iOS Swift Functions and Optionals Parameters and Tuples Tuples

My function returns a tuple that includes both "language and greeting." I have no compiling issues. What am I missing?

?

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

    var tuple = (greeting, language)


    return tuple

}

Thanks, that was it. I had tried just including them in the return result instead of creating the tuple variable, but did not name the return parameters.

Hi Cameron,

1) Try naming the return parameters 'greeting' and 'language' in your function header. This will name them in the tuple.

2) Instead of creating a variable named tuple, you can return the values of both of those constants by use of parentheses in your return statement. (Although this isn't necessary, it lessens the number of lines in the code, and eliminates an extra step.)

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

    return (greeting, language)
}

Hope this helps!
