Not in favour, sorry. While I've used this kind of pattern in Javascript I just don't see what it really adds compared to a more explicit name. As a general rule I prefer everything to be explicitly named except where a case is genuinely trivial (like the dollar syntax for closure arguments).

If it had more benefits maybe, but I just don't see them.

No, I think that allowing the dollar sign could be confusing alongside dollar sign variables in closures, and I feel that Swift is better being explicit where possible.

It's similar to a lot of Javascript libraries that use the dollar sign for values, but I've never felt that I was really gaining anything significant by using it as a variable name.

Quick read.
