After some research i got to know that jsBundleURLForBundleRoot:fallbackResource: no longer exists on RCTBundleURLProvider.
Fix:
Replace
return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
to
return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index"];
Rebuild the app. and you are good to go.
As I wasn't able to find any solution on StackOverflow and it is our first go-to place to look for any issue. So, I decided to write this answer here.
