🎉🎉🎉Resolved this issue successfully. Try to follow the below steps:

Step 1: Install Dependencies

make sure latest package ^8.0.2
npm i react-native-app-auth

Add AppAuth to Podfile
Open the ios/Podfile and add:
pod 'AppAuth', '~> 1.0'

Then install the dependency:
cd ios
pod install

Reopen the project using the .xcworkspace file in Xcode.

Step 2: Configure React Native Code

Set up your OAuth configuration in JavaScript:

const authConfig = {
issuer: 'Your issuer URL',
clientId: 'your client ID',
redirectUrl: 'example://auth/', // Must match your URL scheme
scopes: ['openid', 'profile', 'email'],
serviceConfiguration: {
authorizationEndpoint: 'YOUR AUTH URL',
tokenEndpoint: 'YOUR TOKEN URL',
},
additionalParameters: {
prompt: 'select_account',
},
usePKCE: true,
useNonce: true,
prefersEphemeralSession: true,
};
const loginSSO = async () => {
try {
const result = await authorize(authConfig);
console.log('Authentication successful:', result);
} catch (error) {
console.error('Authentication error:', error);
}
};

Step 3: Register Redirect URL Scheme

Update Info.plist
In Xcode, open Info.plist and add the following inside the :

CFBundleURLTypes


CFBundleURLName
com.your.app.identifier
CFBundleURLSchemes

example

Note:
CFBundleURLName: A unique reverse-DNS identifier (e.g., com.yourcompany.appname).
CFBundleURLSchemes: The scheme part of your redirect URI (e.g., example → example://auth).

Set Up Bridging Header

Ensure RNAppAuthAuthorizationFlowManager.h is imported via a bridging header.
If you don't already have one:

1. Create a file at:
   ios/YourProject/YourProject-Bridging-Header.h
2. Add
   #import "RNAppAuthAuthorizationFlowManager.h"
   3.In Xcode, go to Build Settings → search for Objective-C Bridging Header and set it to:
   $(SRCROOT)/YourProject/YourProject-Bridging-Header.h

Modify AppDelegate.swift
Update your AppDelegate.swift to handle OAuth redirects:

import AppAuth
import UIKit
import React
import React_RCTAppDelegate
@main
class AppDelegate: RCTAppDelegate, RNAppAuthAuthorizationFlowManager {
var window: UIWindow?
public weak var authorizationFlowManagerDelegate: RNAppAuthAuthorizationFlowManagerDelegate?
override func application(
_ app: UIApplication,
open url: URL,
options: [UIApplication.OpenURLOptionsKey : Any] = [:]
) -> Bool {
if let delegate = authorizationFlowManagerDelegate,
delegate.resumeExternalUserAgentFlow(with: url) {
return true
}
return super.application(app, open: url, options: options)
}
override func application(
_ application: UIApplication,
continue userActivity: NSUserActivity,
restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void
) -> Bool {
if userActivity.activityType == NSUserActivityTypeBrowsingWeb,
let url = userActivity.webpageURL,
let delegate = authorizationFlowManagerDelegate,
delegate.resumeExternalUserAgentFlow(with: url) {
return true
}
return super.application(application, continue: userActivity, restorationHandler: restorationHandler)
}
}

Step 5: Verify the Setup

Check the Bridging Header:

1. In Xcode, navigate to Build Settings.
2. Ensure Objective-C Bridging Header is set correctly.

Clean and Build:

1. Product → Clean Build Folder
2. Product → Build

[mastene78]

it works for me with R 0.79.2

1. install latest package ^8.0.2

pod install

3. add this to Podfile:
   pod 'AppAuth', :modular_headers => true

4. swift-Bridging-Header.h should include a reference to #import "RNAppAuthAuthorizationFlowManager.h, like so:

#import "RNAppAuthAuthorizationFlowManager.h"

4. my AppDelegate.swift

import UIKit
import React
import React_RCTAppDelegate
import ReactAppDependencyProvider
import Firebase

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, RNAppAuthAuthorizationFlowManager {

var window: UIWindow?
var reactNativeDelegate: ReactNativeDelegate?
var reactNativeFactory: RCTReactNativeFactory?

// Required by the RNAppAuthAuthorizationFlowManager protocol
public weak var authorizationFlowManagerDelegate: RNAppAuthAuthorizationFlowManagerDelegate?

func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil
) -> Bool {
FirebaseApp.configure()
let delegate = ReactNativeDelegate()
let factory = RCTReactNativeFactory(delegate: delegate)
delegate.dependencyProvider = RCTAppDependencyProvider()

reactNativeDelegate = delegate
reactNativeFactory = factory

window = UIWindow(frame: UIScreen.main.bounds)

factory.startReactNative(
  withModuleName: "MayAppName",
  in: window,
  launchOptions: launchOptions
)
RNSplashScreen.show()
return true

}

// Gestion du deep linking OAuth
func application(
_ app: UIApplication,
open url: URL,
options: [UIApplication.OpenURLOptionsKey : Any] = [:]
) -> Bool {
return authorizationFlowManagerDelegate?.resumeExternalUserAgentFlow(with: url) ?? false
}
}

class ReactNativeDelegate: RCTDefaultReactNativeFactoryDelegate {
override func sourceURL(for bridge: RCTBridge) -> URL? {
self.bundleURL()
}

override func bundleURL() -> URL? {
#if DEBUG
return RCTBundleURLProvider.sharedSettings().jsBundleURL(forBundleRoot: "index")
#else
return Bundle.main.url(forResource: "main", withExtension: "jsbundle")
#endif
}
}

5. add this to info.plist :

CFBundleURLTypes


CFBundleTypeRole
Editor
CFBundleURLName
MyAppName
CFBundleURLSchemes

MyAppName

clean project xcode
run project xcode
