Completely lost on this "while" task

"Given an array of numbers, print out each number in the array using a while loop and the println statement."

This is what I have so far, I know its far from being correct but I dont know what to put. I've watched the video several times and I've even tried copying him step by step.

Please help me understand!

while_loops.swift 
let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

while numbers {
  println(numbers) 
    index++
    }

Nvm, got it!

let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

var index = 0

while index < numbers.count { println(numbers[index]) 
index++ 

}
