Still need help

This question is specifically for Michael Lazarz but if anyone could help that would be great, Michael this is the exact code you gave me and it is still coming up with an error, Am I doing something wrong?

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

Hello :

Try this :

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

    return (greeting, language) // this is more clean than (greeting: greeting, language: language)
}

//var needs to be outside (this is for the second part of the challenge)
var result = greeting("Tom")

println (result.language)  // this is for the last part of the challenge

as you can tell you had your variable return inside the function, it needs to be outside of it. Also, the return just needs to call the greeting and language.

Jhoan is close, but he's got a couple extra lines of code. In a later challenge you'll need result.language, but never result.greeting.

All that was wrong with your original code is you set your variable inside your function definition.

Here's all the code you need:

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

var result=greeting("Tom")
