Are you just getting started with Xcode and don’t know where to start ? Well, there are several resources on internet – Apple dev site, YouTube tutorials etc. You could learn programming lang more in a systematic manner or learn through experimentation. My advice would be to learn in a systematic manner as Objective-C is a little bit challenging language. It’s better to spend time before hand vs later on.

Here are some good resources to get you started:

• Stanford Class: Paul Hegarty a professor at Stanford made his class material available through iTunes. The material is excellent. You can download the material through iTunes. Slidedecks etc are available here.
• Apple Developer Site: The developer site also has good information. Just follow the link here.

Happy reading and good luck. If you have any questions feel free to drop a comment.
