Tuples

I don't get how i should do this. This is my 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. This is my error: Bummer! Your function needs to return a tuple with elements named 'greeting' and 'language'. Can someone help me please?

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

    return greeting
}

let (greeting) = greeting(person: \(person), language: \(language))

Your code should look more like this:

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

    return (greeting, language)
}

It sais : You need to define a function named 'greeting' that takes one String parameter.

Weird, it sais: Bummer! Your code could not be compiled. Please click on "Preview" to view the compiler errors. But when i check the compile errors nothing shows up.
