The question mostly arises when you want to build a greenfield cross platform app. I chose SwiftUI, but feel like I might regret not going Catalyst. I think Apple doesn't usually blunder around like Microsoft with these things, but actually pulls through long term strategies. We are in an awkward transition imho. AppKit/UIKit are super mature technologies, SwiftUI is the future but kinda lacking and Catalyst is either a shortcut to speed up Mac/iOS convergence or a backwards attempt to get more advanced iPad apps. It's all fine as long as SwiftUI is actually the future. If any of the others are relevant in 10 years, more than Obj-C is now vs Swift, I'll be disappointed. I don't believe SwiftUI is technically 100% AppKit under the hood, but effectively is, for now.
