However, sometimes the app crashe

Answer 1

This is my code for swift 3

func getAdressName(coords: CLLocation) {

    CLGeocoder().reverseGeocodeLocation(coords) { (placemark, error) in
            if error != nil {
                print("Hay un error")
            } else {

                let place = placemark! as [CLPlacemark]
                if place.count > 0 {
                    let place = placemark![0]
                    var adressString : String = ""
                    if place.thoroughfare != nil {
                        adressString = adressString + place.thoroughfare! + ", "
                    }
                    if place.subThoroughfare != nil {
                        adressString = adressString + place.subThoroughfare! + "\n"
                    }
                    if place.locality != nil {
                        adressString = adressString + place.locality! + " - "
                    }
                    if place.postalCode != nil {
                        adressString = adressString + place.postalCode! + "\n"
                    }
                    if place.subAdministrativeArea != nil {
                        adressString = adressString + place.subAdministrativeArea! + " - "
                    }
                    if place.country != nil {
                        adressString = adressString + place.country!
                    }

                    self.lblPlace.text = adressString
                }
            }
        }
  }

You can esaily call above funcation like:

let cityCoords = CLLocation(latitude: newLat, longitude: newLon)
cityData(coord: cityCoords)
