iOS Swift Basics (retired) Control Flow While and Do-While Loop

My code wont run...

I have tried to solve this code challenge, but when i go to input my answer it wont check it. Could someone tell me if my code is right or not so i can move on.

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])}

Your code appears to not be running because it runs forever, and the checking server hangs up. The reason it runs forever is because you never increment the index variable. A working version would look like this:

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])
    //You need to add 1 to index every time the loop runs, so it doesn't run forever
    index++
}

How does index increment?

Thanks a ton mike
