This is the challenge: Using the value of counter as an index value, retrieve each value from the array and add it to the value of sum.

For example: sum = sum + newValue. Or you could use the compound addition operator sum += newValue where newValue is the value retrieved from the array.

You need to use the count property on the numbers array to get the number of items, in this case Int numbers, the array contains. 

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


while counter < numbers.count {
    sum = sum + numbers[counter]
    counter += 1

}
