Pods Project compiles in xcode; but not appcode

Anyone got any ideas? I've got a project which has a dependency to AFNetworking ine the podfile. Code completion is perfect in appcode, and intellisense works etc.

It compiles and builds fine in xcode.


Same workspace does NOT compile anymore in appcode. It looks like it doesn't find the AFNetworking library...

i.e.
Error:Undefined symbol '_OBJC_CLASS_$_AFHTTPRequestSerializer' referenced from:
Error:  objc-class-ref in GMWebMetadataLoader.o
Error:Undefined symbol '_OBJC_CLASS_$_AFJSONResponseSerializer' referenced from:
Error:  objc-class-ref in GMTwitterFeed.o
Error:  objc-class-ref in GMWebMetadataLoader.o
Error:Undefined symbol '_OBJC_CLASS_$_AFHTTPRequestOperation' referenced from:
Error:  objc-class-ref in GMTwitterFeed.o
Error:  objc-class-ref in GMWebMetadataLoader.o
clang

I've cleaned and rebuilt.. what can I possibly be missing? I presume that appcode must be cachign something in my workspace, as the pod depdencies all get compiled into one dll, right?

thanks.
