}
whats might be the issues here for that crash ? Cordinates - lat,long is not passed or issues is with func getAdressName(coords: CLLocation)

Answer 1

Replace your getAdressName with below code.
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.name != nil {
adressString = adressString + place.name! + " - "
}
if place.subLocality != nil {
adressString = adressString + place.subLocality! + ", "
}
if place.subAdministrativeArea != nil {
adressString = adressString + place.subAdministrativeArea! + " - "
}
if place.country != nil {
adressString = adressString + place.country!
}
self.Userdic.setValue(adressString, forKey: "useraddress")
self.userAdd = adressString
}
}
}
}
You checking the nil of locality but inside getting the value of place.subAdministrativeArea! which might in nil case.
