react-native: It is not possible anymore to hot reload or debug on a real device

Issue Description

I want to debug an app on my iPhone but when i press the ‘Debug JS Remotely’ it crashes with the error ‘’ and the button ‘Hot Reload’ is not even visible.

It seems like the packager is building always a pre built bundle of the app. There is no ‘loading from xy’ message at the top anymore and the build phase ‘Bundle React Native code and images’ inside Xcode takes really long.

                                                     launchOptions:launchOptions];

    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    UIViewController *rootViewController = [[UIViewController alloc] init];
    rootViewController.view = rootView;
    self.window.rootViewController = rootViewController;
    [self.window makeKeyAndVisible];
    return YES;
}

@end

Expected Results

Debug with Google Chrome and use the hot reload feature.
