I just finished reading the objective-c developer handbook from apple. So I pretty much know everything that there is to know about objective-c (hee hee hee). I was wondering how do I go about designing a 3-tier application in objective-c. The 3-tiers being a front-end application in Cocoa, a middle-tier in pure objective-c and a back-end (data access also in objective-c and mysql db).
I'm not really interested in discussing why I'd need a 3-tier architecture, I'd like to narrow the discussion to the 'how'.
For example, can I have 3 separate x-code projects one for each tier? If so how would I link the projects together. In java, I can export each tier as a jar file and form the proper associations.
