810 PointsWhy am I getting the error "error: use of unresolved identifier 'latLong' return latLong" in my code?
What should I do to correct this?
func coordinates(for location: String) -> (Double, Double){
let landmarks:[String:(Double, Double)]=["Eiffel Tower":(48.8582, 2.2945), "Great Pyramid":(29.9792, 31.1344), "Sydney Opera House":(33.8587, 151.2140) ]
switch location {
case "Eiffel Tower": var latLong = landmarks[location]
case "Great Pyramid": var latLong = landmarks[location]
case "Eiffel Tower": var latLong = landmarks[location]
default: var latLong = (0.0,0.0)
}
return latLong
}

Here is the solution:
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 (0.0,0.0)
}
}
