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.
