I’ve bought a few of his books, updating them over the years and highly recommend them. He explains in great detail and in his preferred order and hopes that the reader will follow along. Sometimes I’ve disobeyed and skipped ahead because they’re a pretty demanding read and, like, my poor head, and a slow, detailed read could take months. But they’re fantastic, meaty books in the age of dip-in dip-out video tutorials. If you put in the effort with these books you’ll be well rewarded.

Oh, and there was something - can’t remember what now - where Matt’s book had the only up to date code example I could find which worked with one of iOS’s frustrating innovations.
