HOORAY! It works!
Got my app running on the IPad simulator on the mac. Blimey, there are lots of options. Finally got it to work using a combination of Ancient Lady's tutorial and the info on TGC's site.
After the build, XCode has 15 warnings. Should I worry about these or shut my eyes and look the other way?
At the moment, the plan is to get my app somewhere near finished (it's a simple one, and I'm about half way there), then sign up for a dev account with Apple so that I can test it on the IPad itself.
Cheers,
James
