[swift-evolution] [Draft] Swift implementation Regex added

[Garth Snyder]

> Brent Royal-Gordon: Something to keep in mind when you write your proposal: At least one member of the core team has expressed a desire for regular expressions to be deeply integrated into the language, with strong connections to `case` syntax and destructuring, and a Perl 6-style rethink of the syntax. 

I’d love to see this as well. I’m glad it has some support on the inside!
