CLLocation Manager in Swift to get Location of User

Question

I am trying to convert an old app in ObjC to Swift as a practice exercise and have ran in to some issues. The way I had it in the old app, it was establishing the CLLocation Manager and then I would use:

manager = [[CLLocationManager alloc]init]; manager.delegate = self; manager.desiredAccuracy = kCLLocationAccuracyBest;     [manager startUpdatingLocation] 

which would call automatically:

-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{ } 

and from there I could extract all the information I needed. But in swift, there is no autocompletion of this method and I cannot figure out how to reproduce it. The documentation says that

startUpdatingLocation() 

will still be called by the delegate, but it isn't happening.

This is what I have so far:

import UIKit import corelocation  class ViewController: UIViewController,CLLocationManagerDelegate{  @IBOutlet var gpsResult : UILabel  var manager:CLLocationManager!  override func viewDidLoad() {     super.viewDidLoad()     // Do any additional setup after loading the view, typically from a nib.      manager = CLLocationManager()     manager.delegate = self     manager.desiredAccuracy = kCLLocationAccuracyBest     manager.startUpdatingLocation() }  func locationManager(manager:CLLocationManager, didUpdateLocations locations:AnyObject[]) {     println("locations = \(locations)")     gpsResult.text = "success" } } 

Any help or pointers on where to look would be appreciated. Thanks.

EDIT: Updated from Suggestions, but still not working

EDIT2: Seems to be some bug not allowing the method to work properly in the ViewController

Answer 1

You are missing two things. First, you have to ask for permission using requestAlwaysAuthorization or requestWhenInUseAuthorization(). So your viewDidLoad() should be like this:

var locationManager = CLLocationManager()  override func viewDidLoad() {     super.viewDidLoad()     // Do any additional setup after loading the view, typically from a nib.      locationManager.delegate = self     locationManager.desiredAccuracy = kCLLocationAccuracyBest     locationManager.requestAlwaysAuthorization()     locationManager.startUpdatingLocation() } 

Second, edit your Info.plist as indicated here.

Answer 2

First add this two line in plist file

1. NSLocationWhenInUseUsageDescription

2. NSLocationAlwaysUsageDescription

Then this is class working complete implement this

import UIKit  import CoreLocation  @UIApplicationMain  class AppDelegate: UIResponder, UIApplicationDelegate, CLLocationManagerDelegate {  var window: UIWindow? var locationManager: CLLocationManager! var seenError : Bool = false var locationFixAchieved : Bool = false var locationStatus : NSString = "Not Started"  func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {     initLocationManager();     return true }  // Location Manager helper stuff func initLocationManager() {     seenError = false     locationFixAchieved = false     locationManager = CLLocationManager()     locationManager.delegate = self     locationManager.locationServicesEnabled     locationManager.desiredAccuracy = kCLLocationAccuracyBest      locationManager.requestAlwaysAuthorization() }  // Location Manager Delegate stuff // If failed func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {     locationManager.stopUpdatingLocation()     if (error) {         if (seenError == false) {             seenError = true            print(error)         }     } }  func locationManager(manager: CLLocationManager!, didUpdateLocations locations: AnyObject[]!) {     if (locationFixAchieved == false) {         locationFixAchieved = true         var locationArray = locations as NSArray         var locationObj = locationArray.lastObject as CLLocation         var coord = locationObj.coordinate          println(coord.latitude)         println(coord.longitude)     } }  // authorization status func locationManager(manager: CLLocationManager!,     didChangeAuthorizationStatus status: CLAuthorizationStatus) {         var shouldIAllow = false          switch status {         case CLAuthorizationStatus.Restricted:             locationStatus = "Restricted Access to location"         case CLAuthorizationStatus.Denied:             locationStatus = "User denied access to location"         case CLAuthorizationStatus.NotDetermined:             locationStatus = "Status not determined"         default:             locationStatus = "Allowed to location Access"             shouldIAllow = true         }         NSNotificationCenter.defaultCenter().postNotificationName("LabelHasbeenUpdated", object: nil)         if (shouldIAllow == true) {             NSLog("Location to Allowed")             // Start location services             locationManager.startUpdatingLocation()         } else {             NSLog("Denied access: \(locationStatus)")         } } }
