iOS Swift Functions and Optionals Parameters and Tuples Tuples

I'm not sure how to make it to tuple?

Is language a boolean value? Did I over think this question?

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

    return greeting
}

Hi xiaohu li, this was answered brilliantly by Chris Upjohn over at: https://teamtreehouse.com/forum/not-sure-on-the-tuple-question-ios-swift-to-modify-the-greeting-to-return-both-language-and-greeting

To answer it here for you, you slightly over thought it in respect to you are still in the mind set of the video before the question, there is no bool value in this question. Language is a String = "English". To return these values you must change the return statement along with the return type:

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

    return (greeting, language)
}

AS you can see return is now a tuple of greeting and language, and the return type is now greeting as type string and language also of type string.

Hope this helped

Dom

Thank you for your help! I missed the first line: language: String part.
