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

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++
}
