Get details about rocket launches by SpaceX


Built with SwiftUI, I made an app to teach myself a bit more about GraphQL. I had previously only been experimenting with it using Node.js and wanted to give it a try on iOS.

Thankfully the team at Apollo has created a great GraphQL client that made it fun & easy to write fulfilling queries. By using the client I was able to list data about SpaceX launches. The data is fetched from an open API that I found.

Even if the app is very basic, I had great learnings with asking for & displaying data using GraphQL. The advantages with having a defined data shape—that is strongly typed—works really well with Swift. It was also easy to structure my code as I knew explicitly what data I was asking for, and thus I did no over-fetching that could happen easily by using REST.

Consider GraphQL an alternative when building a type-safe bridge from client to server. There are already many clients available, getting you quickly up to speed to test it out.
