SwiftUI or Storyboard, what to learn first?

Hey guys new to Swift here. I’ll be having to learn the language and edit an existing project over the next couple months. The project was made in SwiftUI and i read it wasn’t compatible with all ios versions yet. Will I have to translate that to Storyboards to make it compatible for more devices or is this something I don’t have to really worry about and should just go ahead learning SwiftUI?

You will need storyboards if you need to support any version of iOS below 13. If you don’t need to worry about that, then you are safe to only use SwiftUI. Although, fair warning, since it’s still fairly new, there is stuff missing from SwiftUi that you may end up needing storyboards for anyway, such as collection views.
