iOS Swift Functions and Optionals Parameters and Tuples Tuples

I seem to be stuck with the assignment of the func to the result var.

I've tried everything as explained in the videos but it doesn't seem to work...

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

    return (language, greeting)

let result = greetings(language: "Tom", greeting: "Hello \(person)")

Ok Charlie, let's go step by step.

First of all you don't need #language as a parameter here

//this is wrong
func greetings (#person: String, #language: String)

//this is right
func greetings (person: String)

Now let's see what task in next step says: "Create a variable named result and assign it the tuple returned from function greeting. (Note: pass the string "Tom" to the greeting function.)"

so what you need to write is this code

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

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

If you need help with the third task just say. But always try to find solution by yourself first :)

Thanks ! But that's actually what I wrote after I asked my question (and kept thinking about it :-)), but the "check work" button kept telling me there was a mistake... so strange =/

Thanks anyways for your help !
