Good afternoon, tell me the order of studying these three books for the best understanding. If my ultimate goal, quality MVVM with combine and swiftUI.
For your goal, I would go through the books in the following order:
The Combine book has some projects where they use SwiftUI so going through the SwiftUI book first would help you with the projects in the Combine book.
Catalyst is a framework to convert iOS apps to the Mac. Learning Catalyst is not going to help you learn SwiftUI and Combine.
I fell you should start with Combine first then SwiftUI, followed by Catalyst
