Needs some help with the Tuples challenge :)

Hello,

Can you please help me with an explanation related to what I am doing wrong here:

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

    return (language, greeting)
}

var result = greeting("Tom")

I keep getting the error: Bummer! Your result variable has the wrong value in it. Check the task instructions again. even though the request is

"Create a variable named result and assign it the tuple returned from function greeting. (Note: pass the string "Tom" to the greeting function.)"

You have to switch language and greeting i think because it asks for greeting and language in that order

return (greeting, language)

The sentence should print Hello Tom English but if you put the parameters the other way around it will be english hello tom it depends on how you want to string to print but the code challenge has strict conditions

The only thing I can see is that you've switched up your parameter names. So instead of result.greeting being set to "Tom", you have result.language set to "Tom."
