iBeacon不工作，我没有收到任何通知，日志中没有打印任何内容

Question

如果手机靠近我的笔记本电脑，我正在尝试发送通知，但我没有收到任何通知，也没有在控制台中记录任何内容。我已经完成了info.plist pre reqs NSLocationAlwaysUsageDescription和NSLocationWhenInUseUsageDescription。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    let uuidString = "A29ADC96-F6F6-478B-9D4B-0E6420FA1F71" //I used the terminal command "uuidgen"
    let beaconIdentifier = "iBeaconModules.us"
    let beaconUUID = NSUUID(UUIDString: uuidString)!
    let beaconRegion:CLBeaconRegion = CLBeaconRegion(proximityUUID: beaconUUID,
        identifier: beaconIdentifier)


    locationManager = CLLocationManager()
    if(locationManager!.respondsToSelector("requestAlwaysAuthorization")) {
        locationManager!.requestAlwaysAuthorization()
    }
    locationManager!.delegate = self
    locationManager!.pausesLocationUpdatesAutomatically = false

    locationManager!.startMonitoringForRegion(beaconRegion)
    locationManager!.startRangingBeaconsInRegion(beaconRegion)
    locationManager!.startUpdatingLocation()



    UITabBar.appearance().barTintColor = UIColorFromRGB("4B4B4B")
    UITabBar.appearance().tintColor = UIColorFromRGB("00D6B4")

    if(application.respondsToSelector("registerUserNotificationSettings:")) {
        application.registerUserNotificationSettings(
            UIUserNotificationSettings(
                forTypes: [.Alert, .Badge, .Sound],
                categories: nil
            )
        )
    }



    return true
}

func sendLocalNotificationWithMessage(message: String!, playSound: Bool) {
    let notification:UILocalNotification = UILocalNotification()
    notification.alertBody = message

    if(playSound) {

       // viewController.tableView!.reloadData()

        NSLog("didRangeBeacons");
        var message:String = ""

        var playSound = false

        if(beacons.count > 0) {
            let nearestBeacon:CLBeacon = beacons[0]

            if(nearestBeacon.proximity == lastProximity ||
                nearestBeacon.proximity == CLProximity.Unknown) {
                    return;
            }
