Hi Yen,

This should do it. This will loop through while counter is less than the amount in the numbers array. It then adds the number to the sum, increments the counter and repeats until counter is greater than the items in the numbers array.

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

// Enter your code below

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

Hope that helps, Dave
