Does SwiftUI replace AppKit?

If you want to create iOS applications for the iOS and Mac, then Swift is the best option . Better than Objective-C, and certainly better than the cross-platform solutions. Swift is also a great language for doing games and game logic.

So, yes: SwiftUI is incredibly fast , and all without us having to do any extra work.

SwiftUI won’t replace UIKit until those students @Stadford get into the management of software companies , so it will be a few more years yet.

SwiftUI takes everything Apple learned from UIKit, and provides developers with much better features that are unavailable in UIKit . One of these features includes creating even more powerful applications while at the same time using less code than UIKit.
