Swift 3 Collections and Control Flow challenge task 2 of 2

I'm completely stuck on what the question is asking.

loops.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 += 1 
}

The challenge task is asking you to do the sum compute now. sum is going to sum all the values in the array numbers = [2,8,1,16,4,3,9] and you already have an index to read the array values from the beginning to the very end. numbers[index] should get the value of the index position number in the array.

Good luck with that and keep up the hard work!
