What is wrong?
// Enter your code below
func coordinates(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)
}
}

28,558 PointsThe instructions specify that the location
parameter should have an external name of for
. If you add that like this:
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)
}
}
Then your code will pass the challenge.

28,558 Pointsfor
is a keyword in Swift. Keywords generally can't be used as names without being escaped, but parameter names are an exception to that rule. For parameter names anything other thaninout
,var
andlet
can be used as names.If you want more info you can read though the official documentation on Swift Keywords.
