task 2 of the challenge states: Print out the number of items in the todo array using println.

the Swift eBook states:

To find out the number of items in an array, check its read-only count property

and provides the following example:

println("The shopping list contains \(shoppingList.count) items.")

so all you need to do is print the count property of the todo array

var todo : [String] = ["Learn Swift", "Build App", "Deploy App"]
println(todo.count)
