The comments mainly relate to the Mac OS implementation, which is clearly very early and not fit for production. As he points out the iOS version is more stable. The company I work for are already shipping a SwiftUI iOS app, and plan another one. I've been using SwiftUI for design and prototyping since release on iOS, to the point where it's faster for me to prototype on SwiftUI rather than Figma or Sketch. Particularly with animations and overall experience. The problem for new people is the error reporting is still pretty bad, and it gets flakey if your views are too big. The key is to keep views small and compose them. It's also hard moving to a declarative model for UIKit devs who haven't done React.
