Can't figure out what's wrong while says "Your 'result' has the wrong value in it" let result = greeting(person:"Tom")

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

    return greeting
}
let result = greeting(person:"Tom")

Hi yi yuan,

You have a few errors in your code which are as follows.

  1. You have your person parameter set as a named parameter, it doesn't need to be
  2. You've modified the greeting constant which wasn't asked as part of task 1
  3. You're only returning the value for the constant greeting instead of a tuple containing both greeting and language
  4. As stated in my first point person doesn't need to be a named parameter therefore you don't need to declare person: in front of Tom

The code that task 2 is expecting is the following.

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

    return (greeting, language)
}

let result = greeting("Tom")

Happy coding!
