Function return challenge bug?

My code seems to work perfectly fine in xcode playground but it doesn't work here. I keep getting the error message "Bummer! We try passing the parameter "Fred" through your function, your function only prints out "Fred" instead of "Hello Fred") Is it a bug with treehouse's editor?

returns.swift 
func greeting(person: String) -> String {
     return person
     }

println("Hello   " + greeting("Tom"))

I think it is asking for you to return the statement "Hello (name)". So you would have to Interpolate the incoming variable, much like the following.

return "Hello (person)" of course have the forward slash before person.
