Now that we have the foundation of our UI set up in AppsSearchController, we're ready to integrate some JSON data by making some API calls to the iTunes Search API. I'll first go through how the data set can be fetched and interpreted through the browser. Once we have a good understanding of what can be returned, I'll walk through step by step on how to fetch this data in our project. One of the best things was introduced in Swift 3 is the Decodable protocol and allows JSON data to be very quickly parsed into Swift model objects. I'll show you how to set this up in this lesson and how to populate our cells in the next video.
