I do want to give a shout-out to this tool[0]. The "official" SwifUI docs leave something to be desired, so a developer wrote an awesome doc tool. I found out about this tool from an instructor at a class I took.
The official SwiftUI tutorials are absolutely amazing though. But I agree about SwiftUI-labs and the app, they are fantastic resources if you want to go deeper.
