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...

tuples.swift 
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)")

result.language
result.greeting

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 !
