Exact same thing as Node allowing people specialized in javascript to easily transition to the server.

There is nothing for me in it, there is nothing for you in it, but there is something in it for the swift developers (and thus, for IBM).

I transitioned from Python to Node and from Node onto the whole stack. I think a lot of people did this.

There are presumably still a lot of people that see benefit in being able to write one programming language across their whole stack.

Just like not everyone using node started as a frontend js dev who transitioned to server side, if Swift continues to mature on the server there will be people who use it who didn't start as iOS/Mac devs.
