Phaser Cordova Mobile App Crashing on iOS

I recently decided to compile Phaser games to iOS and publish to The App Store. The games were already published on Google Play Store for Android and worked without any issues. I faced few issues after compiling Phaser games for iOS. The first issue which I faced was the game crashing randomly on iOS. After doing further research I found this article on Intel XDK forum which turned out to be the reason for crash. The games were written a while back with older versions of Phaser and I did not get time to upgrade and test this with newer versions of Phaser (CE and higher) so I decided to try the fix specified in this thread and voila, it worked just fine.

Here is the code which I borrowed from the thread

var mygame;
window.onload = function () {
    mygame = new Phaser.Game(window.innerWidth, window.innerHeight, Phaser.AUTO, "mygame");
    mygame.state.add("Boot", Boot);
    mygame.state.add("Loading", Loading);
    mygame.state.add("MainMenu", MainMenu);
    mygame.state.add("TheGame", TheGame);
    mygame.state.start("Boot");
	
    function onPause() {
        if(!mygame.paused) {
            mygame.gamePaused();
        }
    }
  
    function onResume() {
        setTimeout(function() {
            if(mygame.paused) {
                mygame.gameResumed();
            }
        }, 0);
    }
 
    document.addEventListener('pause', onPause, false);
    document.addEventListener('resume', onResume, false);
	
}
