I attempting to use a Touple, However, for some reason I cannot get it right.

I have tried to use multiple methods but I cannot get this Tuple correct. This is my current form of how I have it.

functions.swift 
// Enter your code below
func getTowerCoordinates(location: String) -> Double {
let lat = 0.00
let long = 0.00
    switch location {
    case "Eiffel Tower": (lat = 48.8582, long = 2.2945)
    case "Great Pyramid": (lat = 29.9792, long = 31.1344)
    case "Sydney Opera House": (lat = 33.8587, long = 151.2140)
    default: (lat = 0, long = 0)
}
return (lat, long)
}

Try returning a Tuple in your method. You are currently only returning 1 Double. 

// Enter your code below
func getTowerCoordinates(location: String) -> (Double, Double) {
    var lat = 0.00
    var long = 0.00
    switch location {
    case "Eiffel Tower": (lat = 48.8582, long = 2.2945)
    case "Great Pyramid": (lat = 29.9792, long = 31.1344)
    case "Sydney Opera House": (lat = 33.8587, long = 151.2140)
    default: (lat = 0, long = 0)
    }
    return (lat, long)
}
