My friends I am having trouble completing this one. More than likely I don't quite get what is actually asking me.

Ok I think I know what is asking me but I feel I am not doing what is asking me. On Xcode 7 works as I belief as intended but I don't know.

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

    return (language, greeting)
}
var result = greeting("Tom")

When you call the greeting function you are using only 1 variable. The challenge wants a tuple. You have 2 variables in the function, but you dont pass 2 values when you call function.

Weird deal, everything looks pretty good above, I got the challenge to both pass AND fail with the code below. Looks like you've correctly defined the expected return value correctly and returned the correct values in the function. Refresh and try again :)

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

    return (greeting, language)
}

var result = greeting("Tom")
