xcode4 - Xcode 4 code sense is not working

Question

I am running a "old" Xcode 3 project in Xcode 4 and code sense is not working for my own classes. I have tried following:

• Clean/rebuild
• Remove Derived Data
• Installing 4.3 documentation
• Restart

Without any luck.

Sometimes the code sense works but mostly I just get "No Completions".

Answer 1

Try this:

Open Organizer then Project Tab.

Clear the "Derived Data". Xcode should re-index your project then and code sense should work. At least worked for me.
