THANK YOU. This gave me my first actually working mac program. I had been having a bugger of a time doing it because all hte tutorials are using a different version of Xcode, but this tutorial + a little google on what's changed, plus a littl eplaying around and it worked. I really appreciate it mate!

Great tutorial, it was comprehensive and to the point.

I have very little experience in computer programming, but I wanted to get Xcode and learn Objective C. Are there any tutorial sites or books you would recommend to help me? Some people say to start with regular C code then move on to objective C, so I 'll probably go down that route.

Any advice is appreciated.
