Arrays lesson does not appear to accept correct answer

This seems to provide the correct answer in XCode, but I am being told it is wrong.

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

println("\(todo.count)")

I think this answer should help:

The Treehouse compiler doesn't want this message. The reason is, using interpolation here isn't really needed. When you're printing the value of a variable by itself using println, there's no need to interpolate since the value is a number, not being explicitly included within a string. The code you're using would work in XCode however, if you include a backslash

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