This challenge is asking you to return a tuple from the function given. The first step is stop modify the return type so that it can return a tuple. Your function should look like this:

func greeting(person: String) -> (greeting: String, language: String)

With this function signature, your method will return a tuple that holds two string. To complete the method, you need to modify the return statement, and your function should look like this:

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

    return (language, greeting)
}

The method will now return the language and greeting Strings stored inside a tuple.
