Been picking away at this for a while... I can't figure out why it's wrong.

I've tried this so many ways and nothing seems to work! What do I have wrong here?

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

    return greeting
}

The function signature should just be

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

This is what you had but without the extra "greeting" in the parameters. You just need

person: String

After you fix that, the editor will complain about you returning greeting. That is because on that exercise you need to declare a tuple, assign what you want the function to return to that and then return the tuple. Rematch the video this assignment came from if you're stuck and code in the playground along with him while you watch it. Then you should be able to complete this exercise.
