Hi Francesco,

Your current code has the return type backwards, greeting needs to comes first and language second, simply switch them around and the challenge will pass.

Also you don't need to assign the tuple to a variable, you can simply assign it as the return expression.

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

  return (greeting, language)
}

let result = greeting("Tom")

Happy coding!
