Who’s This Book For?

Making an Apple Watch app, at least for now, means making an iPhone app to contain it. This book assumes some familiarity with making iPhone apps; you should know the basic concepts behind object-oriented programming and be able to follow along with code written in Swift for iOS. Many of the concepts in WatchKit are brand new to even the most experienced iOS developer, so don’t worry; I’ll explain the code we’re writing as we go along.

If you’ve never made an iOS app before and want to make an amazing iPhone app to go along with your amazing Apple Watch app, the Pragmatic Bookshelf has your back with iOS 9 SDK Development.^[1] If you’re just starting out, I highly recommend reading that book in addition to this one; many of the skills you learn in one will transfer to the other.
