I am sure that I have done this test correctly but you keep telling me that I have not!

I have developed this in a Playground and get the right answer so....???

functions.swift 
// Enter your code below
func getTowerCoordinates(location: String) -> (lat: Double, lon: Double) {
    //Eiffel Tower = 48.8582, 2.2945
    //Great Pyramid = 29.9792, 31.1344
    //Sydney Opera House = 33.8587, 151.2140
    var lat: Double = 0
    var lon: Double = 0
    switch location {
        case "Eiffel Tower": (lat = 48.8582, lon = 2.2945)
        case "Great Pyramid":(lat = 29.9792, lon = 31.1344)
        case "Sydney Opera House":(lat = 33.8587, lon = 151.2140)
    default: (0,0)

    }
    return (lat, lon)
}

I don't think it likes that you added variable names to the tuple. Try just returning a plain old (Double, Double) from the function.
