Complex Values Exercise

Hello, can anyone explain me what's wrong in my code? Thanks

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(getTowerCoordinates)
}

Juras, the basic problem with your code is that you need to return a tuple containing two doubles. You are returning the function itself. Try this instead:

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 (0.0,0.0)
  }
}

I know. They said you could return (0,0) for the default, but since the tuple is supposed to be two doubles, hey, why not!
