let result = greeting("Tom")

...doesn't seem to be the right answer for the second question of the challenge. This works in Playground, however?

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

    return (language,greeting)

let result = greeting("Tom")

The question is asking for a variable named result. You declared it with let, though.


Having said that, I just tried using let and var and both worked!

My code looks like:

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

    return (greeting, language)

var result = greeting("Tom")

Maybe it is the order of your greeting and language? It does ask for greeting then language!

Yep, it turned out to be the order. let wasn't the issue.

We got there! \o/

var result = greeting(person: "Tom"). Remember to hashtag #Person in the function
