I love the idea and name of this project.
Apple demonstrated how to build an app with SwiftUI by doing a detailed walk-through a Sandwiches app.
But they didn’t give you the code! I guess that’s because they want you to write it yourself. 🤷🏻♂️
Still, here is a working unofficial version of the Sandwiches app developed to help you along.
