whenI call the coordinates function the ide asks for a ;
// Enter your code below
func coordinates (of location: String) -> (Double, Double)
{
var lat = 0.0
var lon = 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: lat = 0.0; lon = 0.0
}
return (lat, lon)
}
coordinates(of: Eiffel Tower)

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)
}
} //call //coordinates(for: "Eiffel Tower")

You have some issues happening here:
- You don't need to declare the variables up at the top.
- You cannot declare multiple values for variables inside of a switch statement (which is causing the syntax error). So, where you have
lat = ... lon =inside is not correct. - The external and local parameter name being passed into the function is not what the challenge is asking for.
- The return statement should be inside of the switch statement and applied to each case separately.
I recommend reviewing the video on Switch Statements and then give this challenge another go. You are on the right track, just need to fix up a few things and correct some syntax errors. If you're still having problems, just let us know.
Keep Coding! :)
