iOS Swift Functions and Optionals Parameters and Tuples Tuples

What should I do in task 2 of 3 Tuples Swift?

It is said here that I have to create a variable named result and assign it the tuple returned from function greeting. (Note: pass the string "Tom" to the greeting function.)

Here is my code:

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

    return (language, greeting)
}

var result = greeting("Tom")

And it doesn't work. I don't know why.

Try this:

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

    return (greeting, language)
}

var result = greeting("Tom")

Notice the first line

"language: String, greeting: String" vs "greeting: String, language: String"

Actually, I think there's something wrong there because it said I had an error in:

func greeting(person: String) -> (greeting:String, language:String) { return ("Hello (person)", "language") } var result = greeting("Tom")

BUT NOT IN:

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

WHERE "English" and "language" are both strings so...

Here is the code:

func greeting(person person: String) -> (language: String, greeting: String) {

let language = "English"
let greeting = "Hello \(person)"

return (greeting,language) } var result1 = greeting(person: "Tom")
