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.
