Stuck again on the tuple challenges. The challenge is this...

Using the println statement, print out the value of the language element from the result tuple.

And the attached is what i have. Finding tuples very confusing!

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

    return (greeting, language)
}

var result = greeting("Tom")
println (result, language)

Hey Becky, you were almost there. The challenge asks you to print the language property of the result variable. You can do this using the . operator as result.language

I have also attached the code:

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

    return (greeting, language)
}

var result = greeting("Tom")
println(result.language)

hope this helps :)
