Is there any callback available when a/all notifications is/are removed from notification tray?
I create a notification with an image attachment:
let center = UNUserNotificationCenter.current()
center.delegate = self
let content = UNMutableNotificationContent()
// some more stuff…
let paths = NSSearchPathForDirectoriesInDomains(
FileManager.SearchPathDirectory.documentDirectory,
FileManager.SearchPathDomainMask.userDomainMask, true)
let documentsDirectory = paths[0] as NSString
let fileExtPNG = "#" + "\(imageName)" + " photo.png"
let fileNamePNG = documentsDirectory.appendingPathComponent(fileExtPNG) as String
url = URL(fileURLWithPath: fileNamePNG)
let attachment = try UNNotificationAttachment(identifier: "Image", url: url, options: nil)
content.attachments = [attachment]
I then add the request:
let request = UNNotificationRequest(identifier:requestIdentifier, content: content, trigger: nil)
center.removePendingNotificationRequests(withIdentifiers: [requestIdentifier])
center.add(request) {(error) in }
Problem: when I later test (once notification has been registered), the file do not exist anymore at the url.
I've commented out the add request to confirm.
I have a work around, by creating a temporary copy of the file at the URL and pass it in the attachment.
Then, everything works fine and the copy is deleted.
But that's a bit bizarre. What am I missing here ?
Hi, With the upcoming changes to the Apple Push Notification service (APNs) server certificates — including the SHA-2 Root: USERTrust RSA Certification Authority certificate update — I wanted to clarify if we need to take any action with Salesforce.
Our team also received this email regarding the APNS. I don't know if I need to do something or not, since I haven't found any information in SAP Forums either.
Our app uses the SAP Mobile Services push notifications.
If any of you know any information about this, please let me know.
I've built an iOS & Watch OS app using Sign in with Apple & CloudKit exclusively.
I'm now wanting to implement Push Notifications. I understand that I need a server to trigger the push notifications (I guess I could spool up a Node server somewhere or use Firebase), but I'd really like to not use any non-Apple backend services.
Am I correct in understanding that I can do this with Push Notifications Console, or do I still need a separate backend?
Hi, I’m having issues with push notifications on my phone across multiple apps. When someone sends me a message, I only receive the notification 10 to 15 minutes later. For example, on WhatsApp, people say that my chat only shows one checkmark when they send me a message.
I don’t know what else to do. I’ve already contacted Apple Support, visited an Apple-affiliated physical store, and followed all the recommended procedures. This is my first time using an iPhone—I bought it for professional use, but it’s practically useless if I don’t receive notifications instantly.
They even told me that if I send it in for warranty service, there’s a 90% chance they won’t detect the issue, and the iPhone will come back with the same problem.
Hello,
I have been implementing NEAppPushProvider class to establish my own protocol to directly communicate with our provider server without the need to rely on APNs for background push notifications.
I am at a stage where I am able to establish a tcp communicator and receive messages back and forth but I noticed that when I disconnect from the WIFI I've set up by setting a given SSID, I am not getting hit on the Stop method. Below is briefly how I load and save preferences.
NEAppPushManager appPushManager = new NEAppPushManager();
appPushManager.LoadFromPreferences((error) =>
{
if (error != null)
{
Console.WriteLine($"Error loading NEAppPushManager preferences: {error.LocalizedDescription}");
return;
}
if (!enable)
{
Console.WriteLine("Disabling Local Push Provider...");
appPushManager.Enabled = false;
// ✅ Immediately update UserDefaults before saving preferences
userDefaults.SetBool(false, Constants.IsLocalPushEnabled);
userDefaults.Synchronize();
appPushManager.SaveToPreferences((saveError) =>
{
if (saveError != null)
{
Console.WriteLine($"Error disabling Local Push: {saveError.LocalizedDescription}");
}
else
{
Console.WriteLine("Local Push successfully disabled.");
}
});
return;
}
// ✅ Now we can safely enable Local Push
Console.WriteLine($"Enabling Local Push for SSID: {_currentSSID}");
appPushManager.MatchSsids = new string[] { _currentSSID };
appPushManager.LocalizedDescription = "LocalPushProvider";
appPushManager.ProviderBundleIdentifier = Constants.LocalPushExtensionBundleId;
appPushManager.Enabled = true;
appPushManager.SaveToPreferences((saveError) =>
{
if (saveError != null)
{
Console.WriteLine($"Error saving Local Push settings: {saveError.LocalizedDescription}");
}
else
{
Console.WriteLine("✅ Local Push successfully registered.");
userDefaults.SetBool(true, Constants.IsLocalPushEnabled);
userDefaults.Synchronize();
}
});
});
I've read through documentation and was expecting the Stop method to be hit when I turn off Wifi. Am I missing anything? Please let me know if I should provide more info. Currently I just have a console writeline method inside the Stop method to see if it actually gets hit.
Hi,
Regarding the announcement about the Apple Push Notification Service (APNs) Server Certificate Update, I wanted to clarify whether it will impact my app’s push notification setup.
I use Firebase Cloud Messaging (FCM) to send push notifications to iOS devices, and in my Firebase project settings, I have configured an APNs Authentication Key under the Apple app configuration tab (Firebase Console > Project Settings > Cloud Messaging > iOS app configuration).
The authentication key I am using was generated from Apple Developer > Certificates, Identifiers & Profiles > Keys.
Since I am using this authentication method instead of APNs certificates, are there any changes I need to be aware of due to the APNs server certificate update, and do I need to update anything in my current configuration to ensure push notifications continue to work?
Thanks in advance!

Hello Everyone,
I have some questions regarding the Apple notification alert update received in October 2024 for the APNs server certificate update.
We are using Azure Notification Hub to receive push notifications. I confirmed with the Azure team, and they have already implemented the required changes. However, push notifications are still not working in the sandbox environment.
Could you please provide any insights on this?
Thanks.
Hello Everyone,
We have some doubts regarding the apple notification alert update received in Oct 2024 for APNS server certificate update.
Does this change is already live for sandbox environment?
As we have checked on sandbox environment without changing any certificate its working and we are able to get push notification.
Does that means our system does not need any change for production as well?
If required where we should add https://www.sectigo.com/knowledge-base/detail/Sectigo-Intermediate-Certificates/kA01N000000rfBO. This certificate.
For FYI we are using python library called django-push-notifications which internally call to the APNS server for push notifications.
Do we need this new certificate "SHA-2 Root : USERTrust RSA Certification Authority certificate" if we are using token based authentication with APNs? We are signing the JWT with the private Auth key?
Or is the new certificate needed on top of this?
We are doing something like this:
Dictionary<string, object> payload = new Dictionary<string, object>()
{
{ "iss", teamId }, // Apple Developer Team ID
{ "iat", unixTimestamp } // Issued-at time
};
Dictionary<string, object> header = new Dictionary<string, object>()
{
{ "alg", "ES256" },
{ "kid", keyId } // Key ID from Apple Developer portal
};
string token = JWT.Encode(payload, privateKey, JwsAlgorithm.ES256, header);
Hey all!
During the migration of a production app to swift 6, I've encountered a problem: when hitting the UNUserNotificationCenter.current().requestAuthorization the app crashes.
If I switch back to Language Version 5 the app works as expected.
The offending code is defined here
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
FirebaseConfiguration.shared.setLoggerLevel(.min)
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(options: authOptions) { _, _ in }
application.registerForRemoteNotifications()
Messaging.messaging().delegate = self
return true
}
}
The error is depicted here:
I have no idea how to fix this.
Any help will be really appreciated
thanks in advance

Hello ,
We are trying MDM APNs push using following command
curl.exe -X POST --http2 -k -v --cert PushCert.pem --cacert cacert.pem https://api.push.apple.com/3/device/9BFDFB46D48159D16E5DC80391B765EE99524CF294BB4BF9FB5AEA7A5F3FFD79 -d "{"mdm":"84F0C145-5963-4F06-9D11-DFBDB45802D5"}" -H "apns-topic: com.apple.mgmt.External.c217c1bf-ad51-42a9-9108-2e92ef705b2a" -H "apns-push-type: mdm"
The command process correctly there is no error but device doesn't receive the Apns push.
At the same time the older device recives the Apns push but newer device not.
What can be the cause,how to debug this issue.
Hi,
I'm working on an IOS app using capacitor. I'm trying to receive push notifications on my downloaded app from testflight. I tried with FCM and it's working on my android app but not on ios and the logs show no error.
This is how I retreive the FCM token:
const fcmToken = await FCM.getToken()
sendSubscriptionToBackEnd({
fcm_token: fcmToken.token,
device: platform
})
Then I have a job on my backend to send the push notifications:
def perform
fcm = FCM.new(
StringIO.new(Rails.application.credentials.google_application_credentials),
Rails.application.credentials.firebase_project_id
)
NotificationSubscription.find_each(batch_size: 100) do |subscription|
begin
response = fcm.send_v1({
token: subscription.fcm_token,
notification: {
title: 'Un nouveau signal a été publié',
body: 'Un nouveau signal a été publié, cliquez ici pour le voir'
},
android: {
priority: 'high'
},
apns: {
payload: {
aps: {
# alert: {
# title: 'Un nouveau signal a été publié',
# body: 'Un nouveau signal a été publié, cliquez ici pour le voir'
# },
sound: 'default'
}
},
headers: {
"apns-priority": "10",
"apns-push-type": "alert"
}
}
})
if response[:status_code] == 200
Rails.logger.info "Notification sent successfully to #{subscription.id} on device #{subscription.device}"
else
Rails.logger.error "Failed to send notification to #{subscription.id} body: #{response[:body]}"
# subscription.destroy
end
rescue StandardError => e
Rails.logger.error "Error while sending notification to #{subscription.device}: #{e.message}"
subscription.destroy
end
end
end
and the logs show that it's successful but i dont receive the notification. When I test from firebase console I receive the push notification on both ios and android capacitor apps. I also added this in the apple delegate:
Messaging.messaging().apnsToken = deviceToken
Messaging.messaging().token(completion: { (token, error) in
if let error = error {
NotificationCenter.default.post(name: .capacitorDidFailToRegisterForRemoteNotifications, object: error)
} else if let token = token {
NotificationCenter.default.post(name: .capacitorDidRegisterForRemoteNotifications, object: token)
}
})
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
NotificationCenter.default.post(name: .capacitorDidFailToRegisterForRemoteNotifications, object: error)
}
I also tried using apns tokens and ther apnotic gem:
console.log('APNs Token:', token.value)
if (platform === 'ios') {
sendSubscriptionToBackEnd({
apns_token: token.value,
device: platform
}).then(() => {
displaySnackbar(`APNs token: ${token.value}`, 'success')
})
}
})
# Create the APNs connection outside the loop
connection = Apnotic::Connection.new(
auth_method: :token,
cert_path: StringIO.new(Rails.application.credentials.apns_key_path),
key_id: Rails.application.credentials.apn_key_id,
team_id: Rails.application.credentials.apple_team_id
)
NotificationSubscription.find_each(batch_size: 100) do |subscription|
if subscription.device == 'ios'
begin
# Create the notification for the current device token
notification = Apnotic::Notification.new(subscription.apns_token)
notification.alert = "Un nouveau signal a été publié"
notification.topic = Rails.application.credentials.apple_bundle_id
# Prepare and send the push
push = connection.prepare_push(notification)
push.on(:response) do |response|
if response.ok?
Rails.logger.info "Notification sent successfully to #{subscription.id} on device #{subscription.device}"
else
Rails.logger.error "Failed to send notification to #{subscription.id} body: #{response.status} - #{response.body}"
end
end
connection.push_async(push)
rescue StandardError => e
Rails.logger.error "Error while sending notification to #{subscription.device}: #{e.message}"
subscription.destroy
end
end
end
connection.join(timeout: 5)
connection.close
end
but i have a bad token error:
Failed to send notification to 223 body: 400 - {"reason"=>"BadDeviceToken"}
I, [2025-01-23T02:23:59.013407 #104] INFO -- : [ActiveJob] [ApnsNotificationJob]
I checked my aps entitlement env and its production, have all the certificates, keys.. so I dont understand why i can receive push notifications from firebase console but not from my app
I'm having an issue on my standalone watchOS app where the settings to adjust notifications does not appear anywhere on the iPhone or the Watch. I have successfully requested notifications access from the user and have successfully displayed a local notification to them. However, if the user ever decides to revoke my notification access (or if they deny originally and want to change), the settings pane for notifications does not appear anywhere.
I've looked in the following places:
On the watch in Settings > Notifications, however it looks like you can no longer edit per app notification settings directly on the watch (none of the installed apps on my watch appear in here). The only options are settings like "tap to show full notification" and "announce notifications" which affect all notifications (Why not? Especially for apps that don't have a iPhone companion app?).
On the iPhone in the Watch app (the app you set up your watch in), in Watch > Notification. My app does not appear anywhere in there.
On the iPhone in the iPhone Settings app, in Settings > Notifications. My app does not appear anywhere in there.
On the iPhone in the iPhone Settings app, in Settings > Apps. My app does not appear anywhere in there
I've tried:
Adding capabilities in Signing & Capabilities for Push Notification, Time-Sensitive Notifications and Communication Notifications
Building the app for release instead of debug
My app also requires location access and has successfully appeared in the settings pane directly on the watch in Settings > Privacy & Security > Location Services, however notification settings do not appear anywhere.
I have created a stripped down test app to try and that also does not work. This test code successfully asks the user for permission and (from a button in ContentView), successfully schedules a notification and displays it to the user when they're not in the app. Here's the code for my NotificationManager:
import UserNotifications
class NotificationManager: NSObject, ObservableObject, UNUserNotificationCenterDelegate {
static let shared = NotificationManager()
@Published var hasAuthorisation = false
private override init() {
super.init()
UNUserNotificationCenter.current().delegate = self
requestAuthorisation()
}
func requestAuthorisation() {
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound]) { authorised, error in
DispatchQueue.main.async {
if let error = error {
print("Error requesting notifications: \(error.localizedDescription)")
}
self.hasAuthorisation = authorised
}
}
}
func scheduleNotification(title: String, body: String, timeInterval: TimeInterval) {
let content = UNMutableNotificationContent()
content.title = title
content.body = body
content.sound = .default
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: timeInterval, repeats: false)
let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
UNUserNotificationCenter.current().add(request) { error in
if let error = error {
print("Error scheduling notification: \(error.localizedDescription)")
} else {
print("Notification scheduled successfully.")
}
}
}
}
This issue has persisted across two iPhones (recently upgraded) and the watch was wiped when connecting to the new iPhone.
Am I missing some code? Am I missing some flag I need to set in my project somewhere? Please can someone with an Apple Watch try this code in a standalone watchOS app and see if the notifications pane appears anywhere for them? I've contacted Apple DTS, but they're taking a while to respond.
Hello,
I am building a swift macOS app and have noticed issues today with delivering APN's to both development and production devices. Similar to this thread the only way I can get them to deliver temporarily is to do one of:
Change the bundle ID of my app to a new bundle ID, then start it up. I will usually get the first notification.
Reset my network (either wired ethernet or wifi, typically both)
Using the push notifications console for development sends, I see the message "discarded as device was offline" in the delivery log even though the device is still online and was just registered when I got back the deviceToken.
If I set an expiration on development notifications then the delivery log says "stored for device power considerations" and the notification will then send once I do one of the above steps (new bundle or reset network).
Previous to today the notifications were sending immediately and I had no issues getting them. Is there something I can do to fix this problem, is it a problem with the APN provider, or is it something else I haven't thought of?
A unique ID for an expiration-based notification is 1755def8-1a44-cbcf-c64b-64e435c30f81, and a non-expiry is d7a72b46-0c64-4500-0abc-3734f9efbd90.
I tried below at 2:00 PM on 21/01/2025(JST).
Apple Push Notification service server certificate update
I followed above,
a new server certificate: "SHA-2 Root : USERTrust RSA Certification Authority certificate" was added to my push server, but a certificate error occurred and push notifications could not be sent.
So I refered this article,Instead of connecting via DNS name resolution at api.development.push.apple.com,
I fixed api.development.push.apple.com to "17.188.143.34" in /etc/hosts,
I could push notifications with the new server certificate.
(I got this IP(17.188.143.34) from this airtcle)
From this, I suspect that Apple had not yet updated the APNs certificate (CA) for the Sandbox environment as of 2:00 PM on January 21, 2025 (JST).
Was the update published as scheduled?

Problem
We have successfully set up push notifications using Apple APN service, that is push notifications work when using a token generated using the JSON Web Token Generator in the Push Notification console. However, we get an "InvalidProviderToken" error when creating using our own token using the following code.
The Key and TeamID is definitely correct (obviously, censored in the below code). When pasting our token in the JSON Web Token Validator in the Push Notification console we get the error „Invalid signing key“. We merely pasted our secret key in our setNewTokenIfNeeded code, separated on four lines using the “““ style.
Does anyone know why this error happens? Given that it works when we upload our .p8 file to the JSON Web Token Generator and we simply paste the text of this file (excluding the lines with "-----BEGIN/END PRIVATE KEY-----") I guess our secret key is correct?

On a similar note, some people seem to encounter this error when using the prettyPrinted option for the JSON serialization (i.e., in request.httpBody = try! JSONSerialization.data(withJSONObject: payload, options: .prettyPrinted). Could this be the culprit, given our secret key contains „/„ and „+“?
Many thanks!
