let result = greeting("Tom")

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

tuples.swift 
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!

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