What m I doing wrong? (Complex number values)

I'm not sure what I'm doing wrong. Can somebody please explain where I'm going wrong and I'm also not sure how to return two tuple values.

functions.swift 
// Enter your code below
func getTowerCoordinates(location: String) -> (Double, Double) {


    switch location {

    case "Eiffel Tower": (48.8582, 2.2945)
    case "Great Pyramid": (29.9792, 31.1344)
    case "Sydney Opera House": (33.8587, 151.2140)

    default: (0,0)

    }

    return (0,0)

}

Try combining the default & return statement:

func getTowerCoordinates (location: String) -> (Double, Double) {
    switch location {
          case "Eiffel Tower": return (48.8582, 2.2945)
          case "Great Pyramid": return (29.9792, 31.1344)
          case "Sydney Opera House": return (33.8587, 151.2140)
          default: return (0,0)
      }
 }

Thank you it works! But I was assuming that the keyword 'return' has to be separate and outside the Switch statement. And, since we are returning two values shouldn't the return statement outside the switch statement be something like 'return (something, something)'?
