Println + Count method

The challenge asks that I print out the number of arrays using the println but when I tried it it just won't work. It says that I need to summon the "count" method, which I think I did? Don't know what I'm missing. Thanks.

arrays.swift 
var todo: [String] = ["Learn Swift","Build App","Deploy App"]


println: todo.count

You wrote println wrong. Below is correct answer :)

var todo: [String] = ["Learn Swift","Build App","Deploy App"]

println(todo.count)
