Summary

You now have an app that fully functions on all devices. You can see how using the Collection View gives your app some variety on different devices with very little code. As you get more and more comfortable, you will find other ways to make your app look unique on different devices.

We could submit the app as it is right now and it would be perfectly fine, but why not take advantage of some of the features that you can implement. In the next chapter, we will do just that by creating an iMessages app for our app.
