Still receiving errors from the challenge after assigning result properly

It keeps returning me the same error while I assigned the variable result properly. I

The error from the challenge: You need assign the return value of the 'greeting' function to 'result'.

NOTE: This is not an error from the compiler.

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

    return greeting
}

var result = greeting(person: "Tom")

Hi Timo,

A coupe of points there.

First your returned tuple is in the wrong order - it should be greeting then language.

I like your conversion of the greeting constant; that's cool. I hope the compiler appreciates it too!

My code looks like:

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

    return (greeting, language)
}

let result = greeting("Tom")

Yep, correcting the order and modifying greeting works just fine. This just passed:

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

    return greeting
}
