How to convert NSSet to [String] array?

Question

I have an NSSet of Strings, and I want to convert it into [String]. How do I do that?

Answer 1

I would use map:

let nss = NSSet(array: ["a", "b", "a", "c"])

let arr = nss.map({ String($0) })  // Swift 2

let arr = map(nss, { "\($0)" })  // Swift 1
