Not sure why this is not passing?

Works as expected in the playground - help :-/

functions.swift
// Enter your code below
func getTowerCoordinates(location: String) -> (lat: Double, lng: Double){
    switch location {
        case "Eiffle 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)
    }
}

Hey Michael Peritore,

Two things. First you misspelled "Eiffel" in "Eiffel Tower". This is one of the many dangers of working with Strings :) Second, you do not need to name the components of the tuple. The challenge doesn't want you to nor does it make sense if you aren't using the names for something.

// Enter your code below
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)
    }
}

Good Luck!

You'll get used to reading every single word for the slightest mistake. One character is all it takes to break the code. No speed reading!
