Create Breakthrough Apple Watch Apps with the WatchKit Framework

With its Apple Watch and WatchKit framework, Apple is challenging developers to build exciting and innovative apps for Apple Watch. iOS developers who master Apple Watch programming now will have the same huge “early mover” advantage that early iPhone developers enjoyed. Learning WatchKit Programming is a complete, hands-on tutorial for all iOS developers who are ready to design and build tomorrow’s hottest new wearable apps.

Leading iOS development trainer and author Wei-Meng Lee covers all of the fundamentals of Apple Watch development and the WatchKit API, from application architecture and design to navigation, notification, and glances. Using practical Swift code examples designed for clarity and simplicity, Lee guides you through building apps from the ground up and shows you how to integrate those apps with the iPhone for expanded capabilities.

The perfect companion to other mobile development books in the Learning Series, this guide helps you extend your iOS skills to a whole new environment, build apps that solve a new set of problems, and reach millions of people in the new Apple Watch marketplace
