  1. Your first error is you have names for your return value (lat1, long1) are not needed, the challenge specifically states that you do not need name for return values. You can remove them everywhere in your code
  2. You do not need the return value at the bottom of your code; the default in the switch statement handles that.

Review the correct code below and let me know if you have any questions

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)
    default:
        return(0,0)
    }
