Works in xcode but does not let me pass the challenge

I wrote println("(todo.count)") and it showed no errors in xcode. However when i wrote the same thing in the challenge it rejected it, i checked in xcode if it outputted, i opened the console and in both the output pane and the console it said 5. With the only exception that in the output pane it had "" around the 5

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

Wouldn't this give you a 3 instead of 5 because there's only 3 items in the array? Check the directions of the challenge to see if it had any more steps for you to follow.

In the xcode playground i had 5 strings in the array. So that's why, and this was the only objective they gave me: Print out the number of items in the todo array using println.
