maybe I don't understand the question I'm being asked

I've given this problem all I got the passed few days. I really could use some help so I can move forward.

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

    return greeting
}

Some languages can't return more than one thing at a time. However, Swift can. What it's asking here is for you to return both the String greeting and the String language. Your code is currently just returning greeting. Take a look at my solution:

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

    return (greeting, language)
}

Before we return multiple items, though, we have to first tell the function that that's what we're going to do. This is why we have the (greeting: String, language:String) in the first line. It tells Swift that we're planning on returning two values of the String type with these names. Happy coding! :smiley:
