macOS Duplicate Apple-Made Classes?!

[Blakeasd]

Today I opened up Xcode and ran my project, and I got 2 errors, here are the errors:
Duplicate interface definition for class 'CIColor'

The other error is:
'CoreImage/CIImage.h' file is not found

Any Ideas (Running Xcode 4.0)

Nevermind I just ran the project again and it worked
