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.

So the actual flow of our user experience is very simple and is linear in nature—the user collects data, stores, and sends it to the iPhone, there are no branches in the user's behavior.


We will need to make use of the following frameworks provided by WatchKit:

  • Core Location

  • Watch Connectivity

We have seen in previous chapters how to leverage Watch Connectivity and we will see shortly the few simple steps we need to take, in order to access core location.

As far as custom structures are concerned, we need to create the following classes:

  • Shared constants, to facilitate data exchange between the watch and the phone

  • A Watch Connectivity manager, as we have created in previous projects

  • A location manager to fetch and store location data and make it available to the interface controllers

  • The main user interface and its associated WKInterfaceController class

  • An interface and its WKInterfaceController, to present the plotted data in table form

  • The table row controller,...
