A project I've been working for 2 months stopped working for no reason because Xcode got stucked on "Indexing". I can't Build the project anymore. If I try to build, Xcode freezes and I have to force quit. This happens only with this project.
I tried cleaning all derived data but didn't help.
I'm using Xcode 4.5.2.
Any ideas?
If your problem is not solved then replace the file with your backup file.
