Loops challenge task

Any ideas, i can't seems to get around this code challenge.

loops.swift 
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0

// Enter your code below
var total = numbers.count

while counter < total {
    print(counter)
    counter += 1
}

sum += numbers[0]

Right now, you are adding the first element of the array to the sum. What you should do is add each element in the array to the sum. The challenge wants you to do that one at a time, one element for each iteration of the loop.

Hop that helps!
