Hi there, was wondering if i could have some help with some while loops, thank you

I'm really struggling with these loops, has anyone got a guide of some sort of contact i can ask them a few things about, thank you for your help!

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

// Enter your code below

while sum < counter {
  numbers // do i add numbers from the Number array up ? CONFUSED ! :( 
  counter++
} 

// THANKS!

I believe you need to change your while statement to something like while counter < 6 /* can also do: while counter < length(numbers) { sum = sum +numbers[counter]; }

Im not in this class so you will need to verify the length function name: it may be len(). I think the point of the exercise is to add all the numbers up and keeping adding until there are no more numbers. At that point the loop needs to quit.
