this code works fine in swift while counter < numbers.count { sum = sum + numbers[counter] ++counter }

Question

so why won't it let me continue

while.swift

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

// Enter your code below
while counter < numbers.count {
    sum = sum + numbers[counter]
    ++counter
    }

hmm, I'm surprised it's working for you in your playground. The short hand operator "++" was deprecated in swift 3. Try counter += 1 or counter = counter + 1

yeah for the swift 3 I used the counter += 1 but the track I am doing is swift 2.0 (because thats what devmountain says I have to do)

hmm ok. Well it passed for me this way:

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++
}
