Hm... stuck on this one.

I know I'm close... but what am I doing wrong? It is returning an error I can't understand...

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 (Double, Double)
}

Hi Ryan,

Your switch statement is kind of a mess; that's why it's not passing. The Challenge asked you to return the latitude and longitude, like this:

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