Hi, I have just started learning Swift and app development on Xcode. I saw that the books in "Develop in Swift" series (Swift Explorations, Fundamentals and Data Collection) are still based on UIKit and not SwiftUI even though the book has been updated for Xcode 12. I was wondering if it's worth learning UIKit first as given in the book, or is it better to wait for an updated SwiftUI version book, and skip learning UIKit entirely? I don't mind learning UIKit, but as a beginner, if a framework is almost obsolete, I would rather learn something that is going to be useful going forward. It would also be great if someone from Apple can clarify if there is going to be a SwiftUI version book anytime soon?
