Create Breakthrough Apple Watch Apps with the New watchOS 2 and the Updated WatchKit Framework!

Apple Watch is improving quickly: Using Apple’s new watchOS 2 operating system and the updated WatchKit framework, you can create tomorrow’s hottest wearable apps. Learning WatchKit Programming, Second Edition, will help you master these technologies and gain the same “early mover” advantage that early iPhone developers enjoyed.

Leading iOS development trainer and author Wei-Meng Lee guides you step by step through architecting, designing, and building cutting-edge Apple Watch apps. You’ll learn how to make the most of the newest platform improvements, including direct programmatic access to key hardware features; support for new Watch Connectivity Framework APIs; and new ways to use location, consume web services, and persist data.

Using practical Swift code examples designed for clarity and simplicity, Lee guides you through building apps from the ground up. You’ll learn how to build native watch apps that perform exceptionally well on their own and how to integrate your apps with iPhones to do even more.

Coverage includes

• Writing high-performance, native watch apps that run independently of the iPhone
• Accessing hardware, including Digital Crown, microphone, and Taptic Engine
• Storyboarding apps and testing them on the Apple Watch Simulator
