func greeting(person: String) -> (String , String) { let language = "English" let greeting = "Hello (person)"
// Now what do i return?
// In the course Video he Returns a touple like this : var found = (true, "...") return found
// doing the same here : var tuple = (greetings, language) I get the error message "Your function needs to return a tuple
// with elements named 'greeting' and 'language'."
//return (greeting, language) also gets the same error //same goes for ("(greeting)","(language)")
// adding language to let greeting = "Hello (Person)","(language)") and returning it also is not the correct way
//so what is askt of me ?
return greeting }

6,913 PointsI would suggest re-watching the videos and coding along with him in Xcode. To start you need to understand what a tuple is; a tuple allows you to return multiple items, as opposed to the original code above which only returns a single string.
As the code above sits, the -> String portion of your function states that a single string will be returned. You're going to need to modify the code to allow for the greeting function to return multiple items.
For example:
-> (String, String) would return two strings -> (Int, String) would return an integer and a string etc.
