Ionic 3 + Onesignal not working

Hi, I have Ionic-3 Onesingal integrated app. I had successfully created demo via this link .

http://masteringionic.com/blog/2017-01-06-implementing-push-notifications-with-ionic/

Actually I had nothing done any extra. I Just follow the manual of ionic 3 and above link
Here is a error log in my Xcode

2019-12-21 16:34:52.712714+0530 Ibphub[488:51186] [NetworkInfo] Signal strength query returned error: Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied", descriptor: <CTServiceDescriptor 0x281962460, domain=1, instance=1>

Here is app.component.ts file

import { Component } from '@angular/core';
import { NavController, Platform } from 'ionic-angular';
import { OneSignal } from '@ionic-native/onesignal';


@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {

   constructor(public navCtrl    : NavController,
               private _PLATFORM : Platform,
               private _SIGNAL   : OneSignal)
   {
      this._PLATFORM.ready()
      .then(() =>
      {
         this.triggerNotification();
      });
   }



   triggerNotification()
   {

      // Define settings for iOS
      var iosSettings = {};
      iosSettings["kOSSettingsKeyAutoPrompt"] = true;
      iosSettings["kOSSettingsKeyInAppLaunchURL"] = false;


      // Initialise plugin with OneSignal service
      this._SIGNAL.startInit(One-Signal-Application-ID-Pasted-Here, Firebase-Sender-ID-Pasted-Here).iOSSettings(iosSettings);


      // Control how OneSignal notifications will be shown when
      // one is received while your app is in focus
      this._SIGNAL.inFocusDisplaying(OneSignal.OSInFocusDisplayOption.InAppAlert);


      // Retrieve the OneSignal user id and the device token
      this._SIGNAL.getIds()
      .then((ids) =>
      {
         console.log('getIds: ' + JSON.stringify(ids));
      });


      // When a push notification is received handle
      // how the application will respond
      this._SIGNAL.handleNotificationReceived()
      .subscribe((msg) =>
      {
         // Log data received from the push notification service
         console.log('Notification received');
         console.dir(msg);
      });


      // When a push notification is opened by the user
      // handle how the application will respond
      this._SIGNAL.handleNotificationOpened()
      .subscribe((msg) =>
      {
         // Log data received from the push notification service
         console.log('Notification opened');
         console.dir(msg);
      });


      // End plugin initialisation
      this._SIGNAL.endInit();

   }

}

here is app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { ErrorHandler, NgModule } from '@angular/core';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
import { SplashScreen } from '@ionic-native/splash-screen';
import { StatusBar } from '@ionic-native/status-bar';
import { OneSignal } from '@ionic-native/onesignal';

import { MyApp } from './app.component';
import { HomePage } from '../pages/home/home';

@NgModule({
  declarations: [
    MyApp,
    HomePage
  ],
  imports: [
    BrowserModule,
    IonicModule.forRoot(MyApp)
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    HomePage
  ],
  providers: [
    StatusBar,
    SplashScreen,
    OneSignal,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]
})
export class AppModule {}

There is nothing error in code, as I think, because App runs smoothly, but xcode console shows this error and not receiving notification.

Help me guys, I am stucked with this notification process since last 1 week.
