I gave up my email address in exchange for some free SwiftUI books... you might try them. I liked the simplified App patterns comparing MVC vs MVVM vs SwiftUI.

One of the booklets was The 5 Most Common Misconceptions About SwiftUI (by Matteo Manferdini)- I don't think the misconceptions are that common - but let me know if I'm wrong. The appendix is a nugget titled The New Swift Features that make SwiftUI Possible.

Also on Matteo's site is his Architecting SwiftUI Apps with MVC and MVVM book.
