Returning Multiple Values in a Tuple

Stuck once again... I look at this question and I don't even know where to start?

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

    return greeting 


}

A tuple is specified with parenthesis (), if you are using a tuple as a return type you can write

func myFunc() -> (String, String) {
  return ("hello", "world")
}

In this example, myFunc returns a tuple consisting of two strings, remember that tuples can have multiple values and even diferent types for each value, the return statement creates a tuple with the strings "hello" and "world", but you can replace those strings with variables as in your example.
