Swift, CLLocationManagerDelegate in NSObject not working - swift

Question

i have problem with getting my location with CLLocationDelegate.
i created new subclass of UIView and work well, but when i created subclass of NSObject, CLLocationDelegate not called. I can find where is problem.
here is my code:
import UIKit
import CoreLocation
class LocationData: NSObject, CLLocationManagerDelegate {
var locationManager : CLLocationManager = CLLocationManager()
override init() {
super.init()
if self.locationManager.respondsToSelector(Selector("requestAlwaysAuthorization")) {
self.locationManager.requestWhenInUseAuthorization()
}
self.locationManager.delegate = self
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
self.locationManager.distanceFilter = 50
self.locationManager.startUpdatingLocation()
println("init LocationData")
}
func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
println(error.description)
}
func locationManager(manager: CLLocationManager!, didUpdateToLocation newLocation: CLLocation!, fromLocation oldLocation: CLLocation!) {
println("updated")
}
}
Thanks!

Your code is fine! But when instantiating the class, you need to do like this:
import UIKit
class ViewController: UIViewController {
let LocationData: LocationData = LocationData() //<- here is the secret to works!!!
override func viewDidLoad() {
super.viewDidLoad()
}
I also suggest that you change your init to something like this:
override init() {
super.init()
let authorizationStatus: CLAuthorizationStatus = CLLocationManager.authorizationStatus()
if authorizationStatus == .notDetermined {
locationManager.requestWhenInUseAuthorization()
}
self.locationManager.delegate = self
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
self.locationManager.distanceFilter = 50
self.locationManager.startUpdatingLocation()
print("init LocationData")
}
And don't forget to add NSLocationWhenInUseUsageDescription in the info.plist project.
