iOS Swift 2.0 Collections and Control Flow Control Flow With Loops Working with Loops

While loops code challenge question

I feel horrible for constantly having to ask these questions, but right when I feel I understand what it asks me to do, I end up being wrong! My code below is not working for some reason. I tried a couple other variants on the while loop that also did not work.

I don't want the answer given to me, but I would like a hint. That's one thing I think Treehouse could benefit from adding - little hints for those of us who can't seem to grasp the problems right off the bat.

Thanks, anyone!

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 += numbers[counter]
  counter++
}

I'll try to give hints without giving the answer away.

Hint #1: Think about what numbers.count returns as a value.

Hint #2: Remember that the condition for a while loop must evaluate true for the loop to continue to execute.

Hope that nudges you in the right direction.

while counter < 6 {
    print(counter)
    counter++
}
