Preface

This book is for developers who already have a basic knowledge of developing with WatchKit and watchOS 2, and who are now interested in learning how to use them to create cutting-edge Watch apps. It is written by five experienced Apple Watch developers who have created their own apps early on, and will now show you how to best create your own Apple Watch apps.

The examples in this book use Objective-C and Swift version 1.2 and were tested with Xcode 6.3 and 6.4.

If you are just starting out in this space, be sure to pick up and read the Apress beginner’s book for Apple Watch development, “Learn WatchKit for iOS.” If you have already read that, or have already gotten your feet wet, then this book is for you.
