iOS Swift Functions and Optionals Parameters and Tuples Named Parameters

I am totally stumped..

I cannot get past this challenge.

"Challenge Task 1 of 2 Modify the existing greeting function to have an external parameter named person."

No matter how I modify this code, I keep getting the exact same error message. Can somebody please help me with the correct code here? As well as explaining this in a way someone who has been coding for 2 days can understand it?

Thanks a million!

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

    return (greeting)
}

}
greeting(person: "Jerry")

You only have to put in # before person. You dont have to make a tuple, like you do. :-)

It worked! Thanks so much man. I still have no idea why I don't have to add "->String".. guess I will trust the process :)

You are going to use tuples later, in the challenges. You're welcome :-)
