I've been getting this error since I upgraded to OSX 10.9 Mavericks. Can anyone tell me what is happening? The app doesn't crash but I get this annoying error everytime I compile. Is there a way to fix this?

I have had the same issue after upgrading to Mavericks. Just update your Xcode and the errors will go away.
