Push Kit Not receiving pushCredentials token - ios

Question

I am new in integrating Push Kit so I am not able to receive the pushCredentials token please suggest me solution.
Below is my code :
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// For debugging
//OneSignal.setLogLevel(.LL_VERBOSE, visualLevel: .LL_NONE)
//Enable all notification type.
let notificationSettings = UIUserNotificationSettings(types: [UIUserNotificationType.alert, UIUserNotificationType.badge, UIUserNotificationType.sound] , categories: nil)
//register the notification settings
application.registerUserNotificationSettings(notificationSettings)
return true
}
extension AppDelegate {
func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
//register for voip notifications
let voipRegistry = PKPushRegistry(queue: DispatchQueue.main)
voipRegistry.desiredPushTypes = Set([PKPushType.voIP])
voipRegistry.delegate = self;
print("didRegisterUserNotificationSettings")
}
}
extension AppDelegate: PKPushRegistryDelegate {
func pushRegistry(_ registry: PKPushRegistry, didUpdate pushCredentials: PKPushCredentials, forType type: PKPushType) {
print("voip token: \(pushCredentials.token)")
}
func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, forType type: PKPushType) {
let payloadDict = payload.dictionaryPayload["aps"] as? Dictionary<String, String>
let message = payloadDict?["alert"]
//present a local notifcation to visually see when we are recieving a VoIP Notification
if UIApplication.shared.applicationState == UIApplicationState.background {
let localNotification = UILocalNotification();
localNotification.alertBody = message
localNotification.applicationIconBadgeNumber = 1;
localNotification.soundName = UILocalNotificationDefaultSoundName;
UIApplication.shared.presentLocalNotificationNow(localNotification);
}
else {
print(message)
// dispatch_async(DispatchQueue.main, { () -> Void in
//
// let alert = UIAlertView(title: "VoIP Notification", message: message, delegate: nil, cancelButtonTitle: "Ok");
// alert.show()
// })
}
NSLog("incoming voip notfication: \(payload.dictionaryPayload)")
}
func pushRegistry(_ registry: PKPushRegistry, didInvalidatePushTokenForType type: PKPushType) {
NSLog("token invalidated")
}
}
extension UIApplicationState {
//help to output a string instead of an enum number
var stringValue : String {
get {
switch(self) {
case .active:
return "Active"
case .inactive:
return "Inactive"
case .background:
return "Background"
}
}
}
}
Am I missing something please suggest.

func pushRegistry(_ registry: PKPushRegistry, didUpdate pushCredentials: PKPushCredentials, forType type: PKPushType) {
let deviceTokenString = pushCredentials.token.map { String(format: "%02.2hhx", $0) }.joined()
print("deviceTokenString \(deviceTokenString)")
}
