I decided to do an app instead of a game for a change, just to see what the interface builder, XML and "work" type development would be like. It turned out being a lot faster and simpler than I expected. I have also always been a big fan of BOINC, and checking my "stats" for many years now, all the way back before there was a BOINC platform, and it was only the SETI@Home project.
(An added bonus: unlike games this one it would actually be available on the South African App store as well as the international ones)
During my development career I have never really spent a lot of time designing and developing UIs, I always ended up on the backend side of development projects. So take the next statement in that light:
I think Apple has actually done a pretty good job (after some initial learning frustration) with their interface builder and storyboard shipped with XCode. I sat down and after a good couple of hours of struggling, something eventually clicked and it all finally came together. I restarted my project, copied over the backend code and in literally 15 minutes the storyboard and 3 UIs were done. Awesome.
I had a couple "funnies" while still using XCode 4.2, but just upgraded to 4.3 and those particular issues seem to have been corrected.
