In Swift 1.0 you would count an array like this:
let items = [1, 2, 3]
println(countElements(items))
The countElements()
function has been renamed to count()
in Swift 1.1, so the new code is this:
let items = [1, 2, 3]
println(count(items))
Note: This has changed in later versions of Swift – count
is now a property of strings and collections.
