how you use println in the array to find the number of items

everytime I put dot count it would give me error and says you need to use println() but I don't how to

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

Hello Michael, All you need to do is type println() into your code and put todo.count within the parentheses. Your code should look like this...

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

println(todo.count)

Let me know if this helps :)
