Local notification on Region Monitoring for Swift

Hi folks, im working on a project where I would like to receive a Local notification when the user enters or exits a region.

So far, only the console prints the NSLogs when i enter or exit. All the code is written within the viewcontroller.

ANY help would be greatly appreciated, Fernando

    @IBAction func regionMonitoring(sender: AnyObject) {
        manager?.requestAlwaysAuthorization()

        let notreDame = CLCircularRegion(center: CLLocationCoordinate2D(latitude: 48.858400, longitude: 2.294500), radius: 200, identifier: "notreDame")
        manager?.startMonitoringForRegion(notreDame)

    }

    func locationManager(manager: CLLocationManager, didEnterRegion region: CLRegion) {

        let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge , .Sound], categories: nil)
        UIApplication.sharedApplication().registerUserNotificationSettings(settings)

        let notification = UILocalNotification()
        notification.region = region
        notification.alertBody = "Hello this should popUp" // text that will be displayed in the notification
        NSLog("Entering region")

    }

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

Everything is working as it should. UILocalNotification will only pop to your screen if your app is running in the background. If you want the user to be notified while they are on the app as well, you would need to include an alertController.

let alertController = UIAlertController(title: "In Region", message: "Your in NotreDame!", preferredStyle: .Alert)
        let defaultAction = UIAlertAction(title: "OK", style: .Default, handler: nil)
        alertController.addAction(defaultAction)
        presentViewController(alertController, animated: true, completion: nil)
