didEnterRegion, didExitRegion not being called

Hi, I've been experimenting with region monitoring in order to show an alert or a local notification when the user is within the set region. As a first step, I added a print line to see if it works on the debug area. However, while the other lines are being printed, I'm not getting anything for didEnterRegion and didExitRegion.

I am simulating the location to be in/outside of the given region but I am having no luck. It will be great if someone could look at the code below and see what I've missed. Thank you.

import UIKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

var manager = CLLocationManager?()



    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        manager = CLLocationManager()
        let latitude: CLLocationDegrees = 48.858400
        let longitude: CLLocationDegrees = 2.294500
        let center: CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)
        let radius: CLLocationDistance = CLLocationDistance(100.0)
        let identifier: String = "Notre Dame"

        let currRegion = CLCircularRegion(center: center, radius: radius, identifier: identifier)

        manager?.distanceFilter = 10
        manager?.desiredAccuracy = kCLLocationAccuracyBest
        currRegion.notifyOnEntry = true
        currRegion.notifyOnExit = true

        manager?.requestWhenInUseAuthorization()


        manager?.delegate = self
        manager?.pausesLocationUpdatesAutomatically = true

        manager?.startMonitoringForRegion(currRegion)
        manager?.startUpdatingLocation()    


    }

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

    func locationManager(manager: CLLocationManager, didStartMonitoringForRegion region: CLRegion) {
        print("The monitored regions are: \(manager.monitoredRegions)")
    }

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        let locValue:CLLocationCoordinate2D = manager.location!.coordinate
        print("locations = \(locValue.latitude) \(locValue.longitude)")
    }

    func locationManager(manager: CLLocationManager, didEnterRegion region: CLRegion)  {
        NSLog("Entered")
    }

    func locationManager(manager: CLLocationManager, didExitRegion region: CLRegion) {
        NSLog("Exited")
    }


}

Problem solved!

This had to be called:

manager?.requestAlwaysAuthorization()

instead of : 

manager?.requestWhenInUseAuthorization()
