First, thank you to matteomanferdini.com for sponsoring appcoda.com this week. Matteo is now offering a free guide to teach you how to architect SwiftUI apps using MVC and MVVM. You can check it out here.

Regarding the SwiftUI companion guide, we’ve almost migrated the demo app from UIKit to SwiftUI. Later this month, if you’ve purchased the professional package of our Swift/SwiftUI book, you will receive the guide and the complete project for free. Please stay tuned and sorry for the delay.

As always, hope you enjoy the collection of programming tutorials.

Talk soon,

Simon
