Estoy programando nuevas notificaciones en iOS10, así:

func scheduleNotification (event : Meeting, todaysBadgeCounter: Int) {

    if #available(iOS 10.0, *) {

        let minutesBefore = 10
        //interval in seconds from current point in time to notification
        let interval : NSTimeInterval = NSTimeInterval(secondsFromNowTo(event.startTime.dateByAddingTimeInterval(-minutesBefore * 60)))

        //only schedule in the future
        if(interval > 0){


            let category = NotificationsController.notificationCategory

            let center = NotificationsController.notificationCenter
            center.setNotificationCategories([category])
            let content = UNMutableNotificationContent()

            content.title = NSString.localizedUserNotificationStringForKey(event.title, arguments: nil)
            if(minutesBefore <= 1){
                content.body = NSString.localizedUserNotificationStringForKey("IOS10: Your \(event.title) is about to start", arguments: nil)
            }else{
                content.body = NSString.localizedUserNotificationStringForKey("IOS10: You have \(event.title) in \(Int(minutesBefore)) minutes", arguments: nil)

            }
            content.sound = UNNotificationSound.defaultSound()

            let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: interval, repeats: false)
            let identifier = NSString.localizedUserNotificationStringForKey("sampleRequest\(event.UUID)", arguments: nil)
            let request = UNNotificationRequest.init(identifier: identifier, content: content, trigger: trigger)

            //setting the delegate
            center.delegate = self

            center.addNotificationRequest(request, withCompletionHandler: { (error) in
                // handle the error if needed
                log.error(error?.localizedDescription)
                print("SCHEDULING >=iOS10:", event.title, ", interval:", interval)
            })
        }


//return category
@available(iOS 10.0, *)
class var notificationCategory : UNNotificationCategory {
    struct Static {
        static let callNow = UNNotificationAction(identifier: NotificationActions.callNow.rawValue, title: "Call now", options: [])
        static let clear = UNNotificationAction(identifier: NotificationActions.clear.rawValue, title: "Clear", options: [])
        static let category : UNNotificationCategory = UNNotificationCategory.init(identifier: "CALLINNOTIFICATION", actions: [callNow, clear], intentIdentifiers: [], options: [])

    }
    return Static.category
}

Puedo programar notificaciones y recibir notificaciones locales en el momento adecuado.PERO: mis métodos de delegado que utilicé de acuerdo con el tutorial nunca se ejecutan, sin embargo, didReceiveLocalNotification se ejecuta cada vez que toco la notificación:

extension NotificationsController: UNUserNotificationCenterDelegate {

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {

    print("IOS10 delivered")

    // Response has actionIdentifier, userText, Notification (which has Request, which has Trigger and Content)
    switch response.actionIdentifier {
    case NotificationActions.NotifyBefore.rawValue:
        print("notify")
        break

    case NotificationActions.callNow.rawValue:
        print("callNow")
        break
    case NotificationActions.clear.rawValue:
        print("clear")
    default: break
    }
}

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {

        // Delivers a notification to an app running in the foreground.
        print("IOS10 delivered 2222")

    }
}

¿No se desactivó didReceiveLocalNotification? ¿Cómo hacer que se llame a estos métodos?

ACTUALIZAR:

Actualicé mi código con algunas sugerencias de aquí, a saber:

Agregué la asignación de UNUserNotificationCenter.delegate a la aplicaciónDidFinishLaunchingWithOptions.También intenté mover estos métodos (métodos delegados) fuera de la extensión a la clase NotificacionesController.swift, y establecer esta clase como UNUserNotificationCenterDelegate. Tampoco funcionó para mí.
