iOS Swift Functions and Optionals Parameters and Tuples Tuples

Tuple

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.

Can someone advise on how to do this?

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

    return greeting
}

Watching the video around 4:10 in the video he begins creating a Tuple were he passes more than one value. I'd go back and watch it. The final code ends up being this.

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

    return (greeting, language)
}
