There're a few syntax errors here.

  • Missing the } at the end
  • there shouldn't be : before the variable name index
  • you don't have a list named todo, your list is numbers 
let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
var index = 0

while index < numbers.count {
    println(numbers[index])
    index++
}
