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

Hello :

Try calling your function with the parameter name.

func greeting(#person: String) -> (greeting: String, language: String) {
    let language = "English"
    let greeting = "Hello \(person)"
    return (greeting, language)
}
var result = (greeting, language)

greeting(person: "Tom") // Call your function like this

its still saying that I need to "assign the return value of the 'greeting' function to 'result'.'

If the challenge is asking to add the result to a variable, you should then call it like this

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

    return (greeting,language)
}

var result =  greeting(person:"Tom")
