2,930 Pointsit's really strange. I keep getting the error. even though it's identical to previous answer.
// Enter your code below while (counter < numbers.count) { sum += numbers[counter] counter++ }
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++
}

7,018 PointsAs you haven't specified the error you're receiving, I can only guess at the problem.
However, I notice that you're using the ++ operator. This was deprecated in Swift 3 (meaning it is no longer used) - the way to increment a value by 1 now is to use += 1 instead.
while (counter < numbers.count) { sum += numbers[counter] counter += 1 }
