This book is for intermediate iOS developers who already know the basics of iOS and Swift development but want to learn how to make Apple Watch apps for watchOS 4. Every single chapter in this book has been updated to Swift 4 to ensure it works flawlessly with Xcode 9 and watchOS 4.
In the old days, you always had to install iTunes on your PC to update or sync your iPhone. There were neither over-the-air updates nor iCloud backup or synchronizations. Just as you thought those days were gone, Apple came out with Apple Watch - the tiniest member of the personal devices family. Despite its coolness and elegance, Apple Watch was clumsy. Except for telling time, you needed a paired iPhone to do literally anything. You were always presented with a loading spinner that would sometime go on for seconds, and the navigation was awkward and you had to drill down few pages on a tiny screen to get to your info.
In watchOS 2 we saw a leap forward and Watch apps started running on the Watch itself rather than the phone. In watchOS 3, overall performance of the system was optimized and apps became faster and more responsive. watchOS 4 continues the theme of performance and new and improved features, including a unified runtime process between the Watch and the iPhone, a frontmost app state, Core Bluetooth support for BLE devices, and inline audio recording.
