Why does it say "You need to use println", when I am using println?

I have no idea

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

Well well, because your while condition index > numbers.count isn't correct, index begins with 0, and it's not greater than numbers.count, therefore, even though you have your println in while loop body, it never get a chance to run, not even once. That's why you are getting the You need to use println error.

Change it to index < numbers.count
