Reverse Geocode Location in Swift [closed]

Question

My input is a latitude and longitude. I need to use the reverseGeocodeLocation function of swift, to give me the output of the locality. The code I have tried to use is

            println(geopoint.longitude)              println(geopoint.latitude)             var manager : CLLocationManager!             var longitude :CLLocationDegrees = geopoint.longitude             var latitude :CLLocationDegrees = geopoint.latitude              var location: CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)             println(location)              CLGeocoder().reverseGeocodeLocation(manager.location, completionHandler: {(placemarks, error) -> Void in                 println(manager.location)                  if error != nil {                     println("Reverse geocoder failed with error" + error.localizedDescription)                     return                 }                 if placemarks.count > 0 {                     let pm = placemarks[0] as CLPlacemark                       println(pm.locality)                 }                   else {                     println("Problem with the data received from geocoder")                 } 

in the logs I get

//-122.0312186 //37.33233141 //C.CLLocationCoordinate2D //fatal error: unexpectedly found nil while unwrapping an Optional value 

It seems that the CLLocationCoordinate2DMakefunction is failing, which then causes the fatal error in the reverseGeocodeLocation function. Have I mucked up the format somewhere?

Answer 1

you never reverse geocode the location but you pass in manager.location.

see: CLGeocoder().reverseGeocodeLocation(manager.location, ...

I assume that was a copy&paste mistake and that this is the issue - the code itself looks good - almost ;)

working code

    var longitude :CLLocationDegrees = -122.0312186     var latitude :CLLocationDegrees = 37.33233141          var location = CLLocation(latitude: latitude, longitude: longitude) //changed!!!     println(location)          CLGeocoder().reverseGeocodeLocation(location, completionHandler: {(placemarks, error) -> Void in         println(location)         guard error == nil else {             println("Reverse geocoder failed with error" + error.localizedDescription)             return         }         guard placemarks.count > 0 else {             println("Problem with the data received from geocoder")             return         }         let pm = placemarks[0] as! CLPlacemark         println(pm.locality)     })
