Wow, what a chapter. We have seen how to obtain open source data using NSURLSession, including composing URL's and caching the results to reduce data traffic, we have seen how to format the data returned by our requests and parse it to obtain the information we need, and then how to present that information in a table. We have used the console to inspect returned data, added user alerts when errors occur, and pushed WKInterfaceController programmatically, as a more flexible form of navigation. Finally, you have added a Glance Scene to your app.

In the next chapter, we will be using another (similarly advanced) cornerstone of WatchKit development: Core Location. These are mobile devices, after all!
