My CoreLocation based Swift app is not asking user's permission to access location

I am building a

based app which which show user their location based on 6 parameters like Latitude, Longitude, Horizontal Accuracy, Altitude, Vertical Accuracy, Distance Traveled.

It suppose to ask user's permission to allow access of location at first time but I have tried resetting all simulator's settings too.

This is how my Main.storyboard look like

Gray part will be filled with map later.

This is how my View.Controller.swift look like:

// Created by 16246 on 6/7/16.

import UIKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {
private let LocationManager = CLLocationManager()
private var previousPoint:CLLocation?
private var totalMovementDistance:CLLocationDistance = 0

@IBOutlet var latitudeLabel: UILabel!
@IBOutlet var longitudeLabel: UILabel!
@IBOutlet var horizontalAccuracy: UILabel!
@IBOutlet var altitudeLabel: UILabel!
@IBOutlet var verticalAccuracyLabel: UILabel!
@IBOutlet var distanceTraveledLabel: UILabel!

override func viewDidLoad() {
LocationManager.delegate = self
LocationManager.desiredAccuracy = kCLLocationAccuracyBest

// Do any additional setup after loading the view, typically from a nib.

func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
print("Authorization Status Changed to \(status.rawValue)")
switch status {
case .Authorized, .AuthorizedWhenInUse:

func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
let errorType = error.code == CLError.Denied.rawValue ? "Access Denied": "Error \(error.code)"
let alertController = UIAlertController(title: "Location Manager Error", message: errorType, preferredStyle: .Alert)
let okAction = UIAlertAction(title: "OK", style: .Cancel, handler: {action in})
presentViewController(alertController, animated: true, completion: nil)

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let newLocation = (locations as [CLLocation]) [locations.count-1]

let latitudeString = String(format: "%g\u{00B0}", newLocation.coordinate.latitude)
latitudeLabel.text = latitudeString

let longitudeString = String(format: "%g\u{00B0}", newLocation.coordinate.longitude)
longitudeLabel.text = longitudeString

let horizontalAccuracyString = String(format: "%g\u{00B0}", newLocation.horizontalAccuracy)
horizontalAccuracy.text = horizontalAccuracyString

let altitudeString = String(format: "%g\u{00B0}", newLocation.altitude)
altitudeLabel.text = altitudeString

let verticalAccuracyString = String(format: "%g\u{00B0}", newLocation.verticalAccuracy)
verticalAccuracyLabel.text = verticalAccuracyString

if newLocation.horizontalAccuracy < 0 {

if newLocation.horizontalAccuracy > 100 ||
newLocation.verticalAccuracy > 50 {

if previousPoint == nil {
totalMovementDistance = 0
} else {
totalMovementDistance += newLocation.distanceFromLocation(previousPoint!)

previousPoint = newLocation

let distanceString = String(format: "%gm", totalMovementDistance)
distanceTraveledLabel.text = distanceString


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


This is my Info.plist file:

This is my Simulator:

I want output like this:

I have been stuck on this since past 2 days. Pint of beer for a geek who help me to get along with this.


Move LocationManager.requestAlwaysAuthorization() to the viewDidAppear method.
