Functions.Swift Quiz, Switch inside of Function.

I have everything down except the return value. I don't know what I am so posed to put after the return command.

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

    }

Hey Israel Bracey,

You need a return inside of each case statement. This way when a case statement is matched, the value specified for that case will be returned. You also need to change your return type to match the value you are returning in your case statements. You are returning a tuple of (Double, Double).

// Enter your code below
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)
      }
 }

Good Luck
