I didn't find any contact information on the general Sparrow website so ill place it here. I have spend some time in creating a Xcode project template and file template which could be convenient for people to use.
It is very easy to setup and could provide some help when you want to create a new project including the Sparrow framework. It is based on the Scaffold project and thus familiar to people who are already using this.
It doesn't include the Sparrow code itself but links to it, in this way it is easy to make the templates compliant with feature releases of the Sparrow framework.
I would like to donate the templates (when there is interest for it) to the developers of the Sparrow framework, i think it can help you to leverage the professionalization of the framework even more.
It could still use a convenient installer which makes it even more accessible but currently it only involves three steps to set it up so it is already quite simple to use.
The templates can be found here along with the explanation on how to use them:
Please let me now when you are interested or have any questions.
