When I navigate to:
当我导航到：

Does anybody know how I can resolve this? I cannot delete anything at the directory as suggested in the 2nd part of the error message as that directory doesn't exist!

Had same problem. Clearing derived data folder solved the issue for me. In Xcode, go to Window->Organizer->Projects, select your project, and press the "Delete..." button next to "Derived data".
有同样的问题。清除派生数据文件夹为我解决了这个问题。在 Xcode 中，转到 Window->Organizer->Projects，选择您的项目，然后按“Derived data”旁边的“Delete...”按钮。
If this doesn't work, you can try to do a Product->Clean (Cmd+Shift+k).
如果这不起作用，您可以尝试执行 Product->Clean ( Cmd+ Shift+ k)。

By default Library folder is hidden in Mac. Best way to navigate to that folder is :
默认情况下，库文件夹在 Mac 中是隐藏的。导航到该文件夹的最佳方法是：
- Open Finder
- Select Go from menu -> Select "Go to folder"
- Type : /Users/"your user name"/Library/Developer/xcode
- 打开查找器
- 从菜单中选择 Go -> 选择“Go to folder”
- 输入：/Users/“你的用户名”/Library/Developer/xcode
This will open direct xcode folder inside hidden library folder.
这将打开隐藏库文件夹中的直接 xcode 文件夹。
- Select "DerivedData" folder
- Command + A, select all and delete them.
- Open Simulator and "Reset Content and Settings".
- 选择“DerivedData”文件夹
- Command + A，全选并删除它们。
- 打开模拟器和“重置内容和设置”。
Now run XCode again, all will fix.
现在再次运行 XCode，一切都会解决。

In my case, I accidentally modified NSURLConnection.h. Xcode complained about cache at path
就我而言，我不小心修改了 NSURLConnection.h。Xcode 抱怨路径缓存

I finally found the steps to fix it:
我终于找到了修复它的步骤：
- Quit Xcode
- Delete the upper "5.0.2-5A3005" at /var/folders/p6/fk2rmf017sn2d_gds6dtqr6hrst8b2/C/com.apple.DeveloperTools/5.0.2-5A3005
- 退出 Xcode
- 删除 /var/folders/p6/fk2rmf017sn2d_gds6dtqr6hrst8b2/C/com.apple.DeveloperTools/5.0.2-5A3005 上的“5.0.2-5A3005”
When Xcode restarted, it regenerated that folder and everything in it.
当 Xcode 重新启动时，它会重新生成该文件夹及其中的所有内容。

I got same error on executing xcodebuild command of Xcode6-beta5.app coexisting with Xcode.app (Xcode 5).
我在执行与 Xcode.app (Xcode 5) 共存的 Xcode6-beta5.app 的 xcodebuild 命令时遇到了同样的错误。
In this case I added -derivedDataPathto separate ModuleCache from the one for default Xcode.app.
在这种情况下，我添加-derivedDataPath了将 ModuleCache 与默认 Xcode.app 分开的模块。
xcodebuild -derivedDataPath ./build/Xcode6-beta5/DerivedData ....
This works for me.
这对我有用。

I tried deleting derived data and Clean project several times and it doesn't work. The file in my warning is an old file I already deleted from Project Navigator and all the Build Settings. But it keeps showing up and gives me this error. The error only occurs on Simulator, but not on device. Which is really really weird. :/
我多次尝试删除派生数据和清理项目，但它不起作用。我的警告中的文件是我已经从项目导航器和所有构建设置中删除的旧文件。但它一直出现并给我这个错误。该错误仅发生在模拟器上，而不发生在设备上。这真的很奇怪。：/
For some reason, I switched branch to some other branch and switch backand it works again. If anyone even know how that could work please tell me :D
出于某种原因，我将分支切换到其他分支并切换回来，它再次工作。如果有人知道那是如何工作的，请告诉我：D
