I'm stuck on this challenge

I know the concept of the while loop, but I don't know how to retrieve the values in the array

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
var newValue = numbers[]
sum += number
}

var newValue = numbers[counter]

Index - that's how you access an item in array. For example, if our array was [1,2,3] and counter had a value 0, numbers[counter] would actually mean numbers[0] and that means "I want an item which is in this array on position 0" which in this case returns 1 :)
