Before creating a project of your own, you should make some preparations in Xcode.
Sparrow is linked to your application via Xcode project references. This has the advantage that it’s easy to update Sparrow (just download a new release and overwrite the old one in the same directory) and that you can easily step into Sparrow source code, in case you want to do so.
This has to be done only once:
SPARROW_SRC
and let it point to /path_to_sparrow/sparrow/src/

and let it point to /path_to_sparrow/sparrow/src/
