Hey Marco,

the problem with your code is that you're passing the greeting function two arguments even though it just has one parameter (person). The function returns a tuple with two values but it just takes this one parameter. If you remove the second argument it should look like this and work:

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

    return (greeting, language)
}

var result = greeting("Tom")

I hope that helps! :)
