iOS应用程序无法在iPhone模拟器中启动(iPhone 5 – 使用的是iOS 10.0).

日志有错误

CoreSimulator.log：

mlaunch[1482] <Error>: Error Domain=FBSOpenApplicationServiceErrorDomain Code=1 "The request to open "com.xamarin.acquaint-native" failed."

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.
它曾经工作得很好.
我正在使用最新的Xamarin iOS SDK更新(可能是这个问题)

最佳答案 新项目和最新的Xamarin遇到了同样的问题.

为了解决这个问题,我不得不在项目选项中将“支持的架构”更改为“i386”.默认值为“x86_64”.
