Help on this Array challenge?

"Print out the number of items in the todo array using println. Part 2 challenge"

Says I have to "Call" the count. When I get the answer wrong.

So, I attempted to write println(todo.count) within the box brackets because the challenge say "in the todo (array) using println." I wrote the println() function in the beginning of the box brackets with a comma at the end.

I am completely stuck as I don't understand where else to type the function.

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

You don't need to use box brackets with a println, just curly ones.

The correct answer is simply: println (todo.count)

So apparently I was right and so were all of you except we all forgot one symbol. The semi-colon.

It was supposed to be this.

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

I don't even remember the video showing use of that symbol. I will go back and check the video again.

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

I've tried all the above answers. I get this in response.

You need to call the 'count' method on the array.
