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.

The Interface Controllers

With the PBLocationManager in place, we have done the heavy lifting of the app. The interface controllers are very slim in design and simple in implementation.

Create the InterfaceController class

Select the InterfaceController.swift file that was created as part of the Xcode template and replace all of the code in it (including the import statement) with the following:

Import WatchKit

class InterfaceController: WKInterfaceController, PBLocationManagerDelegate {

    var locationManager: PBLocationManager! //1

    override func awakeWithContext(context: AnyObject?) {
        locationManager = PBLocationManager(delegate: self) //2
        locationManager.requestLocation() //3

    func handleNewLocation(newLocation: CLLocation) { //3

    func handleLocationFailure(error: NSError) { //4


What we are doing here is writing the bare minimum code necessary to test...
