Compiles, and works exactly as expected in Swift

Once again, I'm entering code that satisfies all challenge requirements, compiles in the treehouse compiler, compiles in Xcode, returns the expected values in Xcode, but does not pass the challenge. What am I missing here?

functions.swift 
// Enter your code below

func coordinates(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)
    }
}

You are missing the external name that the question specifies "with an external name for"

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

coordinates(for: "Eiffel Tower")

Thanks very much, using the keyword 'for' as a name threw me... I thought it might be a typo. I tried using it in my statement initially but had a syntax error elsewhere. I thought using a keyword for a name would cause a compiler error. Definitely doesn't seem like best practice to me...

I had the same question from another person but using the for is not a problem
