Swift + CLGeocoder to get address from current location

First of all add & Import CoreLocation framework in your class.

If you are working with iOS 8 you must include the NSLocationAlwaysUsageDescription key in info.plist file of your current project to get the location services to work.

import UIKit

import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate

{

    let locationManager = CLLocationManager()

    

    override func viewDidLoad()

    {

        super.viewDidLoad()

        

      }

    override func didReceiveMemoryWarning()

    {

        super.didReceiveMemoryWarning()

       

    }

  

        //--- Find Address of Current Location ---//

    @IBAction func findMyLocation(sender: AnyObject)

    {

        locationManager.delegate = self

        locationManager.desiredAccuracy = kCLLocationAccuracyBest

        locationManager.requestAlwaysAuthorization()

        locationManager.startUpdatingLocation()

        

        

       let location = self.locationManager.location

        

        var latitude: Double = location.coordinate.latitude

        var longitude: Double = location.coordinate.longitude

        

        println("current latitude :: \(latitude)")

        println("current longitude :: \(longitude)")

        

    }

   You have to override CLLocationManager.didUpdateLocations (part of CLLocationManagerDelegate) to get notified when the location manager retrieves the current location:

    func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!)

    {

                 //--- CLGeocode to get address of current location ---//

        CLGeocoder().reverseGeocodeLocation(manager.location, completionHandler: {(placemarks, error)->Void in

            

            if (error != nil)

            {

                println("Reverse geocoder failed with error" + error.localizedDescription)

                return

            }

            

            if placemarks.count > 0

            {

                let pm = placemarks[0] as CLPlacemark

                self.displayLocationInfo(pm)

            }

            else

            {

                println("Problem with the data received from geocoder")

            }

        })        

    }

    func displayLocationInfo(placemark: CLPlacemark?)

    {

        if let containsPlacemark = placemark

        {

            //stop updating location to save battery life

            locationManager.stopUpdatingLocation()

            

            let locality = (containsPlacemark.locality != nil) ? containsPlacemark.locality : ""

            let postalCode = (containsPlacemark.postalCode != nil) ? containsPlacemark.postalCode : ""

            let administrativeArea = (containsPlacemark.administrativeArea != nil) ? containsPlacemark.administrativeArea : ""

            let country = (containsPlacemark.country != nil) ? containsPlacemark.country : ""

            

            println(locality)

            println(postalCode)

            println(administrativeArea)

            println(country)

        }

        

    }

    

    func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!)

    {

        println("Error while updating location " + error.localizedDescription)

    }

}
