Hi, I already create the code, and test that's the code is works on playground but i cannot pass the challenge

herewith the code :

func getTowerCoordinates(location : String)->(Double, Double){
    //var lat:Double
    //var lon:Double

    let latlon:(Double, Double)

    switch location{
    case "Eiffel Tower":
        //lat =  48.8582
        //lon = 2.2945
        latlon =  (48.8582, 2.2945)
    case "Great Pyramid":
       // lat =  29.9792
       // lon = 31.1344
        latlon =  (29.9792, 31.1344)
    case "Sydney Opera House":
        //lat =  33.8582
        //lon = 151.2140
        latlon =  (33.8582, 151.2140)
    default:
        //lat = 0
        //lon = 0
        latlon =  (0,0)
    }

    return latlon
}

getTowerCoordinates("Eiffel Tower")
functions.swift 
// Enter your code below

func getTowerCoordinates(location : String)->(Double, Double){
    //var lat:Double
    //var lon:Double
   // var latlon = (Double, Double)

    switch location{
    case "Eiffel Tower":
        //lat =  48.8582
        //lon = 2.2945
        latlon =  (48.8582, 2.2945)
        //return (48.8582, 2.2945)
    case "Great Pyramid":
       // lat =  29.9792
       // lon = 31.1344
        latlon =  (29.9792, 31.1344)
        //return (29.9792, 31.1344)
    case "Sydney Opera House":
        //lat =  33.8582
        //lon = 151.2140
        latlon =  (33.8582, 151.2140)
        //return (33.8582, 151.2140)
    default:
        //lat = 0
        //lon = 0
        latlon = (0,0)
        //return (0,0)
    }

    //return latlon
    }

Hmmmm, maybe the problem is that you are making your defining latlon as a constant and then you are assigning it a value, which is not allowed since its a constant. Try to define latLon as a variable and see if it works:)

Hi Gaith Ali,

Thank you very much for your reply : "I Cannot pass the Challenge because i put the wrong value for the "LAT" on "Sidney Opera House" : on my answer is : Lat = 33.8582 ==== should be 33.8587

and herewith the working solution.

func getTowerCoordinatest(location : String)->(Double, Double){ let latlon:(Double, Double)

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

return latlon

}

getTowerCoordinatest("Eiffel Tower")
