Question

我已经提交了radar，因为我认为这是一个错误，但我想知道是否有人可以在此期间建议解决方案。

在安装了Xcode的计算机上成功运行数周后，测试将不再执行。似乎Xcode无法再找到模拟器或其设备。从Xcode中的Devices菜单（以及~/Library/Developer/CoreSimulator/Devices中的所有目录）删除模拟器设备并再次添加它们无济于事。

模拟器无法启动，Xcode中不会输出任何错误消息。在Console.app中打开system.log会显示以下消息：

不建议删除〜/ Library / Developer / CoreSimulator / Devices中的设备，因为您可能正在运行时从CoreSimulatorService下删除状态。我建议你通过以下方式“清理”：

使用sim
终止服务：killall -9 com.apple.CoreSimulator.CoreSimulatorService
删除状态：rm -rf ~/Library/*/CoreSimulator

这应该让你回到一个香草州。

如果这不能完全解决您的问题，请在重现问题后使用〜/ Library / Logs / CoreSimulator / CoreSimulator.log更新您的问题。请注意，您应首先启用调试日志记录：

defaults write com.apple.iphonesimulator DebugLogging -bool YES
defaults write com.apple.CoreSimulator DebugLogging -bool YES

Xcode 6无法找到模拟器设备并超时
