我一直在尝试让xcodebuild测试在使用Jenkins的远程计算机上工作。我遇到了无法通过SSH启动GUI的错误，并通过JNLP从站启动从属设备来解决它，如下所示：
通过SSH在Xcode6下运行xcodebuild测试时超时。现在我收到一个新错误：

错误域= IDEUnitTestsOperationsObserverErrorDomain代码= 3“由于等待测试过程中的登录超时而正在取消测试…”

无论是在终端机上还是通过Jenkins成功构建并运行测试，我都会遇到这些错误：

iPhoneSimulator：SimVerifier返回：错误域= NSPOSIXErrorDomain代码= 53“模拟器验证失败。”
{NSLocalizedFailureReason
=无法建立到模拟器验证服务的连接。NSLocalizedRecoverySuggestion=确保Xcode.app安装在启用所有权的卷上。NSLocalizedDescription=模拟器验证失败。}

iPhoneSimulator：无法连接到“ com.apple.instruments.deviceservice.lockdown”（错误域=
com.apple.CoreSimulator.SimError代码= 146“无法在当前状态下查找：关机”

我已经确保在安装XCode的地方启用了所有权，已经在模拟器上重置了内容和设置，并且已将plist文件移动到/ Library /LaunchAgents中。我已经尝试使用Google搜索这些错误，但找不到与我的问题有关的任何内容。还有其他建议吗？

其他信息：

XCode版本6.2（6C131e）
