I'm asking it to return two strings...but I don't think I'm doing this right at all. I'm lost.

Not sure exactly what else I have to do?

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

    return greeting
}

Hi Andrew,

You're almost there, you just need to return a tuple based on the return type you set for the greeting function like below.

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

  return (greeting, language)
}

Happy coding!

Ah, great thanks!

I think the exercise is a lot simpler than the lesson before it. For some reason I tried all types of other stuff that was totally unnecessary.
