Measure strings using their character count

Available from Swift 2.0

Paul Hudson      @twostraws

In Swift 2.2 the way strings are measured changed yet again. What was countElements() became count() in Swift 1.1, and in Swift 2.0 was removed entirely.

Instead, you should access the characters property of your String, then call count on that, like this:

let string = "Hello, Swift!"
let count = string.characters.count
print(count)

Note: This has changed in later versions of Swift – you should access the count property of strings directly.
