Can someone please explain why my code doesn't work?

It works for me in Xcode, but for some reason it won't work when I enter it into the Treehouse compiler. I don't get any error messages in the "Preview" window, but I do get a Bummer error message that says "Make sure you are returning the correct values for each case statement." Here's my code:

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 "Syndy Opera House": return (33.8587, 151.2140)
        default: return (0, 0)
    }
}

You did not spell Sydney correctly!

case "Sydney Opera House" : return (33.8587, 151.2140)

I was able to pass the challenge with this version:

var eiffelTower: (Double, Double) = (lat: 48.8582, lon: 2.2945)
var greatPyramid: (Double, Double) = (lat: 29.9792, lon: 31.1344)
var sydneyOperaHouse: (Double, Double) = (lat: 33.8587, lon: 151.2140)

func getTowerCoordinates(location: String) -> (Double, Double) {
    switch location{
        case "Eiffel Tower": return eiffelTower
        case "Great Pyramid": return greatPyramid
        case "Sydney Opera House": return sydneyOperaHouse
    default: return (0,0)
    }
}
