What am I missing? Code works in Xcode but won't pass.

Does anyone know why this isn't passing? I looked at other solutions, and one of them seems identical to mine, but I can't get this one to pass. It works in Xcode.

Also, why is (0,0) acceptable for the default return case (per the instructions)? Doesn't the function need to return a Tuple of Doubles?

functions.swift 
// Enter your code below
func coordinates(for location: String) -> (Double, Double) {
    switch location {
    case "Eiffel Tower":
        return(48.8582, 2.2945)
    case "Great Pyramid":
        return(29.9792, 31.1344)
    case "Syney Opera House":
        return(33.8587, 151.2140)

    default:
        return(0,0)
    }
}

Hi there! Nope, this will not create an error in Xcode. Check very closely your spelling of "Sydney Opera House". You've accidentally typed "Syney" instead of "Sydney". You missed a "d" in there. Other than that, you're doing terrific!

Hope this helps! :sparkles:

I could be mistaken here, but I believe there's an implicit conversion from Int to Double in that default. :smiley:

The implicit conversion is ok, though. The compiler is fine with it, and I like the style imo
