Navigation.registerComponent('main.AppScreen', () => App);

  Navigation.setRoot({

You've missed the installation parts with AppDelegate.m file

@oviedo97fer I have the same issue on Android and RNN 3.3.0 (and all v3 versions apparently). I'm running with RN 0.61.3.

Did you find a solution?

I had this issue, in my own case i was doing everything in AppDelegate.m file but there was a bridging code so i had to remove it.

Comment out this line of code

`RCTBridge *bridge = [[RCTBridge alloc] initWithDelegate:self launchOptions:launchOptions];
RCTRootView *rootView = [[RCTRootView alloc] initWithBridge:bridge
moduleName:@"raajneti"
initialProperties:nil];

rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];

self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
UIViewController *rootViewController = [UIViewController new];
rootViewController.view = rootView;
self.window.rootViewController = rootViewController;
[self.window makeKeyAndVisible];`
