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 Der

Answer 1

Clearing the "Derived Data" only works temporarily for me. I have to do it and then restart Xcode like 3-4 times each day to get code sense working again.

I found out the real cause is in the Target's Build Settings. I moved everything from Header Search Paths to User Header Search Paths and it is fixed. In my case, the framework I'm working with is RestKit.

BTW, I came up with this because I was adding another project (QuickDialog) into my project and I was curious that it is using User Header Search Paths, but not Header Search Paths. Here is the difference between them.
