you have to add 

index++

to your loop to increment your index or it can crash xcode. I would just make a new playground WITH that line in it and delete the old one.

var todo : [String] = [ "Return calls",
                        "Write post",
                        "Cook dinner",
                        "Pickup Laundry",
                        "Buy hyacinth bulbs" ]

var index = 0

while index < todo.count {
    print(todo[index])
    index++
}
