Valid solution not working

Why is this valid in Xcode, but not valid as a solution on this page?

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

Try println without using string interpolation on todo.count (You don't need to use quotes, or the parenthesis and backslash)

println(todo.count)

Are those on the same line in your solution? Try moving the println function to a second line or add a ; between them.

They are on separate lines :-(

I'm thinking the page has a particular answer that it wants me to use that I'm just not using. Is there a different string interpolation technique or style I should be using to get it to accept the answer?
