Not getting this challenge. How the function name "Greeting" can be the same as the constant name "Greeting"?

I can't solve this challenge. I must be leaving something out. Please help.

There're couple things you need to do here

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

    return greeting
}

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.

now By looking at the code template, the first thing you need to do is change its return value to a tuple

    return (greeting, language)

Next up, since you change the return value to a tuple, you must also change the function's return type accordingly.

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

That's all for this part of the challenge.
