Hi Matt,

A while loop will run forever unless we explicitly give it a condition that stops it from looping, we can do this by setting another variable which in the example below I've called count but you can call it anything you want. Each time the loop executes we retrieve one of the values from the numbers array and increment the count variable by one.

Once the count variable reaches 10 the condition will be met and the while loop will stop executing.

let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
var count = 0

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

Happy coding!

Ahh thats right forgot about having to end it manually with the count variable. Thanks for the speedy answer :)
