I know a handful of dev shops that will begin using swift for all new client projects. I doubt we'll see swift being intermingled into legacy projects, although I'm pretty sure we'll see tons of objc intermingled into "swift first" projects. iOS apps are so lightweight in general that kicking off new projects in swift wont be much of a risk.
