iOS Swift Functions and Optionals Parameters and Tuples Tuples

Having trouble with the Swift Functions & Optionals challenge

Challenge: Currently our greeting function only returns a single value. Modify it to return both the greeting and the language as a tuple. Make sure to name each item in the tuple: greeting and language. We will print them out in the next task.

Question: I'm confused because this appears to be asking for a function named greeting that also has an argument named greeting. How do I distinguish between the function "greeting" and the argument "greeting"?

Hi Paula, this is the solution of that task. Cheers

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

    return (greeting, language)
}

func greeting(person: String) -> String { return ("Hello (person)") }

// This worked for me.

Note that my post was automatically formatted to eliminate the enter and tabbing that I used for readability. Maybe something Treehouse should look at.
