Renaming a project in Xcode, I cannot rename anymore and it crashes

I tried to rename my project in xcode, but when I tried to go to a second view controller, everything crashed. So, I tried to rename it one more time. But now I am really stuck...

It is now saying that it is running 'myNewName.temp_caseinsensitive_rename' on iPhone and still everything crashes when I go to the second view controller. But now, I cannot change it. Everytime I change it, the '.temp_caseinsensitive_rename' is still there... Crap, What should I do! I am really lost now...

I am using xcode 6.2 on Mavericks.
