More advanced topics are also covered throughout the book, including communication and data sharing between a WatchKit app and the parent iOS app, working with custom fonts and the design and implementation of custom notifications.
As with all the books in the “Development Essentials” series, WatchKit App Development Essentials takes a modular approach to the subject of WatchKit app development for the Apple Watch, with each chapter covering a self-contained topic area consisting of detailed explanations, examples and step-by-step tutorials. This makes the book both an easy to follow learning aid and an excellent reference resource.
