sorted function in Swift 2

Question

I\'m sorting an Array like this:

var users = [\"John\", \"Matt\", \"Mary\", \"Dani\", \"Steve\"]

func back (s1:String, s2:String) -> Bool
{
    return s1         


        

Answer 1

Another way to use closure is:

var numbers = [2,4,34,6,33,1,67,20]


var numbersSorted = numbers.sort( { (first, second ) -> Bool in

    return first < second
})
