That is exactly their plan. Swift could always link into C applications, and they have recently come out with C++ interoperability [1] so things like WebKit etc. can start having parts re-written or new parts written from the start in Swift so they can gradually replace C and C++ codebases instead of trying to rewrite everything (which sucks because even for things much, much less complex than WebKit, you can have a team working for three years working on a replacement and it’ll have less features than the original had when you started).

They’re even working on an embedded subset for embedded devices so things like microcontrollers like battery management, the Secure Enclave etc. can run it.
