How do i make my function return greeting and language as a tuple?

I cannot figure out how to make my function return both "greeting" and "Language" as a tuple.

tuples.swift 
func greeting(person: String) -> (String, String) {
    let language = "English"
    let greeting = "Hello \(person)"
var tuple = (language, greeting)
    return tuple
}

func greeting(#person: String) -> (greeting: String, language: String) {
    let language = "Spanish"
    let greeting = "Hello \(person)"

    return (greeting, language)
}

let languageGreeting: (greeting:String, language:String) = greeting(person: "Tomas")

Thanks, Don. I was a bit confused with Tuples, and I really wasn't sure what to do with this one. It's a bit clearer now. Basically, just return the two named return types! Right?
