Integrate without CocoaPods

First Read Firebase Doc. => Firebase Doc

1. Register project on Firebase here => Register Project here

2. Get GoogleService-Info.plist file from here=> project=> settings => General

3. GoogleService-Info.plist file drop in your project.

4. set Notification .p12 Certificates (Production and Development) in Firebase => project=> settings => Cloud Messaging

5. Download Firebase SDK here => Firebase SDK Download

6. Create SDK folder in your project and Drop all SDK Folder in it.

7. Now Add this Framework in your Xcode => libicucore.tbd

8. Set Background Modes ON in Xcode => Projects => Capabilities => Background Mode ON => RemoteNotification

In Objective-c your Appdelegate.m file

#import "AppDelegate.h"
#import "Firebase.h"
#import "AFNHelper.h"

@interface AppDelegate (){
    
    NSString *InstanceID;
}
@property (nonatomic, strong) NSString *strUUID;
@property (nonatomic, strong) NSString *strDeviceToken;
@end
@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    UIUserNotificationType allNotificationTypes =
    (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
    UIUserNotificationSettings *settings =
    [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    [[UIApplication sharedApplication] registerForRemoteNotifications];

    [FIRApp configure];
   
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(tokenRefreshNotification:) name:kFIRInstanceIDTokenRefreshNotification object:nil];
    
    return YES;
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
    
    NSLog(@"Message ID: %@", userInfo[@"gcm.message_id"]);
    [[FIRMessaging messaging] appDidReceiveMessage:userInfo];
    
    NSLog(@"userInfo=>%@", userInfo);
}
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    
    [[FIRInstanceID instanceID] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeProd];
    NSLog(@"deviceToken1 = %@",deviceToken);
    
}
- (void)tokenRefreshNotification:(NSNotification *)notification {
   NSLog(@"instanceId_notification=>%@",[notification object]);
    InstanceID = [NSString stringWithFormat:@"%@",[notification object]];
   
 [self connectToFcm];  
}

- (void)connectToFcm {
    
    [[FIRMessaging messaging] connectWithCompletion:^(NSError * _Nullable error) {
        if (error != nil) {
            NSLog(@"Unable to connect to FCM. %@", error);
        } else {
            
            // you can send your token here with api or etc.... 
                   
        }
}
