In my current project I am integrating RestKit library (I don't know if it matters), trying to deliver the app for testing when I use "Archive" the compiler complains
"RestKit/RestKit.h" is not found
while building and running the app (even on iPhones, not just the simulator) does not show any problem at all.
I had the same issue. It appears to be a bug or something in how Xcode handles static libraries and implicit dependencies. You can find several suggestions here: Compile, Build or Archive problems with Xcode 4 (and dependencies)
For me, step 3 on the answer was the solution. Also see step 8 on the answer here: How do you get implicit dependencies to work with workspaces in Xcode 4?
RestKit installation into your XCode 4 project should be uneventful (at least it was for me). However finding the proper up-to-date documentation on how to do it the right way wasn't exactly easy to find.
Check that you followed steps steps as described in these screenshots: https://github.com/RestKit/RestKit/tree/master/Docs/Images/Installation
