There is one xpc server and two xpc clients (clientA and clientB). When clientB sends a message to the xpc server, xpc server fills a value for dummyString in it's memory and I want clientA to know that dummyString got updated and also the new value for this dummyString. The updation of dummyString is not something that happens often.
Two options we tried:
Have a timer for 5 seconds in clientA and keep polling and request for the value of this dummyString.
Setup a darwin notification in server that gets posted whenever dummyString is being updated. clientA receives requests for dummyString value only when it observes a notification being posted.
Which of these two approaches causes the least delay for clientA to know the updated value of dummyString?

Hi Team,
We’re following up on our request for the Critical Alert entitlement for our app, which we plan to use to notify users about critical states of their devices. It’s been almost 4 weeks since we submitted the request, and we wanted to check on the typical review timeline so we can plan our upcoming work accordingly.
If there’s anything we can provide or clarify to help complete the review or make the process easier, we’d be happy to assist. or the right forum to reach out to.

I'm working on implementing Apple Wallet passes using background push notifications.
My server successfully sends the push notification using APNs. The response from the server is HTTP/2 200, and the device receives the push — I can confirm this from device logs.
However, the device logs show the following error:
"Failed to parse JSON message payload for topic "
"Unable to deserialize JSON message payload"
My payload is below 2 payload.
//string payload = "{"aps":{"content-available":1}}";
string payload = JsonConvert.SerializeObject(new
{
aps = new Dictionary<string, object>
{
{ "content-available", 1 }
}
});
string curlArgs = $"-s -o nul -w \"%{{http_code}}\" " +
$"--data-binary \"{payload}\" " +
$"-H \"apns-topic: {bundleId}\" " +
$"-H \"apns-push-type: background\" " +
$"-H \"apns-priority: 5\" " +
$"-H \"content-type: application/json\" " +
$"-H \"authorization: bearer {jwt}\" " +
$"--http2 https://api.push.apple.com/3/device/{token}";
I’ve confirmed that:
The device has the Wallet pass installed.
The apns-topic header is set to my passTypeIdentifier.
The apns-push-type is background and apns-priority is 5.
Steps to Reproduce:
Install Wallet pass on iOS device.
Send background push to device using the above payload.
Observe the device logs using Console.app or log stream.
See error: unable to deserialize JSON message payload.
Is there a specific payload format expected for Wallet passes? Or any additional fields required in the push payload to avoid this deserialization error?
Hello. I'm currently implementing Apple Notification v2 to prepare for refunds for in-app purchases, but I'm not receiving requests from Apple servers to my backend server.
I've applied HTTPS (TLS 1.2) and correctly registered production/sandbox notification URLs on App Store Connect.
After requesting a test notification, when I check the status of testNotificationToken, I receive an UNSUCCESSFUL_HTTP_RESPONSE_CODE as follows:
{"signedPayload":"......":[{"atteptDate":1752128001970,"sendAttemptResult":"UNSUCCESSFUL_HTTP_RESPONSE_CODE"}]}
The endpoint for receiving notifications is set to accept POST requests with application/json format, and it responds with 200 (OK) without any content. However, Apple notifications are not coming through.
Could anyone help me with this issue?

This is in an iOS Simulator running iOS 18.2
I send a start live activity push notification from the Push Notifications Console on icloud.developer.apple.com. When checking the console.log output it seems to receive the message, yet the activity does not appear in the dynamic island. (the app is backgrounded when I test this)
Can anyone tell me why it's not showing? Starting the same activity from within the app using Swift code works fine.
Here is the console.app output:

Hi all,
We encountered an issue where APNs (Apple Push Notification service) push messages cannot be received during development. The specific description is as follows:
Our app runs on an iPad that connects to the cellular network using a SIM card and accesses the Internet through the company's MDM, which provides APN setting proxies.
During operation, we found that the device fails to receive push messages from APNs. Network packet capture revealed that the connection attempt by apsd to port 5223 failed. According to Apple's documentation (https://support.apple.com/zh-cn/102266), when port 5223 cannot be connected to, it will fall back to port 443 and use a proxy. However, our packet capture showed that when port 5223 was unreachable, the apsd service on the iPad did not attempt to establish a connection to port 443.
Since the iPad device currently cannot establish a connection with APNs, it consistently fails to receive push messages from APNs. We tried disconnecting the SIM card and using a Wi-Fi environment, and in this case, the iPad device was able to receive push messages from APNs normally.
Could you advise us on how to proceed with troubleshooting in this situation?

Hey there,
i implemented live activity in my app and iam trying to start the live activity from push notification, updates works fine even when the app is in background but starting the activity creating issue mostly on background and kill mode when i check the delivery of live activity on cloudkit console it says stored for device power considerations.
anyone having the same issue ?
Hi Apple Team,
we reiceved the following message.
Hello, We’re reaching out with a final reminder that the Certification Authority (CA) for Apple Push Notification service (APNs) is changing. APNs updated the server certificates in sandbox on January 21, 2025. APNs production server certificates will be updated on February 24, 2025. To continue using APNs without interruption, you’ll need to update your application’s Trust Store to include the new server certificate: SHA-2 Root: USERTrust RSA Certification Authority certificate.
Our web service sends token-based push notifications directly to the Apple Push server.
For testing: https://api.development.push.apple.com:443
In production: https://api.push.apple.com:443
We have never installed any certificates for using APNs.
Do we need to take any action regarding this message, or can we ignore it?
Hi team,
We've observed that for all background notifications (where content-available set to true, https://developer.apple.com/documentation/usernotifications/pushing-background-updates-to-your-app#Create-a-background-notification),
we never received any response with error string "Unregistered". This
differs from non-background pushes, where expired tokens are regularly
cleared.
Is this the expected behavior (i.e.,
background notifications will not return an "Unregistered" error), or could this indicate an issue on our side?
Thanks in advance for any clarification.
I am trying to retrieve delivered notifications using UNUserNotificationCenter.getDeliveredNotifications(completionHandler:), but I have encountered an issue:
Notifications triggered by UNTimeIntervalNotificationTrigger or UNCalendarNotificationTrigger appear in the delivered list.
However, notifications triggered by UNLocationNotificationTrigger do not appear in the list.
Here is the code I use to fetch delivered notifications:
UNUserNotificationCenter.current().getDeliveredNotifications { notifications in
for notification in notifications {
print("Received notification: \(notification.request.identifier)")
}
}
The notification is scheduled as follows:
let center = UNUserNotificationCenter.current()
let content = UNMutableNotificationContent()
content.title = "Test Notification"
content.body = "This is a location-based notification."
content.sound = .default
let coordinate = CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194) // Example coordinates
let region = CLCircularRegion(center: coordinate, radius: 100, identifier: "TestRegion")
region.notifyOnEntry = true
region.notifyOnExit = false
let trigger = UNLocationNotificationTrigger(region: region, repeats: false)
let request = UNNotificationRequest(identifier: "LocationTest", content: content, trigger: trigger)
center.add(request) { error in
if let error = error {
print("Error adding notification: \(error.localizedDescription)")
}
}
Why does getDeliveredNotifications not return notifications that were triggered using UNLocationNotificationTrigger?
How can I retrieve such notifications after they have been delivered?
以下の問題が発生しています:
特定のデバイスでプッシュ通知が受信されません。
考えられる原因は何でしょうか?
プッシュ通知は自社のサーバーから送信しており、APNs(Apple Push Notification service)からは正常な応答が返ってきています。
ユーザーはデバイスで通知が有効になっていることを確認しており、ネットワークの問題も報告されていません。
この問題は複数のユーザーに発生しています。
I dont want my server to be spammed. Currently I am only in payment-related notifs (eg: user successfully renewed his subscription, user didnt successfully renew his subscriptions, ..)
Where can I set that?

"As we announced in October, the Certification Authority (CA) for Apple Push Notification service (APNs) is changing. APNs will update the server certificates in sandbox on January 20, 2025, and in production on x date, 2025. To continue using APNs without interruption, you’ll need to update your application’s Trust Store to include the new server certificate: SHA-2 Root : USERTrust RSA Certification Authority certificate.
To ensure a smooth transition and avoid push notification delivery failures, please make sure that both old and new server certificates are included in the Trust Store before the cut-off date for each of your application servers that connect to sandbox and production. At this time, you don’t need to update the APNs SSL provider certificates issued to you by Apple."
As we are using firebase for receiving notifications and azure notification hub, I read that there is nothing we as developers need to do and will be handled by the providers right?
Dear Apple!
During WWDC24 you announced that ONE_TIME_CHARGE notification is available on the sandbox environment and will be available "it will be available in production later this year" - it's March 2025 and there is still no production release of this feature.
Could you share some timeline and plans for when we can expect that feature deployed to production?
Thanks in advance!
My App supports two services that is Push Notification for Alerts and a Voip Call feature whose notification also comes in the same way as of PushNotification but video rendering is done with GoogleWebRTC.
The App was working perfectly fine but from past few months these services are not working.[ Nothing is changed in App and on the server side to push the notifications]
Issues:
VoIP (Video call) not working: I have apns certificate which is valid in today's date and stays with the backend Server. My server sends the payload notification to APNS but on iPhone am unable to receive it. I have checked the App registration part also and is able to receive the token for the same.
Framework used are: PushKit, UserNotifications, GoogleWebRTC .
I don't understand where is the gap, the backend triggers the APNS but there no response.
Ports enabled on server are: 443, 5223, 2197, 2195, 2196.
Similarly Push notification were also not working, So I tried to change it to register on Firebase for device registration token And did some coding at backend to send the notification to that device. It was working perfectly fine from last few weeks, but it suddenly stopped. I checked the JSON Payload and tried to send it through PostMan, in both it says 200 Success. And in Application end am waiting for breakpoint to hit in userNotificationCenter(_: , willPresent, completionHandler).
What all I have checked:
1)My server to APNS server connectivity.
2)Verified the apns certificate. The certificate was created in October 2024, whose expiry is in Nov 2025 and it support both Sandbox and Production environment.
3)Checked required delegates are implemented in App. With the capability enable in it, is also sending registration token to backend.
Kindly guide me where I can check in this flow.
Thanks in Advance!
Hey Together,
I have seen that critical notifications need to be confirmed by apple to be used.
Sadly I couldn't figure out where to ask for that.
Context: I have a sports tournament app for Beach Handball. There are a couple of Courts like up to 20-25. The main use for that in my app would be to notify first aiders/Medics. Right now they are called in via Speakers or by the referees just writing that into a WhatsApp chat. As this takes a long time and the speakers can be deactivated due to rain, power shortage or even the medics sometimes are not in range to exactly hear the speakers calling them.
To Speed up this process I want them to download the App, Register via an E-Mail or a One Time Code. Now if a referee needs immediate Help from the Medics on their court they can send the Critical alert to the Medics without having to write a chat into a WhatsApp group, to get a call through the speakers 10 minutes later which the medics may not even hear.
A couple of weeks ago we had a player falling on her back/neck/head and they couldn't figure out if she broke her neck or not. Luckily the medics were right next to the court and saw that. but what would happen if they were a couple hundred of meters away and did not notice that? I mean the PA system was off due to a power shortage. someone trying to move her? Risking her death?
And while we are at it we could add those notifications if a team is missing to a court for a game that already should've started. Critical because it is urgent. Those notifications are handled with care.
There's plenty of articles out there about programatically grouping push notifications. However I have tried setting the thread-id in the push payload when sending a push, or setting the threadIdentifier for a received push in a notification service extension to be the same for several pushes.
But if within the iPhone Settings / Notifications the user selects to display pushes as List and turns off Notification Grouping, then each notification resulting from the push appears on its own separately.
Is there something other than thread-id/threadidentifier that is used to programmatically group them? If not then whats the point of these as grouping and display is actually under the control of user.
I'm running into an issue during the iOS build process for my app, and I'm hoping someone can point me in the right direction.
❗ The Problem
When attempting to archive the app via EAS Build (Expo), the build fails with the following error:
`Provisioning profile "HCF_AppStore_ProvisioningProfile" doesn't include the com.apple.developer.push-notifications entitlement. Profile qualification is using entitlement definitions that may be out of date. Connect to network to update.`
What I’ve Already Done:
Enabled Push Notifications capability for the App ID (com.rsmco.helpcreatefamilies) in the Apple Developer portal.
Deleted and regenerated the App Store Provisioning Profile after enabling the capability.
Confirmed the new profile is associated with the correct App ID and Distribution Certificate.
Uploaded the new profile to EAS (Expo) and rebuilt the app.
Yet the error persists during the Xcode archive step with Exit code 65.

Hey everyone!
I'm trying to develop an app that would need to send periodic notifications (every 20 minutes, for instance) to the user even when the app is not running (but only when the phone is being used). I've been reading through the prior comments and all about not being able to have a timer run in the background in the way I need it to, but I wanted to ask if there's any way around this, or is there truly no way?
If there is no way to do this, I was just now considering another workaround, where I could try getting the time they open their phone, and from there, I schedule local notification for every 20 minutes or so for the entire day, and they keep sending until the phone is turned off, when the rest of the scheduled local notifications are cancelled. Is this possible?
I would also appreciate any other suggests/workarounds for this. Happy to provide any additional details needed!
Thanks!

I am trying to issue the "start" APNs push notification to start a live activity for my iOS app. The notification appears to send correctly, there is no error message, but the live activity never appears for any of my users (users are in TestFlight).
In addition to issuing the APNs commands from my server, I have also tried using the CloudKit Push Notification Console to manually generate a "start" notification. It submits correctly but the live activity never starts.
I have also checked the Console app to watch the device logs and see if iOS is rejecting/throttling the live activity but I don't see any activity related to the start message at all.
Here are some details:
App bundle ID: `com.penzu.moodmoji`
APNs topic: `com.penzu.moodmoji.push-type.liveactivity`
APNs push type: `liveactivity`
Recent apns-id: `7b633309-b7fd-4163-b620-776efa04f315`
APNs payload:
{
"aps": {
"timestamp": 1742651625,
"event": "start",
"content-state": {
"totalDays": 7,
"currentDay": 2,
"progress": 0.29,
"status": "ACTIVE",
"reportReady": false
},
"attributes-type": "GoalActivityAttributes",
"attributes": {
"totalDays": 7,
"currentDay": 2,
"progress": 0.29,
"status": "ACTIVE",
"reportReady": false
},
"alert": {
"title": "It's day 2!",
"body": "Don't forget to record every time you feel anxious today."
}
}
}
I can confirm that LiveActivities started by the iOS app with ActivityKit work correctly, and the app does appear to be receiving pushToStartTokenUpdates:
struct GoalActivityAttributes: ActivityAttributes, Sendable {
struct ContentState: Codable & Hashable, Sendable {
let totalDays: Int
let currentDay: Int
let progress: Double
let status: String
let reportReady: Bool
}
let goal: SimpleGoal
}
for await nextStartToken in Activity<GoalActivityAttributes>.pushToStartTokenUpdates {
// send nextStartToken to server...
}
The app I'm testing with is in TestFlight, using the production APNs environment.
