When I incorporated a popular OAuth2 library in iOS called OAuth2Client to my iOS app which is developed on Xcode 7 Beta 2 and then tried running the simulator, the following error occurred and the simulator didn't launch.
当我在iOS中把OAuth2Client (OAuth2Client)合并到我的iOS应用程序中，它是在Xcode 7 Beta 2上开发的，然后尝试运行模拟器，发生了以下错误，模拟器没有启动。
Unsupported compiler 'com.apple.compilers.llvm.clang.1_0' selected for architecture 'x86_64'
不受支持的编译器com.apple.compile .llvm.clang.1_0'选择架构'x86_64'
What does this error mean? A lot of warnings (yellow triangle) followed with the error above (red octagon), such as:
这个错误是什么意思?许多警告(黄色三角形)和上面的错误(红色八边形)，例如:
warning: no rule to process file '/Users/myUsername/myAppname/Pods/NXOAuth2Client/Sources/NSData+NXOAuth2.m' of type sourcecode.c.objc for architecture x86_64
警告:没有规则处理文件'/用户/myUsername/myAppname/ pod /NXOAuth2Client/ NSData+NXOAuth2。sourcecode.c m的类型。建筑objc x86_64
How can I deal with the these errors and run the simulator properly? Or does CocoaPods only work on environments prior to Xcode 7 Beta?
如何处理这些错误并正确运行模拟器?或者，CocoaPods只在Xcode 7 Beta之前工作?
UPDATE
Later I found that this occurs on any projects I create, not only on a project using CocoaPods. The only clue that occurs to me is that when I updated my iTunes to 12.2 today and then launched my Xcode, the dialog popped up, instructing to install new command-line tools.
后来我发现，这发生在我创建的任何项目上，而不仅仅是在一个使用CocoaPods的项目上。我唯一的线索是，当我今天更新我的iTunes到12.2，然后启动我的Xcode时，对话框弹出，指示安装新的命令行工具。
UPDATE 2
I just upgrade to Xcode 7 Beta 3 but the error still got me annoyed...
我只是升级到Xcode 7 Beta 3，但是这个错误还是让我很恼火……

I met the same issue on Xcode 7 beta 4. I have tried to clean the project for several times but with no lucky. Unbelievably, restart Xcode saved my night. You can try this.
我在Xcode 7 beta 4上遇到了同样的问题。我曾多次试图清理这个项目，但没有成功。令人难以置信的是，重启Xcode拯救了我的夜晚。你可以试试这个。

Close Xcode, open terminal, before anything else, type: “defaults delete com.apple.dt.Xcode” (this addresses your Xcode settings) open Xcode and your project should work normally.
关闭Xcode，打开终端，在其他任何东西之前，键入:“default delete com.apple.dt。Xcode(这是您的Xcode设置)打开Xcode，您的项目应该正常工作。
Plan B
If that doesn't work try this to clear out your cache. Save your files then put this in your terminal:
rm -rf Library/Caches/com.apple.dt.Xcode/
如果这还不起作用，试着清除你的缓存。保存你的文件，然后把它放在你的终端:rm -rf库/缓存/com.苹果. dt.xcode /。
Potential causes
This bug can occur if you declared your pods with single quotes instead of double quotes or for some reason your pod files become corrupted (i.e.: working with p.lists, Google's p.list, firebase etc). I think what triggers the bug to break your code is during certain recompiling phases, for example: opening after unzipping the project, or opening the project after pulling it from GitHub.
如果你用单引号代替双引号或者由于某种原因你的pod文件被损坏了(例如::使用p。列表,谷歌的p。列表,重火力点等等)。我认为在某些重新编译阶段(例如:打开项目后打开，或者从GitHub中取出项目后打开项目)，会触发bug破坏您的代码。

With the version (X-code 8 beta 2) I got the following error, because I tried to run it out of the downloads folder:
有了这个版本(X-code 8 beta 2)，我得到了下面的错误，因为我试图从下载文件夹中运行它:
Unsupported compiler 'com.apple.compilers.llvm.clang.1_0' selected for architecture 'x86_64'
It helped to put it in the normal Program Folder!

Angel's answer worked for me as well. I too experienced this with 8b2, Moving the app to the Program folder instead running out of Downloads resolved it for me.
