57,712 PointsHi there,
To make the method return something, you need to add a -> to the declaration. That also states what is being returned, so that's -> String in this case.
Then you need to use the return keyword to make that happen inside the code:
func greeting(person: String) -> String {
return "Hello \(person)"
}
Hope that makes sense.
Steve.

Treehouse TeacherIf you're returning ("Hello (person)"), i.e, you're wrapping the string in parentheses, then you're returning a tuple containing a String, and not a String. Remove the parentheses to return a String.
