Plugin Version
cordova-plugin-firebase 2.0.5 "Google Firebase Plugin"

Additional context
My app delegate

#import "AppDelegate.h"
#import "MainViewController.h"

@implementation AppDelegate



- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{    
    self.viewController = [[MainViewController alloc] init];
    return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

I use:
https://beta.ionicframework.com/docs/native/firebase

question: it's normal that this plugin not usa pod? my pod it's empty

I had the same problem and it seems to be caused by the fact that your project/workspace is build using the new build system instead of the legacy one.

See for example following comment how to change this setting:
