Implement push notifications

To implement push notifications in our app we need to create a .p8 key file from and setup the settings for the notification in the dashboard.

We also need to create a provisioning profile for the app because push notifications don't work with a wildcard provisioning profile.

In the MBurger dashboard under Settings > Info & Features you can see two fields that you will need to setup your app to receive push notifications from MBurger:

  • Push token

  • Project topic for push

The first one identifies your MBurger project and will be used to setup the service in your didFinishLaunchingWithOptions, the second one will be used to register the token of your device once you obtain one from APNS.

Add this to your AppDelegate:

import UserNotifications


func application(_ application: UIApplication,
        launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        MBManager.shared().pushToken = “YOUR_TOKEN”

        let userNotificationCenter = UNUserNotificationCenter.current()
        userNotificationCenter.delegate = self


// MARK: – Notifications

func registerForPushNotifications() {
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (granted, _) in
        guard granted else { return }

func getNotificationSettings() {
    UNUserNotificationCenter.current().getNotificationSettings { (settings) in
        guard settings.authorizationStatus == .authorized else { return }
        DispatchQueue.main.async {

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    MumblePush.registerDevice(deviceToken: deviceToken, success: {
        let topics = [“TOPIC_ID”]
        MumblePush.register(toTopics: topics)

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
    print(“Failed to register: \(error)“)

extension AppDelegate: UNUserNotificationCenterDelegate {
    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                willPresent notification: UNNotification,
        completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                didReceive response: UNNotificationResponse,
        completionHandler: @escaping () -> Void) {
