Please, I do not understand tuples at all. I am currently working with challenge 1 of 3, any help?

Can somebody help me with this task? Or understanding tuples for that matter. It is so frustrating that I can not figure it out!

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

    return greeting
}

Chris's answer is absolutely right... in addition, Swift 2.0 has removed "#".

A tuple is nothing more than a data type that holds multiple values. In the case below we return a tuple that holds two values.

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

    return (language,greeting)
}

Thank you for helping me out Chris! Now, how do I create a variable "result" and assign it to the tuple that returns from the function "greeting"?
