What's special about this is the use of GitHub. That has so much potential to improve the learning process. I hope the author will look beyond mere hosting of his sample code to actually showing how to use GitHub to tap a vast community of real working projects to learn from and use. In fact I bet if you reworked it as "Learning iOS Using GitHub" and pitched it to a publisher they might bite.
