Swift 3 - Functions Challenge

Hi there,

Can someone please help me with this problem?

functions.swift 
//Enter your code below 
func getTowerCoordinates(location: String) -> (Double, Double) {

    var lat: Double = 0.0, lon: Double = 0.0

    switch location {
    case "Eiffel Tower": lat = 48.8582; lon = 2.2945
    case "Great Pyramid": lat = 29.9792; lon = 31.1344
    case "Sydney Opera House": lat = 33.8587;  lon = 151.2140
    default: return (0,0)
    }

return (lat, lon)
}

First in the directions you were told to name the function coordinates so change it to that and you were also told to add an external name for the parameter which is "for". The correct code is:

func coordinates(for location: String) -> (Double, Double) {

var lat: Double = 0.0, lon: Double = 0.0

switch location {
case "Eiffel Tower": lat = 48.8582; lon = 2.2945
case "Great Pyramid": lat = 29.9792; lon = 31.1344
case "Sydney Opera House": lat = 33.8587;  lon = 151.2140
default: return (0,0)
}

return (lat, lon) }
