What is wrong?

let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] var index = 0 while index < numbers { println(numbers[index]) index++ } It's telling be that I'm wrong but it never gave me a variable to do a loop with so I created the variable index.

you need to compare the index to numbers.count in your condition, not numbers

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