I have already assigned the return value of the 'greeting' function to 'result', but it is not working!

It doesn't show any errors, and the code works on Xcode. Please help!

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

Hello Nelson: You were close, you just forgot to do the return as a tuple, and to place the var outside of the function. This is what it looks like.

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

    return (greeting, language) // This the tuple return
}

var result = greeting("Tom")  // this variable goes outside the function
