Follow steps

1) Import Firebase and FirebaseAuth

import Firebase import FirebaseAuth

2) In didFinishLaunchingWithOptions Configure firebase.

FirebaseApp.configure()

3) Write these two func in AppDelegate.

  func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let firebaseAuth = Auth.auth()
    firebaseAuth.setAPNSToken(deviceToken, type: AuthAPNSTokenType.prod)

}

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    let firebaseAuth = Auth.auth()
    if (firebaseAuth.canHandleNotification(userInfo)){
        print(userInfo)
        return
    }
}

4) In your ViewController class, repeat step first and write code for send OTP on Mobile Number, which you want.

@IBAction func sendCodeAction(_ sender: Any) {
    let ugrMgr = UserManager.userManager
    let phoneNumber = Auth.auth().currentUser?.phoneNumber
    print(phoneNumber!)
    print(ugrMgr.mobile!)
    PhoneAuthProvider.provider().verifyPhoneNumber("+91" + ugrMgr.mobile!, uiDelegate: nil) { (verificationID, error) in
        if let error = error {
            print(error.localizedDescription)
            mainInstance.ShowAlertWithError(error.localizedDescription as NSString, msg: error.localizedDescription as NSString)
            return
        }
    self.verificationID = verificationID

    }

}
