not sure what I am doing wrong

I am following the video tutorial but I do not realize my error.

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

    return 
}

Hi James,

You're almost there, you have setup your return type correctly as a tuple but you're not returning anything from the greeting function. Rather than re-explaining what tuples are and how to use them see the link below which is a post I made a long time ago explaining them.

The other issue is you have changed the parameter person to be named which isn't required, simply remove the pound/hash symbol so your function signature is instead the following.

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

Hope that helps.
