Tuple, single value

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.

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

    return greeting
}
