You're doing a few things wrong. For starters, you're not returning any tuple values and to return them you put the two double values in parenthesis alongside the return keyword like so:

return (48.8582, 2.2945)

You also spelt Eiffel Tower wrong and you don't need the end return statement as the default case should return (0,0). So with those changes, this is what you should get:

func coordinates(for 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)
      return (0,0)
