Xcode 8 Beta（null）无法为请求提供服务 [英] Xcode 8 Beta (null) was unable to service the request

问题描述

我有一个在Xcode的发布版本中运行良好的应用程序。我下载了测试版，在我修复了所有的小改动后，我运行它并且它有效。我刚刚回来再次运行它我得到一个错误说

I have an app that worked fine in the released version of Xcode. I downloaded the beta and after I fixed all the little changes I ran it and it worked. I just came back and ran it again and I get an error saying

打开com.matthewhsingleton.Smoke的请求失败。 （null）无法为请求提供服务。

The request to open "com.matthewhsingleton.Smoke" failed . (null) was unable to service the request.

我已经退出Xcode并重新打开它，我重新启动了我的计算机，尝试了不同的iPhone模拟器并且都生成了相同的结果

I have quit Xcode and reopened it, I have restarted my computer, tried different iPhone simulators and all produce the same resulte

推荐答案

阅读@Droppy建议后，我读了线程，这是一个常见的问题。解决方法如下：

After reading @Droppy suggestion I read the thread and it is a common issue. To solve it is as follows

实验室中的Apple工程师解决了问题。这是他们正在努力的问题。最重要的是，当我将Xcode复制到Applications文件夹时，它上面有一点设置，这阻止了它与模拟器的通信。

Problem solved for by an Apple Engineer in the lab. It's an issue they're working on. The bottom line was that when I copied Xcode to Applications folder, there was a bit set on it and that was preventing it from communicating with the simulator.

要修复它：
将Xcode-beta.app从Applications文件夹复制粘贴到其他地方，例如文件夹。
从Applications文件夹中删除Xcode-beta.app。
再次将Xcode-beta.app从Documents移至Applications文件夹。

To fix it: Copy-paste Xcode-beta.app from Applications folder to somewhere else, e.g. Documents folder. Delete Xcode-beta.app from Applications folder. Move Xcode-beta.app from Documents to Applications folder again.
