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

I solved this by:

Quit restart Xcode + clean project + clean build folders + clean derived data + deleted the /var/folders/.../.../C/com.apple.DeveloperTools/5.0.2-5A3005/Xcode/SharedPrecompiledHeaders + unplugged my iPhone

Rebuild and works :)
