What error are you getting exactly?

You do not need to create a dictionary (which you name array). That adds complexity they didn't want in this exercise, as you would then need to deal with optionals. You don't ned a loop either. You need to switch on the input variable location. You need to return a tuple for each case.

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)
    }
}
