Splash screen appears below JS content when using react native navigation

I started using [RNSplashScreen showSplash]; and it was working great, however, I didn’t know that this method is blocking the thread with a while loop. This caused for some listeners and callbacks (for example, branch) to not be called only after hiding the splash screen.

After understanding this, I started using [RNSplashScreen showSplash:@"LaunchScreen" inRootView:rootView];. However, it appeared for a second but when setting the rootScreen using RNN it disappeared because the JS content appears on top of it.

In order to fix it, I did this:

_window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
_window.backgroundColor = [UIColor clearColor];
_window.userInteractionEnabled = NO;
_window.rootViewController = rootViewController;
rootViewController.view.userInteractionEnabled = NO;

[RNSplashScreen showSplash:@"LaunchScreen" inRootView: rootViewController.view];
  
[_window setHidden:NO];

And now I see the splash screen until using hide();.

Yes I created a new ui view controller.

Here is my full code

// The only way to show the splash screen over the JS ui and without blocking the thread
  rootViewController = [UIViewController new];

  _window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  _window.backgroundColor = [UIColor clearColor];
  _window.userInteractionEnabled = NO;
  _window.rootViewController = rootViewController;
  rootViewController.view.userInteractionEnabled = NO;

  [RNSplashScreen showSplash:@"LaunchScreen" inRootView: rootViewController.view];

  [_window setHidden:NO];
  
  t = [NSTimer scheduledTimerWithTimeInterval: 2.0 target: self selector: @selector(onHideSplashScreen) userInfo: nil repeats:YES];
 
  return YES;

- (void)onHideSplashScreen  {
  // I want to die for implementing this like that, but I don't have a choice right now :(
  if (rootViewController.view.subviews.count == 0) {
    [t invalidate];
    t = nil;
    [[[UIApplication sharedApplication] delegate] setWindow:mainWindow];
  }
}

and the LaunchScreen in this case is a xib that looks the same as the LunchScreen.storyboard I set up in the settings of the project
