Just curious why this code would fail?
If I pull into a playground I am able to get the sum perfectly
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[index]
counter += 1
}

sum += numbers[index]
You refer to a variable called index
which does not exist. I'm assuming you meant to type counter
instead. If you fix that typo then your code will work fine.
