Fetch Location in Swift 3.0

Fetch Location

Suppose you want to fetch current location of yours location, you don’t have to use the google API’s you can fetch your exact location using CLLocationManager. steps to fetch location

• First, you have to import the CoreLocation library at the top of your view controller.
• Add Privacy – Location When In Use Usage Description in your info.plist file for user permission
• Then, Create reference of  CLLocationManager class.
  
  var locationManager = CLLocationManager()

  1	var locationManager = CLLocationManager()

• Create a button on which action you want to fetch the location and write the following code on fetching your location
  
  locationManager.desiredAccuracy = kCLLocationAccuracyBest locationManager.delegate = self locationManager.requestWhenInUseAuthorization() locationManager.startUpdatingLocation()

  1 2 3 4

  locationManager.desiredAccuracy = kCLLocationAccuracyBest locationManager.delegate = self locationManager.requestWhenInUseAuthorization() locationManager.startUpdatingLocation()

• Set the delegate for CLLocationManager
  
  class NewAddress: UIViewController , CLLocationManagerDelegate

  1	class NewAddress: UIViewController , CLLocationManagerDelegate

• After click on button delegate method of CLLocationManager will call. where you can find the location.
  
  func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { }

  1 2	func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { }

• For fetching Latitude and Longitude write the following code:-
  
  func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { self.locationManager.stopUpdatingLocation() let latestLocation = locations.last let latitude = String(format: "%.4f", latestLocation!.coordinate.latitude) let longitude = String(format: "%.4f", latestLocation!.coordinate.longitude) print("Latitude: \(latitude)") print("Longitude: \(longitude)") }

  func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {   self.locationManager.stopUpdatingLocation()           let latestLocation = locations.last   let latitude = String(format: "%.4f", latestLocation!.coordinate.latitude)   let longitude = String(format: "%.4f", latestLocation!.coordinate.longitude)   print("Latitude: \(latitude)")   print("Longitude: \(longitude)") }

• If you want to fetch your address in string form like street, city, state etc.You can use the CLGeocoder and CLPlacemark classes for fetch your location address :-
  
  func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { let latestLocation = locations.last let g = CLGeocoder() var p:CLPlacemark? g.reverseGeocodeLocation(latestLocation!, completionHandler: { (placemarks, error) in let pm = placemarks if ((pm != nil) && (pm?.count)! > 0){ // p = CLPlacemark() p = CLPlacemark(placemark: (pm?[0])!) print("Inside what is in p: \(p?.country )") print(p?.addressDictionary) print(p?.subAdministrativeArea) print(p?.subThoroughfare) print(p?.thoroughfare) print(p?.locality) print(p?.postalCode) print(p?.administrativeArea) print(p?.country) print(p?.isoCountryCode) }) }

  func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { let latestLocation = locations.last let g = CLGeocoder()     var p:CLPlacemark?     g.reverseGeocodeLocation(latestLocation!, completionHandler: {         (placemarks, error) in         let pm = placemarks         if ((pm != nil) && (pm?.count)! > 0){             // p = CLPlacemark()             p = CLPlacemark(placemark: (pm?[0])!)                              print("Inside what is in p: \(p?.country )")                 print(p?.addressDictionary)                 print(p?.subAdministrativeArea)                 print(p?.subThoroughfare)                 print(p?.thoroughfare)                 print(p?.locality)                 print(p?.postalCode)                 print(p?.administrativeArea)                 print(p?.country)                 print(p?.isoCountryCode)     }) }

• You Can also find the Latitude and Longitude from the  CLGeocoder and CLPlacemark classes. If you are having your address in string format.
  
  let address = "2nd Floor,A67, Sector 63, Noida, Uttar Pradesh 201301" let geocoder = CLGeocoder() geocoder.geocodeAddressString(address, completionHandler: {(placemarks, error) -> Void in if((error) != nil){ print("Error", error!) } if let placemark = placemarks?[0] { let coordinates:CLLocationCoordinate2D = placemark.location!.coordinate let latitude = String(format: "%.4f", latestLocation!.coordinate.latitude) let longitude = String(format: "%.4f", latestLocation!.coordinate.longitude) print("Latitude: \(latitude)") print("Longitude: \(longitude)") } else{ print("Some error occurs") } })

  let address = "2nd Floor,A67, Sector 63, Noida, Uttar Pradesh 201301" let geocoder = CLGeocoder() geocoder.geocodeAddressString(address, completionHandler: {(placemarks, error) -> Void in     if((error) != nil){         print("Error", error!)     }     if let placemark = placemarks?[0] {         let coordinates:CLLocationCoordinate2D = placemark.location!.coordinate         let latitude = String(format: "%.4f", latestLocation!.coordinate.latitude)         let longitude = String(format: "%.4f", latestLocation!.coordinate.longitude)         print("Latitude: \(latitude)")         print("Longitude: \(longitude)")     }     else{         print("Some error occurs")     } })
