I'm so glad that Paul Hegarty is teaching this. Not only does he know the material through experience (I think he was an early employee at NeXT and continued on at Apple), he also explains things really well and works through lots of examples. It's also clear that he enjoys teaching the course, which makes a big difference. I watched an earlier iteration of the course, and it's the reason I know iOS development today. I don't often write reviews (and certainly not on HN), but I absolutely have to recommended this course for anyone interested in learning mobile development.
