Creative Selection, by Ken Kocienda, describes his experience working at Apple from when he was one of the first three people working on Safari and WebKit through working on the initial iPhone keyboard. A lot of good anecdotes and stories about the work and the people and how they develop software. And meanwhile he structures it around the principles of why their software methodology, which is not really a methodology but more like principal ideals, works and ends with the five to seven principle ideals that he thinks are key to software development at Apple.

It's a very readable book and the stories are interesting. Not a long read even though it's about 250-odd pages it's not dense. Also a good amount of drawn art that goes with the text. Also a generally upbeat book with nice insights on Scott Forstall and Steve Jobs.
