Не удается получить регистрационный токен FCM

Я новичок в iOS. Я использую firebase для push-уведомлений iOS, и я использую цель c. Согласно руководству по firebase, я получаю уведомления правильно на заднем и переднем плане. Теперь я хочу, чтобы регистрационные токены создавали группы устройств для уведомлений. Итак, я не получаю регистрационный токен, как я могу это сделать, вот мой код.

#import "AppDelegate.h"
@import Firebase;
@import FirebaseMessaging;
@import FirebaseInstanceID;
//#import <FirebaseMessaging/FirebaseMessaging.h>

//@import FirebaseMessaging;
@import UserNotifications;

//@import FirebaseMessaging;
@interface AppDelegate ()<UNUserNotificationCenterDelegate,FIRMessagingDelegate>

@end

@implementation AppDelegate

NSString *const kGCMMessageIDKey = @"gcm.message_id";

   // [FIRMessaging messaging].delegate=self;
    // [END set_messaging_delegate]

    if ([UNUserNotificationCenter class] != nil) {
        // iOS 10 or later
        // For iOS 10 display notification (sent via APNS)
        [UNUserNotificationCenter currentNotificationCenter].delegate = self;
        UNAuthorizationOptions authOptions = UNAuthorizationOptionAlert |
        UNAuthorizationOptionSound | UNAuthorizationOptionBadge;

         completionHandler:^(BOOL granted, NSError * _Nullable error) {

         }];
    } else {
        // iOS 10 notifications aren't available; fall back to iOS 8-9 notifications.
