Xamarin.iOS应用程序无法在模拟器上运行（可能在上次Xamarin.iOS更新之后）

iOS应用程序没有在iPhone模拟器中启动（使用iPhone 5-iOS 10.0）。 日志中有错误

CoreSimulator.log

：

mlaunch[1482] <Error>: Error Domain=FBSOpenApplicationServiceErrorDomain Code=1 "The request to open "com.xamarin.acquaint-native" failed." UserInfo={NSLocalizedDescription=The request to open "com.xamarin.acquaint-native" failed., BSErrorCodeDescription=RequestDenied, NSUnderlyingError=0x7fe15ceb7540 {Error Domain=FBSOpenApplicationErrorDomain Code=1 "(null)" UserInfo={BSErrorCodeDescription=Unspecified}}, NSLocalizedFailureReason=The request was denied by service delegate (SBMainWorkspace) for reason: Unspecified.}

上面的日志用于熟悉预构建应用程序。我尝试了其他几个应用程序，同样的故事。 它过去工作得很好。

---

我正在使用最新的Xamarin iOS SDK更新（这可能就是问题所在）

您有最新版本的Xcode吗？

---

除非在Mac工作站上安装了Xcode 8.2（或8.1，不确定），否则无法在IOs 10上进行模拟。

在新项目和最新Xamarin中遇到了同样的问题。

---

为了修复它，我不得不在项目选项中将“支持的体系结构”更改为“i386”。默认值是“x86_64”。

我试图从项目的模板创建单视图应用程序。同样的问题。在我更新Xamarin.iOS SDK/xCode之前，一切都正常。。。。这可能没有关系，但这是我对我的开发环境所做的唯一修改。你下载了模拟器吗？
