Wrap-Up

You now have an iPhone app with a WatchKit extension to play around with in the iOS Simulator and on Apple Watch if you have one. You also have a better understanding of how WatchKit extensions and WatchKit apps go hand in hand to extend your iPhone apps. Go ahead and play around a little with the objects in the Object Library in your storyboard. Look at the options available to customize the interface objects in Xcode’s Attributes Inspector. In the next chapter we’ll take an in-depth look at the various interface objects in WatchKit and get one step closer to writing our killer app.
