能够与本地iOS模拟器进行连接的方式进行了更改；恢复兼容性之前，必须先更新Xamarin.UITest。根据我在重现问题时的观察，即使您降级到Xcode 10.1，iOS模拟器似乎仍然保留了Xcode 10.2应用的某些设置，因此继续阻止测试。

尚不支持Xcode 10.2的Xamarin.UITest的当前版本，尽管我怀疑它将在下一个版本中发布。（在撰写本文时，最新版本是2.2.7.28-dev）

以前在其他Xcode更新中也发生过这种情况：

“ [iOS] Xcode 10.1集成：固定的默认模拟器选择” Xamarin.UITest 2.2.7
“ [iOS]提供对Xcode 10的支持” Xamarin.UITest 2.2.6
“ [iOS]提供对Xcode 10 beta 6的支持” Xamarin.UITest 2.2.5.1806-dev
“ [iOS] Xcode 9.4.1支持” Xamarin.UITest 2.2.5
“ [iOS]支持Xcode 9.3和iOS 11.3” Xamarin.UITest 2.2.4
等等

Answer 2

将Xamarin.UITest更新为3.0.7，为我解决了该问题

UI测试，无法运行iOS ui测试-无法确定X
