I was planning to start a thread on this and here you go... I m glad someone else did. I am a programmer by profession but new to Xcode and Objective C. I have just started looking into the Framework and UIKit of Cocoa. Objective C doesn't seems like any different than any other objective oriented programming languages like java and C++.  I have just started on this so I won't be of much help to you guys but as time progress we might be able to share ideas. I will be in touch with you guys. However there are lot of forums out there which provides a lot of insides on app development.
