Question

我已升级到Xcode 9，iOS模拟器10.3和11无效。所有股票和我的应用程序都在试图运行时强行关闭。

当我尝试运行日历，首选项等时，

Xcode Console错误如下所示。＆＃34;无法获得有效的进程句柄＆＃34;意思？

Unable to find framework using path: /System/Library/Frameworks/VideoSubscriberAccount.framework

我已经在iOS 11 / 10.3.1的iPhone X，iPhone 8/8 +和iPhone 6+模拟器上试用了它，所有这些都具有相同的崩溃结果。如果我在较旧的iOS模拟器（如iPhone 6+ iOS 9.2）上试用它，那么它运行正常。

如果我尝试多次启动它，即Safari或日历的40-50次，有时特定的应用程序可能会运行，并且一旦成功运行，它将保持如此其余的会话（直到我在任务切换器关闭应用程序，然后同样的问题再次出现）。我的Xcode编译应用程序也是如此。

我的iMac 2009一直在运行El Capitan和Xcode 8，我刚刚使用Xcode 9升级到High Sierra。

我尝试过Xcode 9.1 Beta，但同样的问题仍然存在。

请帮助，谢谢。

感谢@ russbishop关于禁用第三方内核扩展的建议，我找到了罪魁祸首 - One Periodic's Hands Off Firewall！

我用这个命令卸载了kext：

func someFunc(_ values: [Float]) {
    for value in values {
        //we need to make that value mutable. You can use inout to make parameters mutable, or use vars in "for in" statement
        var unsafeValue = value
        //then put that value to the C function using "&"
        someCFunc(value: &unsafeValue)
    }

}

立即iOS模拟器中的所有股票应用程序都可以完美地启动。请注意，您必须卸载 kext。简单地禁用Hands Off中的规则并不能解决问题。

然而，我不能＆＃34; kextload ＆＃34;完成重新激活防火墙后，请关闭Hands Off驱动程序。需要重启系统。

我已经向Hands Off报告了这个问题，希望在下一个版本中看到修复。
