Create a variable named result and assign it the tuple returned from function greeting.

I can't figure out how to assign the tuple to the variable, result.

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

    return (greeting,language)
}
var result = greeting(person: "Tom",language: "English")

Hey Jeremy Siegel,

You're close! Just a few things to fix here with your calling of the greeting function. First, you don't pass in language as an argument because your greeting function only takes one argument, person, of type String. Second, you don't need to use the name of the first argument because Swift omits this by default when you call your function. If we change these two things, your code should look like this:

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

    return (greeting, language)
}

var result = greeting("Tom")

Good Luck!
