register Callback in PushNotifications Plugin Fails to Trigger Registration or Error Listeners

[Grifting]

Plugin(s)

@capacitor/push-notifications: ^6.0.2

Capacitor Version

@capacitor/cli: ^6.1.2
@capacitor/core: ^6.1.2
@capacitor/ios: ^6.1.2
@capacitor/push-notifications: ^6.0.2

Platform(s)

iOS only

Current Behavior

When calling PushNotifications.register() on an iOS device, neither the registration nor registrationError listeners are triggered. No token or error feedback is returned, despite APNs being configured in the Apple Developer Portal, necessary permissions enabled in Xcode, and no apparent errors in the console log.

Expected Behavior

After invoking PushNotifications.register(), we expect either the registration listener to provide the device token or the registrationError listener to handle errors, allowing us to proceed with or debug APNs registration.

Code Reproduction

The following setup was used to reproduce the issue.

AppDelegate.swift:
import UIKit
import Capacitor

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
// default functions

// Added the functions to handle APNs registration callbacks  
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {  
    return true  
}  

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {  
    NotificationCenter.default.post(name: .capacitorDidRegisterForRemoteNotifications, object: deviceToken)  
}  

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {  
    NotificationCenter.default.post(name: .capacitorDidFailToRegisterForRemoteNotifications, object: error)  
}  

}

PushNotificationService.ts:
import { Capacitor } from “@capacitor/core”;
import { PushNotifications } from “@capacitor/push-notifications”;
import axios from “axios”;

class PushNotificationService {
private client = axios;
private apiRoot = ‘/apns’;

public async setup() {  
    await this.setupListeners();  

    if (Capacitor.getPlatform() !== 'ios') return;  

    const result = await PushNotifications.requestPermissions();  
    console.log("RESULTS: ", result)
    if (result.receive === 'granted') {  
        await PushNotifications.register();  
    }  
}  

private async setupListeners() {  
    await PushNotifications.addListener('registration', (token) => {  
        console.log('Token registered', token.value);  
        this.sendTokenToBackend(token.value);  
    });  

    await PushNotifications.addListener('registrationError', (error) => {  
        console.log('Registration error:', error);  
    });  

    await PushNotifications.addListener('pushNotificationReceived', (notification) => {  
        console.log('Push notification received:', notification);  
    });  

    await PushNotifications.addListener('pushNotificationActionPerformed', (notification) => {  
        console.log('Push notification action performed:', notification);  
    });  
}  

private async sendTokenToBackend(token: string) {  
    try {  
        await this.client.post(`${this.apiRoot}/token`, { token });  
    } catch (error) {  
        console.error('Error sending token:', error);  
    }  
}  

}

export default new PushNotificationService();

Other Technical Details

•	Device: iPhone 14 Pro Max
•	iOS Version: 18.1
•	Xcode Version: 16.1

Additional Context

Testing has been conducted over USB with Xcode’s console. APNs and Push capabilities are active, and necessary permissions granted. No errors appear in the logs, but we have not observed any registration response.
