What do I return?

Compiler says it has to be Double, Double, Compiler won't take Double, Double, instructions said I don't have to declare a return value, complier says it is expecting a return for Double, Double. I is confuse.

functions.swift
// Enter your code below

func getTowerCoordinates(location: String) -> (Double, Double) {

    switch location{
    case "Eiffel Tower": (48.8582, 2.2946)
    case "Great Pyramid": (29.9792, 31.1344)
    case "Sydney Opera House": (22.8587, 151.2140)
    default: (0, 0)
    }

}

You return the latitude and longitude. Nowhere in there have you returned anything yet. Try this out.

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)
  }  
}

You simply are forgetting to return anything! You were very close on this one.
