Not sure how to change this function so it returns multiple values...

[Problem]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.

I don't see how to get it to return this is the first assignment i've gotten stuck on. I under stand that you can have multiple return types but I don't get how to solve this one.

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

    return greeting
}
