Step 2: Go to your app folder and then install CocoaPods

sudo gem install cocoapods

Step 3: To edit Podfile

pod 'Firebase/Core'

import UIKit
import Firebase
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate,UNUserNotificationCenterDelegate{
    
    
    var window: UIWindow?
    
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        
        
        
        //create the notificationCenter
        if #available(iOS 10.0, *) {
            // For iOS 10 display notification (sent via APNS)
            UNUserNotificationCenter.current().delegate = self
            
            let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
            UNUserNotificationCenter.current().requestAuthorization(
                options: authOptions,
                completionHandler: {_, _ in })
            
            // For iOS 10 data message (sent via FCM)
            //FIRMessaging.messaging().remoteMessageDelegate = self
            
        } else {
            // Asks the user for permission for nofications
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        }
        
        application.registerForRemoteNotifications()
        
        FirebaseApp.configure()
        
        return true
    }
    
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        var token = ""
        for i in 0.. Void) {
        
        // custom code to handle push while app is in the foreground
        print("Handle push from foreground\(notification.request.content.userInfo)")
        
        let dict = notification.request.content.userInfo["aps"] as! NSDictionary
        let d : [String : Any] = dict["alert"] as! [String : Any]
        let body : String = d["body"] as! String
        let title : String = d["title"] as! String
        print("Title:\(title) + body:\(body)")
        self.showAlertAppDelegate(title: title,message:body,buttonTitle:"ok",window:self.window!)
        
    }
    
    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        // if you set a member variable in didReceiveRemoteNotification, you  will know if this is from closed or background
        print("Handle push from background or closed\(response.notification.request.content.userInfo)")
    }
    
    func showAlertAppDelegate(title: String,message : String,buttonTitle: String,window: UIWindow){
        let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertController.Style.alert)
        alert.addAction(UIAlertAction(title: buttonTitle, style: UIAlertAction.Style.default, handler: nil))
        window.rootViewController?.present(alert, animated: false, completion: nil)
    }
    // Firebase ended here
    
}

Step 7: Drag the GoogleService-Info.plist into Xcode

Project fails with “Non-portable path to file ‘<protobuf/Any.pbobjc.h>'”

error which is due to Podfile is treating all warnings as errors.

Just remove the prefix and the error will go away
