Permission Denied on Xcode 4

问题:

I'm getting error message about permission denied, when I build any app on Xcode 4:

error: unable to create '/Users/mike/Library/Developer/Xcode/DerivedData/JewBack-ejcsrvhiqaxnzmdheqdhshjvwjng/Build/Products' (Permission denied)

There's other error message, too:

Ok. It seems you may be restricted to create Build Folder in your system. Try out below procedure which creates Build Folder in project folder itself.

In XCode Menu --> Preferences --> Locations Tab --> In Locations Change Derived Data to Relative and Give any name in text box. I have given Build. This folder will be created in your project folder for built binaries.

please check your Xcode version and upgrade your Xcode. early I was using Xcode 6.1 and I got error message with that Xcode version after then I upgrade Xcode Version 6.2. now It is working perfectly. when you upgrade your OS X version You should upgrade Xcode version.
