> The Xcode Playgrounds feature and REPL were a personal passion of mine, to make programming more interactive and approachable. The Xcode and LLDB teams have done a phenomenal job turning crazy ideas into something truly great. Playgrounds were heavily influenced by Bret Victor's ideas, by Light Table and by many other interactive systems.

And that just mentions "Playgrounds", which seems to be some sort of editor application written in Swift. It did not inspire Swift itself.
And also, Swift hardly "changed the whole industry", as far as I know.
