iOS Swift Functions and Optionals Parameters and Tuples Tuples

Struggling to return two values in a tuple. Not sure where my mistake is. I may be completely missing the mark here.

I'm looking to return two values through greeting as an tuple and i'm getting a ton of compiler errors. Any idea how to fix? I've been struggling with Tuples for some reason. Perfectly understand the concept, just the syntax is catching me up.

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

    return greeting
}

Hi Tyler,

1) Hashtags can be used if a function's label and parameter names are the same, so if we were to hashtag anything, it would be before the parameter on the left side of the return arrow.

func greeting(person: String) -> (greeting: String, language: String) {

2) Let's update the return statement to include both greeting and language. Since we can't have two return statements, we'll have one return statement return both values.

    return (greeting, language)

Hope this helps!
