I'm confused, I thought a Cocoa library was a number of *.o (compiled .m files) archived into a single file with a transfer vector table at the front.
Yes… and this is one of the .m files that will make up your library. It sounds like you are getting the library and the source files mixed up? (For one thing, the source files don’t have to be named “libaaa”. You can rename them whatever you want if that’s clearer to you.)

Just because that’s what’s in the template for this project type. Don’t worry about it. If you don’t want to put a class in there, just erase what Xcode put in.
