I don't understand what I am doing wrong

It tells me I haven't assigned the variable result to greeting("Tom"), but I have

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

    return (greeting,language)]

var result = greeting("Tom")

Two things that I see-- First, you are never closing the function with a }, I think there is an unintentional ] instead.

Second, adding the # makes a named parameter, meaning to call the function you need to use the argument's name within the parenthesis.

var result = greeting(person: "Tom")
