I guess I have an old version (6th edition) of the book. For the Quiz application, which do I choose? Also, where can I find a description of the difference? Thanks!
I don’t have the book, but it is most unlikely to ask you to select SwiftUI. Just select Storyboard because Storyboards have been around for a while now.
SwiftUI is the new way of laying out the user interface. See SwiftUI Tutorial.
