Lahiru,

I copied and pasted your code to find the error, and I found some ways to simplify your code. The first thing I changed was the return type, taking out the names "lat" and "lon." For this purpose, we only need the return types, not names. Also, in the case of the Sydney Opera House, you used "long1" which the compiler doesn't recognize. Here is what I got: 

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)
    }
}

If you have any questions, feel free to ask.
