无法连接 Firebase [IOS/Swift]

Question

I encountered a weird problem trying to connect with firebase in my project. I already followed all necessary steps - firebase config, cocopod, google.plist - but I keep getting these error messages in this screenshot. Does anyone else encounter this problem and how did you resolve it?

AppDelegate

import UIKit
import Firebase

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    FirebaseApp.configure()
    return true
}

Answer 1

1- I think everything is going well but it's appearing in the error that you may have a poor connection " Could not connect to the server " My advice is to try it again and make sure from google Plist that it's documented under the same bundle identifier

2- If the previous doesn't work, just try to update the pod

3- In the worst case try to uninstall it & install it again
