Often with a new technology, the first books are just retreads of the official docs for years until developers dig into the APIs. With Jeff Kelley having taken that step for us already by working on some of the first shipping WatchKit apps, we get a huge head start. His book is deeply rooted in hard-won lessons about what actually works on Apple Watch, and he shows how to make apps that can really shine on this new platform.

This is an essential book for any iOS developer interested in getting started with WatchKit. It starts you off with a detailed summary of all of the Apple Watch features and capabilities, and then progresses along a logical path to advanced concepts and performance strategies. Working through each chapter, I started to develop several potential app and app-compliment ideas. I’ll be referring to this book often in the near future.

Apple Watch development is new and evolving territory, and this book covers all the bases. If you want to tackle watchOS development, the information you need to fire on all pistons is right here.
