Well, we finally have data working on our app. We are not using a service, but if we wanted to, it wouldn't be hard to add it. Working with local JSON files is pretty close to working with an API feed. You should feel confident doing either. One thing I love to do is this: when I know what the feed is like, but I do not want to write that portion yet, I will create static JSON files of the feed and work with those. Using static JSON files allows me to focus on getting the app to where it needs to be, and not get stopped because of the API data layer.
In this chapter, we learned what JSON is and how to use that JSON feed to make data for our app. We also looked at how to pass data using segues.
In the next chapter, we will look at how to display even more data.
