task 1 states: Make sure to name each item in the tuple: greeting and language

Its not entirely clear but greeting needs to be the first element in the tuple and language second. change your return type and the return tuple around. also be sure that you close the function after the return and the the result constant is created outside of the function scope

// change the return type so that greeting is first, and language second
func greeting(person: String) -> (greeting: String, language: String) {
    let language = "English"
    // make the greeting the first element, and language second
    var greeting = ("Hello \(person)", language )

    return greeting
} //close the function

let result = greeting("Tom")

Wow another speedy response - thanks so much and love the service and help! Would be nice if they specified the order needed. It was working in x-code fine for me so that's why I was pretty confused :)
