当路径不正确或试图获取文件夹的内容而不是路径时，也会出现此错误。

我有类似的问题(xCode 6.2)的示例代码下载。我试图在信息中将可执行名称设置为默认。但是这并没有起作用。

相反，将Compiler for C/ c++ /Objective-C更改为Default Compiler(Apple LLVM 6.0)，而不是Unsupported Compiler(com.apple.compilers.llvmgcc42) for project。

What we didn't do right was to not apply with the accurate code when signing in the Build Settings. We fixed the issue up this way: Enter into Build Settings >> Code Signing >> Code Sign Identity. Then, apply with your iOS Developer ID for 'Debug', but be sure to apply with your iOS Distribution Profile for 'Release' We didn't apply correctly, so we couldn't have permission to ask for the App from the server, actually. Anyway this post forced us to revise all the parameters and requirements, so we pretty appreciate all your answers. Regards, T.

有时候在新版本的Xcode中打开旧项目会得到这个消息。

转到问题导航器，并遵循警告提示“更新到重新确认的设置”。

繁荣,神奇!

在Xcode中执行以下操作

窗口->组织者->项目->应用程序的问题->删除按钮在派生数据。

然后我清理了项目，瞧

作品

我发现在Build Options中将我的编译器更改为LLVM 6.0对我来说就足够了(xcode 6.1)
