COMPLETELY lost on Tuples in Swift

This section on Tuples has gone way over my head. I still don't understand how they're used. I guess for now I'm just going to have to skip this code challenge because I have NO idea what it's asking me to do or why I'm doing it.

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

    return greeting
}

A tuple is essentially a group of values that can be treated as a single entity. Tuples are useful for storing related or temporary values in a single container.

In the first part of the challenge where it asks you to modify the greeting function to return 'greeting' and 'language' as a tuple, the updated code would be this:

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

    return (greeting, language)
}
