You write them after the case. For example if the case is "Eiffel Tower" return the coordinates 48.8582 and 2.2945. Like this:

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)
    }
}
