What's wrong with this code?

I am getting an error message stating that I am not returning the greeting and language elements.

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

    return (greeting, language)
}

Hi Girri,

You're close! At the top though, you'll want to change the return type so that a tuple is returned, rather than string.

Example:

func greeting(person: String) -> (greeting: String, language: String) {

Hope this helps!
