Building Apple Watch Projects

Overview of this book

With Apple’s eagerly anticipated entry into the wearable arena, the field is wide open for a new era of app development. The Apple Watch is one of the most important technologies of our time. This easy-to-understand book takes beginners on a delightful journey of discovering the features available to the developer, right up to the completion of medium-level projects ready for App Store submission. It provides the fastest way to develop real-world apps for the Apple Watch by teaching you the concepts of Watch UI, visual haptic and audio, message and data exchange between watch and phone, Web communication, and finally Visual, haptic as well as audio feedback for users. By the end of this book, you will have developed at least four fully functioning apps for deployment on watchOS 2.

Setting up the project


In this chapter, we are once again dealing with two apps in parallel, one for watchOS and one for iOS (which has been coded for you, but we will refer to it frequently). All but one of the files (SharedConstants.swift) will be used by one target (that is, one of the apps) or the other, and we must ensure that these targets are correctly selected for each file that we create within the project.

Create the required watchOS classes

We will begin by creating the Swift files that we will need. Once this is done, you will have a good overview of the overall structure of the project and an idea of how the pre-coded iOS files relate to the watchOS app you will be writing.

In the project navigator, select the On Q WatchKit Extension group so that the files we create below will automatically select the WatchKit target in the file creation dialog (where we selected both the On Q and On Q WatchKit Extension targets above) and then perform the following steps:

  1. Create a new Swift file...
