463 PointsSwift collections and control flow: challenge task 2.
I’m not sure what they are asking for with computing the sum. I tried a few of the loops from the challenge but nothing is working and I’m not getting a preview to see what I did wrong
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code below
while counter <= 7 {
print(counter)
counter += 1
}

is ran), you should eventually get a total sum of the numbers in the array.
while counter < numbers.count {
sum += numbers[counter]
counter += 1
}
