just follow the documentation, i think the problem with this:

AppDelegate.m

#import <FBSDKCoreKit/FBSDKCoreKit.h>

- (BOOL)application:(UIApplication *)app
            openURL:(NSURL *)url
            options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
  return [[FBSDKApplicationDelegate sharedInstance]application:app
                                                       openURL:url
                                                       options:options];
}

@prih The AppDelegate.m implementation is same. The issue is with iOS version 13 and above. Is there any new integration to be done for iOS 13 and above?

[prih]

@Poojapandey89 tested this on 13.6.1 everything is ok, after change AppDelegate.m

@Poojapandey89 Anyone got solution for this?

[Poojapandey89]

@JeyShah Updated the AppDelegated.m File with-
AppDelegate.m

• (BOOL)application:(UIApplication *)app
  openURL:(NSURL *)url
  options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
  {
  return [[FBSDKApplicationDelegate sharedInstance]application:app
  openURL:url
  options:options];
  }

I think the following code, mentioned by @prih and @Poojapandey89, is missing or not updated in iOS Quick Start documentation.

// Code A
- (BOOL)application:(UIApplication *)app
            openURL:(NSURL *)url
            options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
  return [[FBSDKApplicationDelegate sharedInstance]application:app
                                                       openURL:url
                                                       options:options];
}

Quick start requests to include the following code, which is different from the above code(Code A):

// Code B
- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
  return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                         openURL:url
                                               sourceApplication:sourceApplication
                                                      annotation:annotation];
}

Now Xcode 12.2 shows the method(Code B) in Quick Start is deprecated, as shown below:

I added Code A to my AppDelegate.m and now facebook login completes normally.
Thanks @prih and @Poojapandey89 .

By the way, my method definition was slightly different:

- (BOOL)application:(UIApplication *)application
   openURL:(NSURL *)url
   options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
  return [RCTLinkingManager application:application openURL:url options:options];
}

I replaced return [RCTLinkingManager application:application openURL:url options:options];
with

  return [[FBSDKApplicationDelegate sharedInstance]application:application
                                                       openURL:url
                                                       options:options];

Any updates for this issue? I've used @prih and @Poojapandey89 codes and it's still not working, stuck at the webview after logging in on FB app.

@HerbertLim thank you so much for your answer, my case was exactly that. I had the deprecated warning and was implementing the new method but for other linking related stuff so I had to merge what I had with this facebook bit on the new method and it worked like a charm!
