need help with "retrieving values from array and adding them to sum"

I can't figure out how to retrieve each value out of array and add it to the value of sum. Need help.

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
}

while counter < numbers.count

Hi Mandaar,

See my below comments:

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

// Enter your code below

while counter < numbers.count {
    var newValue = numbers[counter] //newValue = read numbers at index counter
    sum = sum + newValue 
    counter += 1
}

I hope this helps.
