Swift Functions Stage 2 Challenge 2

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

    return (language, greeting)
}

let result = greeting("Tom")

I keep getting Your 'result' variable has the wrong value. In the Xcode playground everything seems to be ok.

Hey your return was wrong instead of: return (language, greeting) its:

return (greeting, language)

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

    return (greeting, language)
}

let result = greeting("Tom")

I've updated your return types order as it was still the wrong way around.

Thanks, that worked. Since it is a named tuple, does the order matter?

does the order matter?

No it doesn't, when you're using anything that's named you can specify it out of order such as the below example, all you need to do is simply reference the named value and assign it.

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

    return (greeting: greeting, language: language)
}
