If an iOS application has a notification service extension which gets sent a push, but the user has not been prompted for notification authorization via requestAuthorization() then what is the expected behavior?
Will the push get delivered to the NSE but the resulting notification not displayed? Or will the push not get delivered at all to the NSE?

Hello,
I am developing an application using VoIP Push and CallKit. I have a question: Starting with iOS 13, I understand that under the VoIP Push policy, if reportNewIncomingCall is not called continuously, the VoIP Push may be blocked. Is there a way to determine if the device has been blocked?
I am curious whether PKPushRegistry itself is unable to receive pushes or if reportNewIncomingCall returns an error when it is blocked. If push notifications are not being received, what should I do to resume receiving them?
Thank you.
Hello everyone,
I’m working with AlarmKit (iOS/iPadOS 26) and encountering a critical blocker. On the simulator, after adding NSAlarmKitUsageDescription to Info.plist, AlarmKit functions as expected—no entitlement issues. However, when building to a physical device, Xcode fails with:
“Provisioning profile … doesn’t include the com.apple.developer.alarmkit entitlement.”
The core issue: there is no AlarmKit capability visible under App ID settings or provisioning profiles in the Developer Portal. Thus, this entitlement cannot be enabled or included in a profile.
Steps taken so far:
Reviewed WWDC25 AlarmKit session and documentation.
Reviewed Apple Developer documentation on entitlements and provisioning.
Verified there's no AlarmKit toggle or capability in the Developer Portal (Certificates, Identifiers & Profiles > Identifiers).
Submitted multiple Feedback requests via Feedback Assistant, but received no technical resolution.
Questions:
Is there meant to be a separate AlarmKit entitlement (distinct from Critical Alerts)?
If so, when will the com.apple.developer.alarmkit entitlement option be available in the Developer Portal?
In the meantime, how can developers test AlarmKit-based features on physical devices?
Could an Apple Engineer advise on whether an internal entitlement workflow or workaround exists for testing?
Thank you in advance for any clarity anyone can provide. I'm stuck at a total impasse until this is resolved.

Hello. Recently, the users of our APP have reported using our products, and they can normally receive push in Hong Kong. However, when traveling to Japan or some countries and regions in Europe, push will not be received.
we checked that
-the cert is valid
-the server get 'sent successfully' response
-used pushtry to test the cert and token and it can receive push in app
Hi there,
Thank you for the framework 🙏
if I use Alarm.Schedule.Relative with Alarm.Schedule.Relative.Time(hour: hour, minute: minute) and Alarm.Schedule.Relative.Recurrence.never it seems like there is some (odd?) limit where alarm will get scheduled to next day if too close?
For example, lets say the current time is 12:00 PM, if I schedule alarm for 12:02 PM, it will schedule it for next day, while if I do 12:05 PM it will work as expected.
Is that expected? If yes, what's the behavior and is that documented anywhere?
I would expect any alarm thats scheduled in the future to fire for the current day (maybe if it's only 1 minute it gets tricky).
One problem is also that even if the framework says an alarm is scheduled, I don't have access to the "next alarm date"? I wish I did as otherwise I have to compute it (by "guessing" the AlarmKit calculation) if I want to do anything with that date.
Honestly, sometimes I think I am just going crazy when the alarm doesn't fire, but there SEEMS to be some odd behavior around this?
(of course, feel free to correct me on anything - I could be missing documentation or not understanding something)

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.
Hi, am facing an issue related to voip push notifications getting delivered 1-2 hours after apns-expiration to 0 and apns-priority to 10.
I had raised a similar post got a reply that it may be due to network delay.
But network delay can cause the delivery of voip push to be delayed only by few seconds or minutes. But in our case voip push is getting delivered hours after the voip call was attempted.
Steps to reproduce:
Put our voip app in background and lock iPhone. As app is put in background, socket connections gets disconnected from server.
Now if a caller makes call to this app, the call should be delivered through voip push.
2) Voip push should ideally be received even if app is in background and iPhone is locked. It is connected to a good wifi network. But it does not receive the voip push.
3) After 1-2 hours user unlocks iPhone and opens voip app. As soon as user opens app, the voip push is received and phone starts ringing.
Hello,
I have the new root certificate is installed on the server (regarding "Action Required: Apple Push Notification Service Server Certificate Update"). I have switched to using sandbox environment to test if it would be working but I get error:
"reason":"BadCertificateEnvironment"
does it mean that the root certificate is not installed correctly or that is a different issue?
What could be the reason for that?
I have found that this response corresponds to "The client certificate is forthe wrong environment.", but there weren't an option to set environment on "https://identity.apple.com/pushcert/".
I am unable to connect to APNs sandbox push endpoint from our backend servers. It works fine when hitting the request from my local machine but it fails from the infra servers. Here are the complete curl details.
Endpoint: https://api.sandbox.push.apple.com:443

When User restarted iOS device, after powering on iOS App is not able to get VoIP push notification. If user opens App, immediate VoIP push receiving.
In Normal (App Kill or Background state) everything works as expected. Issue is when device is powered on and immediately( In 1-2 mins) try to call on device.
We are using delegate to show Call to User
public func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion: @escaping () -> Void)
When the app kills the process. Received APNs push message. Push messages carry voice related information. At the same time as receiving the push, obtain the voice playback of this voice message. How to achieve it?
Hi!
I am encountering an issue when attempting to send a test notification to update a live activity. The request is failing with the following error:
{
"code": 400,
"message": "bad-request",
"reason": "The device token doesn't match the specified topic.",
"requestUuid": "3ed3fc0c-9c57-4d67-8ae8-cbabe0579b10"
}
I have verified that all device tokens and app identifiers are correct, but the error persists. Could you please assist in identifying the root cause of this issue?
We have an application which keeps throwing the error "application is damaged and cannot be opened. You should move it to Trash"
We have checked the following possible root causes:
Codesign of the application using the codesign command
Notarization of the application using the spctl command
Executable permissions
Checked for the presence of "com.apple.quarantine" flag for the application using xattr -l <path to executables"
None of the above listed items seemed to be a problem and are as expected.
Can you please help us understand what could cause this issue and how to resolve this without recommending an uninstall/reinstall of the application?
I am sending push notifications on iOS, and I can receive and display them correctly. I want to be able to dismiss notifications that have been read server-side (e.g. on a different device) so I am trying to send a custom notification payload alongside a badge counter update, that specifies what notification IDs to remove. I then use removeDeliveredNotifications on the IDs I get. However, it doesn't seem to be working. I am setting the identifier using the apns-collapse-id header and I do see that reflected on the device side. Any ideas what I might be doing wrong?
This is how I'm handling push notifications:
func userNotificationCenter(
_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void
) {
let customPayload = notification.request.content.userInfo
if let dismissedNotifications = customPayload["dismissed_notifications"] as? [String] {
center.removeDeliveredNotifications(withIdentifiers: dismissedNotifications)
}
completionHandler([.banner, .sound, .badge])
}
I also tried doing the same thing inside
func userNotificationCenter(
_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: @escaping () -> Void
)
Thank you!
I am sending push notifications to the app with critical alerts, but there is a significant delay.
If the number of target devices is 1000 or less, notifications will be received normally within a few seconds to a minute.
Once the number of target devices exceeds 1000, some devices will arrive quickly (normally within a few seconds to 1 minute) and others will arrive late (3 minutes to 15 minutes, divided into hundreds of items).
In severe cases, notifications to more than 80% of devices will be delayed.
Example: If you send 3000 notifications at once,
1 minute: Notify 400 items
5 minutes: Notify 1000 items
10 minutes: Notify 1000 items
13 minutes: Notify 600 items
*The timing of 5 minutes, 10 minutes, and 13 minutes changes every time and is not at regular intervals.
We understand that according to the push notification specifications, sending several thousand messages at once is not a problem.
Please let me know if there is a rule, such as sending 1000 items at a time, in order to deliver quickly and with minimal delay.
Hello, I'm from Microsoft team maintaining push notification api behind Teams platform.
We are experiencing strange and short error spikes towards APNS that seem to mostly correlate worldwide. We checked the networking and push request code but could not find what could be causing this. These error spikes are all timeouts or connection resets (by remote host, ie. APNS servers) and seem to come and go randomly:
Would it be possible to check this for outages or some other metrics on your side or investigate why would it happen? Since it's worldwide it seems unlikely it's something broken on our side. We are using the standard APNS http2 endpoint with modern support for all RFC features (so everything should work normally).
Mind you, our api might be in a unique position because of the volume of notifications (in the billions per day).
When I use https://api.push.apple.com/3/device/e0ae826f3905b010e37c4a07e873481b8446c9dc2788511b2995992884468068

why?
I'm having trouble displaying the Apple Wallet pass logo on iOS 18 when a notification occurs. It works on iOS 17 but not on iOS 18 (tested on versions 18.1 and 18.3).
I ensured the Wallet pass icon sizes are correct:
icon.png → 29×29
icon@ 2x.png → 58×58
icon@ 3x.png → 87×87
Questions:
Has Apple changed any requirements for displaying Wallet pass logos in iOS 18?
Are there new size, format, or metadata constraints?
Is there a way to configure the APNS notification sound volume to be louder?
I am implementing some custom sounds(narrative sentences) for APNS, it does play the custom sound, but the volume of the custom sound is not loud enough even though I had set the device's volume and "RingTone and Alerts" volume to max.
I tried to amplify the custom sound file, it does play louder but the result is minimum if I want to maintain the quality of the sound without it been distorted.
I tried to use Notification Service Extension, AVAudioPlayer and AVAudioSession to play the sound, it does play louder in max volume compare with relying on default sound payload in APNS, but the problem is AVAudioPlayer and AVAudioSession do not seems to be usable when the application is in background or killed state, is there any other alternative I could use?
I received an email from Apple saying that I needed to replace the APNS certificate.
I am inquiring because I am curious about who has the relevant authority and who actually makes the changes.
Could you please provide specific guidance on this?
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.
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.
If you have any questions, please contact us.
