Woah, you're super closed, all you need is parenthesis around language, greeting to make it tuple.

return (language, greeting)

What do you need to achieve? Try this:

func greeting(person: String) -> String {
    let language = "English"
    let greeting = "Language: " + language + ".\n Hello, " + person + "!"

    return greeting
}

println(greeting("Sander"))

nay, the question is asking to return a tuple, not a string.
