In Swift 2.2 the way strings are measured changed yet again. What was
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.
