XCode 4 adding framework problem

[dbarrett]

I'm updating an older app with some new functionality and I'm having some issues with the framework.

I believe I added the MapKit.framework correctly, however here are the issues I'm seeing:

1) When I start typing "#import <MapKit/MapKit.h>" in the header, it WILL NOT autocomplete. It's like it hasn't been added... although it has.

2) Building the app fails with a 'Apple Mach-O Linker' error.

Is there some type of magical steps I need to take to get this old app to recognize I've added a new framework?

Thanks.
