lost with this loop stuff. asking to print out array using loop. let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] var index = 0 while index < numbers.count true { println(numbers[index]) index++ }

while_loops.swift 
let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
var index = 0
while index < numbers.count true {
  println(numbers[index])
  index++
  }

This is very close, you just don't need the true in the while statement because it already requires a boolean expression and will continue to loop as long as its true. It would be repetitive to say true again. One way of stating what you wrote might be "while it is true that index is less than the count of array numbers is true, do {}" instead of just "while it is true that index is less than the count of array numbers, do {}".

hope that helps!
