I am assigning the function greeting to the variable result but it still says that I am wrong. Would you please help.

I can't figure out what I am doing wrong and I have been stuck on this coding challenge for a long time. Would you please guid me through some of the steps I am missing. Thanks!

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

    return (greeting,language)

    var result = greeting(person: "Tom")

}

Hi Austin,

You have a couple of problems with your code which are:

  1. You've declared your result variable within the greeting function, it needs to be outside the closing curly brace

  2. You've prefixed the parameter for person with person: which is only required for named parameters, that isn't the case here so it can be omitted.

Aside from those two minor problems your code was pretty much spot on.

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

  return (greeting,language)
}

var result = greeting("Tom")

Happy coding!
