Tuples

This challenge is over the top ambiguous, both in task and response. Been through the tuples videos twice and, since the example in the vids is so different than the challenge, I'm struggling to draw a correlation to what I'm missing. Any help is greatly appreciated.

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

    return greeting (greeting, language)
}

You must return it referred by name as the challenge request: <br/> <br/>

// Make sure to name each item in the tuple greeting and language (in the return part)
// Like this: (greeting: String, language: String)
func greeting(person: String, language: String) -> (greeting: String, language: String) {
    let language = "English"
    let greeting = ("Hello \(person)")

    return (greeting, language) // remove the extra word 'greeting'
}

Don't worry Chris, it's totally normal when you start programming in Swift.

In order to enhance your knowledge I highly recommend you to read this Apple Book called Swift Programming Language 2.1. It will help you to understand the basics along this course.

Hope it helps!

Regards.

Yes, I've got it! Was hoping to postpone becoming absorbed in that until after these tutorials, but I take your advice in the spirit it was offered - there is no one-size-fits all panacea! I'm on it! Thanks again.

Thanks Felix. Part of my confusion stemmed from executing the return as -> (String, String) in my own playground (v7.1.1), without error. I'm still trying to get my head around what the Treehouse Team deems critical to challenge response detail, while reconciling that with what shows up in my own playground when I test the code first. Some of this stuff is dated too (e.g. println()), and some is nonessential, if perhaps standards biased.
