I still can't get this code challenge right!

In the while loop i have been experimenting with loads of different solutions but success still eludes me!

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

// Enter your code below
while counter < numbers.count { counter++ sum = sum + numbers }

Hi Benjamin,

This is a tricky challenge, especially when learning.

Below is the solution,

while counter < numbers.count {

    sum += numbers[counter]
    counter++

}

However, I'll put you in the direction of this post for a good explanation of it as its much better than one I could offer.
