I also believe there are a ton of free resources for your friend. Excellent ones. For example, RayWenderlich, or HackingWithSwift by Paul Hudson, he has there 100 Days of Swift (That uses UIKit), or 100 Days of SwiftUI. Also...There's the free 14 day challenge by Chris (From CodeWithChris). That is absolutely doable. Now I also offer a 1:1 Coaching Program, but it only involves SwiftUI (So if she/he wants to learn with UIKIt is not the best choice), and it's only a month long, because it's a beta program still. But definitely check the free resources. There's also Build That App! (Or something alike) channel from YouTube.
