        Hi iOS devs,


        I'm developing Social networking app which includes APNS for Push notification and VoIP for Voice calls. After migrated to Xcode 11.3 and in iOS 13+ devices, sometimes the device token callback not called properly.


        func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        // APNS Token callback


        func pushRegistry(_ registry: PKPushRegistry, didUpdate pushCredentials: PKPushCredentials, for type: PKPushType) {
        // VOIP Token callback


        I tried killing the app and restarting, won't help. After some different ways, i tried turning off & on network and opened my app and then above two callbacks working for me.


        Also, I searched about this issue and most of developers suggesting to Restart device or turn off & on data/wifi.


        I don't think this could be possible solution and it's not consistently occuring in a same device. It's occuring randomly in different iOS 13+ devices mostly on fresh installation.


        Please suggest your solutions.

        Thanks in Advance,
