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]
sum = sum + newValue
counter += 1
}

4,207 PointsHej Thanks for the help, I was stuck at the same problem, because it was not dealt with in the videos how we can extract something out of an array inside a while loop. It was very confusing. Also I do not understand how this works because xcode doesnt compute this while loop for me and shows me no sum values.
