Hello again,

You need to use the count method on the todo array, since you want to print out the number of items in the array. What the count method does is count how many items are in the array.

Example code:

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

And thanks for thanking me! You're quite welcome!
