Swift Basics - What is an Array? (Challenge)

I need to print the number of items in the array using println. I've tried to do this by assigning todo.count to a variable and then printing that variable with println. This kind of works in Xcode playgrounds but doesn't get me past the challenge.

Can you give me an example of what to do?

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

var arrayItemCount = todo.count

println("\(arrayItemCount)")

You don't need a new variable, all you need is:

println(todo.count)

That's probably the best way to do it. Thanks a lot!

Try to delete arrayItemCount and instead say println("(todo.count)")

Hmmm... I can't make backslash in a comment, but you know what i mean

Hey, yeah I know what you mean. This worked without the backslash too and you could also just write println(todo.count) Thanks for the answer!
