Building Apple Watch Projects

By: Stuart Grimshaw

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.

Which is kind of a shame given that the phone offers us some benefits that most apps are likely to be able to make use of. These include:

  • Much greater storage capacity for resources

  • Much greater processing power (and the battery life to do it)

  • A much larger screen

While we will have little use in C-Quence for the first two of these, we will make use of the ease with which our users can give us information using the larger screen, information that we will only collect once, or at least not often.

As mentioned in Chapter 1, Exploring The New Platform, the Apple Watch is at one and the same time an independent device, and an extension of the iPhone, but we can also turn this relationship around and use the iPhone to augment the capabilities of the Watch.
