I cannot figure out exactly how to modify this code to return as a tuple.
func greeting(#person: String) -> (language: Bool, greeting: String) {
let language = "English"
let greeting = "Hello \(person)"
return greeting
return language
}

You're going to use the function definition as your guide. That being said, it looks like there may be a problem with your function signature! I think language is supposed to be of type String. Here's how I would write it:
//I removed the # symbol and changed the return type. Language will be a string, not a bool.
func greeting(person: String) -> (language: String, greeting: String) {
let language = "English"
let greeting = "Hello \(person)"
// Returning a tuple is easy... you just write a tuple!
return (language, greeting)
}
