Don't fully understand Tuple question.

Hey,

I don't fully understand what this question is asking. Could someone please explain it ? Really appreciate any help.

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.

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

    return greeting
}

Thank you

Hi Dale,

First up you need to change the method signature to return the two strings and you also need to name them, making sure to do that in the correct order.

That gives you:

func greeting(person: String) -> (greeting: String, language: String) {
    // leave the rest the same
}

So, this method now takes one string and returns two strings in a tuple. The rest of the challenge will deal with the rest of the method - I hope this gets you on your way!

Steve.
