Overview of this book

With the increasing amount of new wearable devices hitting the market, wearables are the next wave of mobile technology. With the release of Apple's WatchKit SDK, a whole new world of exciting development possibilities hasopened up. Apple Watch App Development introduces you to the architecture and limitations of the Apple Watch platform, followed by an in-depth look at how to work with Xcode playgrounds. Here, we'll introduce you to the Swift programming language so you can quickly begin developing apps for the Apple Watch platform with the WatchKit framework and the Xcode Development IDE. We then discuss more advanced topics such as Notifiations, Glances, Closures, Tuples, Protocols, Apple pay, and using Swift playgrounds, with each concept backed up with example code that demonstrates how to properly execute it. We also show you how to package and deploy your Watch application to the Apple AppStore. By the end of this book, you will have a good understanding of how to develop apps for Apple Watch platform using the WatchKit framework and Swift 2.0.

In this chapter, you were introduced to the architecture behind the WatchKit platform, and we discussed how the WatchKit framework is responsible for handling the communication between Apple Watch and the paired iPhone over Bluetooth as well as the differences between the WatchKit app and extension. We then moved on to discussing the WatchKit application life cycle and took an overview of what happens when an app is launched on Apple Watch and the associated classes and methods that are called before taking a look at some of the limitations that the WatchKit framework currently has.

In our next step, you learned about Apple Watch Human Interface Guidelines to ensure that we develop our apps in accordance with Apple's best practices. Finally, we got an insight into some of the great new features and additions that are coming as part of the watchOS 2 platform.

In the next chapter, you will learn how to work with Xcode's Interface Builder and some of the controls that come with the WatchKit...
