Unofficial Sandwiches

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. πŸ€·πŸ»β€β™‚οΈ

Still, here is a working unofficial version of the Sandwiches app developed to help you along.

iOS Development Class at Stanford πŸŽ“

It’s looking easier than ever to learn from Stanford University. The Computer Science department has posted their latest class on Developing Apps for iOS online. 🀯.

It’s free. It has lecture videos, handouts, and assignments. As far as I can tell, you get everything but grades and a diploma. πŸ€·πŸ»β€β™‚οΈ. But feel free to make an app!

It currently covers SwiftUI, MVVM and the Swift Type System, Reactive UI Protocols Layout, and Grid enum Optionals.

Communication Patterns in SwiftUI

Are you wondering how to get some information from one component to another in SwiftUI? Too many options to consider? This helpful post walks you through all the scenarios.

  •  From Parent to Direct Child – Use Initializer

Developing features for a large, established app, I often run get slowed down trying to throw together a new screen. You have to find the right spot in the code to update, build the whole app (not just what you changed), log in, and drill down to the right spot to try out your creation. Something’s off? Do it all over again.

Which is why I love the idea of the Playbook library, which is “a library that provides a sandbox for building UI components without having to worry about application-specific dependencies.” Yass! 🀟

Supports both SwiftUI and UIKit.
