I don't know how to print out the value of the language element from the result tuple.

How do I get result to return "English" and not "Hello Tom"?

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


    return (greeting, language)
}


var result = greeting("Tom")

println(result)

Change the order of the parameters in your return statement

  return (language, greeting)

Thanks David,

I changed the order of parameters. This prints:

"(English, Hello Tom)"

I think I need it to only print:

"(English)"

How do I do that?

I think for this challenge you only need the first part of your code.

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

return (language, greeting)

}

// remove everything else

If I do that, it says: "Bummer! You need to declare a variable called 'result'."

The challenge definitely wants me to use println also.
