Detect iBeacon when app is killed swift - ios

Question

I need to do something if iPhone detect (beacon in background) with UUID: "3E06945C-F54A-4BE4-ABB2-79764DA6AC6F" so I am trying to do this, in AppDelegate:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
application.registerUserNotificationSettings(UIUserNotificationSettings(types: [.sound, .alert], categories: nil))
initBeaconManager()
//Fabric.with([Crashlytics.self])
//Fabric.with([Appsee.self])
return true
}
func applicationWillTerminate(_ application: UIApplication) {
print("Application will terminate")
}
func applicationDidEnterBackground(_ application: UIApplication) {
isInForeground = false
isInBackground = true
extendBackgroundTime()
}
func applicationDidBecomeActive(_ application: UIApplication) {
isInForeground = true
isInBackground = false
NotificationCenter.default.post(name: NSNotification.Name(rawValue: "initCarPlaceNotification"), object: nil)
}
func extendBackgroundTime() {
if backgroundTask != UIBackgroundTaskInvalid {
// Still running
return
}
else {
backgroundTask = UIApplication.shared.beginBackgroundTask(withName: "Ranging", expirationHandler: { () in
// Background task expired by iOS
UIApplication.shared.endBackgroundTask(self.backgroundTask)
self.backgroundTask = UIBackgroundTaskInvalid
});
DispatchQueue.global(qos: DispatchQoS.QoSClass.default).async { //
if !self.isInForeground {
while true {
Thread.sleep(forTimeInterval: 1)
}
}
}
}
func initBeaconManager() {
let beaconsUUIDs = ["1":"3E06945C-F54A-4BE4-ABB2-79764DA6AC6F"]
locationManager = CLLocationManager()
if (locationManager!.responds(to: #selector(CLLocationManager.requestAlwaysAuthorization))) {
locationManager!.requestWhenInUseAuthorization()
}
locationManager!.delegate = self
locationManager!.pausesLocationUpdatesAutomatically = true
for (key, value) in beaconsUUIDs {
let beaconUUID:UUID = UUID(uuidString: value)!
let beaconRegion = CLBeaconRegion(proximityUUID: beaconUUID, identifier: "reg-\(key)")
locationManager!.startMonitoring(for: beaconRegion)
locationManager!.startRangingBeacons(in: beaconRegion)
}
locationManager!.startUpdatingHeading()
locationManager!.startUpdatingLocation()
}
extension AppDelegate {
func rangeForAllBeacons(_ beacons:[CLBeacon]) {
if beacons[0].proximityUUID == UUID(uuidString: "3E06945C-F54A-4BE4-ABB2-79764DA6AC6F") {
displayNotification("work fine..")
}
}
extension AppDelegate:CLLocationManagerDelegate {
func locationManager(_ manager: CLLocationManager, didRangeBeacons beacons: [CLBeacon], in region: CLBeaconRegion) {
if !isInForeground {
extendBackgroundTime()
}
print(beacons)
for beacon in beacons {
if beacon.rssi < -20 {
nearbyBeacons.append(beacon)
}
}
if firstRegionDetected == "" {
firstRegionDetected = region.identifier
} else if firstRegionDetected == region.identifier {
rangeForAllBeacons(nearbyBeacons)
nearbyBeacons = []
}
}
func locationManager(_ manager: CLLocationManager, didDetermineState state: CLRegionState, for region: CLRegion) {
if isInBackground {
extendBackgroundTime()
}
}
But it doesn't work. On the info.plist I use
Privacy - Location Always Usage Description
and
Privacy - Location When In Use Usage Description
