title: React Native getting blank white screen on app startup before splash
body: <p>I have developed a basic react native app, which seems working fine in android OS, but in iOS, I am getting a weird issue, that is, getting a blank screen as soon as the app loads before the splash screen.</p>
  
  <p>Here is my <code>index.js</code> file</p>
  
  <pre><code>import { AppRegistry } from 'react-native';
  import App from './App';
  import bgMessaging from './src/FCM/bgMessaging';
  AppRegistry.registerComponent('payrollApp', () =&gt; App);
  AppRegistry.registerHeadlessTask('RNFirebaseBackgroundMessage', () =&gt; bgMessaging);
  </code></pre>
  
  <p>I have also tried replacing the default xib (the welcome screen) with my splash screen, but in that case, still I am getting blank white screen between xib splash and react native splash.</p>
  
  <p>I don't know, what exactly, I am missing, or what further modifications needed.</p>
