[swift-users] the pain of strings

[David Baraff]

I only know a little bit of what I’ve read online in blog posts and such.  I don’t have access to the Swift 4 API documentation, since i’m not running the xcode beta yet.

Is there someplace I can see the actual new API’s for String, in swift 4?  i googled but haven’t found it yet.
