Can't get rid of Apple LLVM 5.0 Error

Question

It keeps saying:

fatal error: file \'/Applications/Xcode5-DP5.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/includ

Answer 1

The same thing was occuring to me. The warning was telling me:

After modifying system headers, please delete the module cache at '/Users/yunus.mehel/Library/Developer/Xcode/DerivedData/ModuleCache/13XL2DHZVON89'

So, I have restarted xcode, deleted derived data from Organizer, deleted derived data from the derivedData folder; none of them worked. Then I have realized, the solution was already there; go to:

"DerivedData/ModuleCache/13XL6DH2BON89"

and delete that folder, not the "DerivedData/". Make a clean build, it will work again.
