Task 2 of 3

I am so lost. Please, I am so close to giving up..

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

    return (language,greeting)
}

var result = (greeting)

Never mind, for some reason it worked after I changed the return values to (greeting,language) instead of (language,greeting). But tuples are hard, I can't really figure it out. I am hoping that it will click eventually.

In order to do this, you simply need to use the greeting function, which takes a String as it's parameter. So, the string "Tom" passed to the greeting function would look like this:

var result = greeting("Tom")
