I've been using Xcode 4.3.1 since it came out now and I've worked on many different projects since. Everything has always worked fine until this new project I'm working on.
The code completion/code sense never finds anything. When I 'Command+Click' a variable or class normally it would jump to that but now I'm just getting:
Symbol Not Found
The Jump to Definition action is not working.
If I open one of my older project while this bad one is open, the old ones still work for code sense and the new one doesn't.
My partner is working on the same project, we both get the files from our repository and the code sense works on his machine for this project...just not mine.
