Hi Kyle, the Code Challenge asks you to: Print out the number of items in the todo array using println.

What your current code does is it prints "0, 1, 2". What you need to do is print the number of items in your array todo by using .count

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