> Apple also isn't dogfooding much with Swift.

That's because it didn't have a stable ABI until Swift 5, released last year. Now that it does, a lot of their iOS/iPadOS apps have been rewritten, at least partially but sometimes fully, in Swift; this includes some of their Catalyst apps on Mojave and Catalina.

The only app I know for sure to be fully written in Swift, thus far, is the Apple Developer app (previously called WWDC), but I know there are others (they were mentioned in last year's WWDC sessions).

> Swift UI has been in development for 4 years

I must have missed this. Where did you hear this? I'd love to see more info about that.

The lack of a stable ABI had nothing to do with preventing Apple from shipping apps written in it.

Chris Lattner said in one of the pod cast, I think it was Accidental Tech, where Swift UI started before he left Apple. Since that was 3.5 years ago, Swift must have been close to 4 years of work.

Well, that may be, but we don't know when a concerted effort began. Just a guess, but this was probably a small team (or individual) trying some things out as an R&D project to see if it had legs. At some point there was enough promise so that the company put serious effort into it. That might have been 2 or 3 years ago. At any rate, it has company focus now.
