I don’t know about you, but I think this pretty incredible. We have a 100% pure Swift code base that is powering a web app. And even better, we are using the same model that we used over in UIKit and SwiftUI. This is showing a possible vision for cross-platform development in Swift. One model powering features on two vastly different platforms: iOS and the web. And it’s all thanks to the cross-platform observe function that comes with our Swift Navigation library, as well as Swift’s amazing Observation framework.

But we are still missing some of the most important behavior in the feature, which is the network request that loads a fact from the server and presents it to the user. This is going to be a little more difficult than everything we have accomplished so far because it involves new APIs for making network requests and it involves asynchronous work.

Let’s dig in.
