OSC Send from an external Cocoa application

I'd like to send information from an external Cocoa application to my composition, perhaps into the OSC Receive patch. Is there a framework that would make doing this easy? I'm just getting started with Cocoa getting this to work, even with the help of a framework, will be a work in progress.

OSC send is nice because it sends structures, but I'd settle or anything that has a readily available framework or an example xcode project.

Thanks!
