How to get user's current location in Swift 2.0?

First of all, I have looked at other examples and they are not working for me. Some use a different version of swift or Xcode. And some are in objective-c. I have finished the weather app Stormy, and it uses Forecast.io and stuff. And it takes 2 values as the longitude and latitude. But one of the main features is implementing the current location. Is there anyone that can provide an easy way to retrieve the user's location via swift 2.0?

Below is some code that I had done to retrieve user current location on a previous project. Make sure before you run this code to go into your plist and add "NSLocationWhenInUseUsageDescription" of type String with any value.

Also add in your plist "NSLocationAlwaysUsageDescription" of type string with any value as well.

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate {

    @IBOutlet var map: MKMapView!

    var locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()

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

        let latitude:CLLocationDegrees = 33.828461
        let longitude:CLLocationDegrees = -117.908934
        let latDelta:CLLocationDegrees = 0.01
        let lonDelta:CLLocationDegrees = 0.01

        let span:MKCoordinateSpan = MKCoordinateSpanMake(latDelta, lonDelta)

        let location: CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)

        let region:MKCoordinateRegion = MKCoordinateRegionMake(location, span)

        map.setRegion(region, animated: true)

        let annotation = MKPointAnnotation()

        annotation.coordinate = location
        annotation.title = "Your Location"
        annotation.subtitle = "This is a subtitle"
        map.addAnnotation(annotation)

        let uilpgr = UILongPressGestureRecognizer(target: self, action: Selector("action:"))

        uilpgr.minimumPressDuration = 2
        map.addGestureRecognizer(uilpgr)
    }

    func action(gestureRecognizer: UIGestureRecognizer) {
        print("Gesture Recognized")

        let touchPoint = gestureRecognizer.locationInView(self.map)

        let newCoordinate:CLLocationCoordinate2D = map.convertPoint(touchPoint, toCoordinateFromView: self.map)

        let annotation = MKPointAnnotation()

        annotation.coordinate = newCoordinate
        annotation.title = "New Place"
        annotation.subtitle = "One day I will own a big house"
        map.addAnnotation(annotation)
    }
//this function moves the map
    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        print(locations)

        let userLocation: CLLocation = locations[0]
        let latitude = userLocation.coordinate.latitude
        let longitude = userLocation.coordinate.longitude
        let latDelta:CLLocationDegrees = 0.01
        let lonDelta:CLLocationDegrees = 0.01

        let span:MKCoordinateSpan = MKCoordinateSpanMake(latDelta, lonDelta)

        let location: CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)

        let region:MKCoordinateRegion = MKCoordinateRegionMake(location, span)

        self.map.setRegion(region, animated: true)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

But you set the location, I need just the coordinates of the user's current location.

Hello :

You can do something like this.

import CoreLocation

class ViewController: UIViewController {

    // CoreLocation  Instance
    let locationManager = CLLocationManager()

    override func viewDidLoad(){
        super.viewDidLoad()
        findMyLocation()
    }

    // Helper Method

    func findMyLocation() {
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
        locationManager.requestWhenInUseAuthorization()

        // Here we start locating
        locationManager.startUpdatingLocation()
    }

}

// We adopt the CLLocationManagerDelegate
extension ViewController: CLLocationManagerDelegate {

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

        for location in locations {
            print("THIS IS THE LOCATION \(location.coordinate.latitude)")
        }

        // This will stop updating the location.
        locationManager.stopUpdatingLocation()
    }
}

This will get you somewhere ;)

Good luck

Do I need to add something to info.plist? Because this is not working
