Absolutely! I think Catalyst and SwiftUI tell a story. AppKit (on the Mac) and UIKit (on iOS and NOW the Mac) are both probably depreciated in the long term to be replaced with SwiftUI. The whole paradigm with SwiftUI is write the foundational pieces in one place and then tweak for your different platform. I think it's the best approach to getting the best possible apps everywhere!
