How do I modify my code to return as a tuple

I cannot figure out exactly how to modify this code to return as a tuple.

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

    return greeting
    return language

Hi Dylan,

You're going to use the function definition as your guide. That being said, it looks like there may be a problem with your function signature! I think language is supposed to be of type String. Here's how I would write it:

//I removed the # symbol and changed the return type. Language will be a string, not a bool.
func greeting(person: String) -> (language: String, greeting: String) {
    let language = "English"
    let greeting = "Hello \(person)"

    // Returning a tuple is easy... you just write a tuple!
    return (language, greeting)
