Approx Dec 13th 2025 til now (Dec 29th) I noticed my APNS dropped off to nothing daily. When I try to send APNS alerts on the developer site tool it always returns "discarded as device was offline" for multiple devices which I know are online. When I try pushing through my VPS (as I always have without any code changes for months) I get status codes of 400 and 403 mostly and a few 200's without it delivering also. I created a new sandbox certificate just in case it was that but still no luck, I get the same results. Ive checked for any firewall issues and I see the following on my VPS: nslookup gateway.push.apple.com Server: 1.1.1.1 Address: 1.1.1.1#53 ** server can't find gateway.push.apple.com: NXDOMAIN This seems like a second issue but not the primary issue that the portal is reporting. Any ideas what to check? Im at a loss as to why its not working at all through apples test notification portal on my developer account. It seems thats the initial issue I need to solve. Thank you for any ideas/help

I have been fighting this problem for two months and would love any help, advice or tips. Should I file a DTS ticket? Summary We attach a JPEG image to a local notification using UNNotificationAttachment. iOS reports the delivered notification as having attachments=1, but intermittently no image preview appears in Notification Center. In correlated cases, the attachment’s UNNotificationAttachment.url (which points into iOS’s attachment store) becomes unreadable (Data(contentsOf:) fails) even though the delivered notification still reports attachments=1. This document describes the investigation, evidence, and mitigations attempted. Product / Component UserNotifications framework UNNotificationAttachment rendering in Notification UI (Notification Center / banner / expanded preview) Environment App: OnThisDay (SwiftUI, Swift 6) Notifications: local notifications scheduled with UNCalendarNotificationTrigger(repeats: false) Attachment: JPEG generated from PhotoKit (PHImageManager.requestImage) and written to app temp directory, then passed into UNNotificationAttachment. Test contexts: Debug builds (direct Xcode install) TestFlight builds (production signing) iOS devices: multiple, reproducible with long runs and user clearing delivered notifications Expected Result Delivered notifications with UNNotificationAttachment should consistently show the image preview in Notification Center (thumbnail and expanded preview), as long as the notification reports attachments=1. If the OS reports attachments=1, the attachment’s store URL should remain valid/readable for the lifetime of the delivered notification still present in Notification Center. Actual Result Intermittently: Notification Center shows no image preview even though the app scheduled the notification with an attachment and iOS reports the delivered notification as having attachments=1. When we inspect delivered notifications via UNUserNotificationCenter.getDeliveredNotifications, the delivered notification’s request.content.attachments.first?.url exists but is unreadable (attempting Data(contentsOf:) returns nil / throws), i.e. the backing attachment-store file appears missing or inaccessible. In some scenarios the attachment-store file is readable for hours while the notification is pending, and then becomes unreadable after the notification is delivered. Reproduction Scenarios (Observed) Next-day reminders show attachment-store unreadable after delivery 1. Schedule a one-shot daily reminder for next day (07:00 local time) with UNCalendarNotificationTrigger(repeats: false) and a JPEG attachment. 2. During the prior day, periodic background refresh tasks verify the pending notification’s attachment-store URL is readable (pendingReadable=true). 3. After the reminder is delivered the next morning, the delivered snapshot shows the delivered notification’s attachment-store URL is unreadable (readable=false) and Notification Center shows no preview. Interpretation: the attachment-store blob appears to become inaccessible around/after delivery, despite being readable while pending. Evidence and Instrumentation We added non-crashing diagnostic logging (Debug builds) around: Scheduling time Logged that we successfully created a UNNotificationAttachment from a unique temp file. Logged that UNUserNotificationCenter.add(request) succeeded. Queried pendingNotificationRequests() and logged the scheduled request’s attachment url.lastPathComponent (iOS attachment-store filename). Delivered time (when app becomes active) Called UNUserNotificationCenter.getDeliveredNotifications and logged: delivered count, attachment count attachment url.lastPathComponent whether Data(contentsOf: attachment.url) succeeds (readable=true/false) Content fingerprinting Fingerprinted the exact JPEG bytes we wrote (SHA-256 prefix + byte count). Logged the iOS attachment-store filename (url.lastPathComponent) returned post-scheduling. Decode validation probe (later addition) When Data(contentsOf:) succeeds, we validate it decodes as an image using CGImageSourceCreateWithData and log: UTI (e.g. public.jpeg) pixel width/height magic header bytes What we tried / Mitigations Proactive “self-heal” for pending notifications Change: during background refresh/foreground refresh, verify the pending daily reminder’s attachment-store URL readability. If it’s unreadable, reschedule with a new attachment (same trigger). Rationale: if iOS drops the store file before delivery, recreating could repair it. Result: We observed cases where pending remained readable but delivered became unreadable after delivery, so this doesn’t address all observed failures. It is still valuable hardening. Increase scheduling frequency / reschedule closer to fire time (proposed/considered) We discussed adding a debug mode to always recreate the daily reminder during background refresh tasks (or only within N hours of fire time) to reduce the time window between attachment creation and delivery. Status: experimental; not yet confirmed to resolve the “pendingReadable=true → delivered unreadable after delivery” failure. Impact The primary UX value of the daily reminder is the preview photo; missing previews degrade core functionality. Failures are intermittent and appear dependent on OS attachment-store behavior and Notification Center actions (clearing notifications), making them difficult to mitigate fully app-side. Notes / Questions for Apple 1. Is iOS allowed to coalesce/deduplicate UNNotificationAttachment storage across notifications? If so, what is the retention model when delivered notifications are removed? 2. If a delivered notification still reports attachments=1, should its attachment-store URL remain valid/readable while the notification is still present in Notification Center? 3. In “next-day” one-shot scheduling scenarios, can the attachment-store blob be purged between scheduling and delivery (or immediately after delivery) even if the notification remains visible? 4. Is there a recommended pattern to ensure attachment previews remain stable for long-lived scheduled notifications (hours to a day), especially when using UNCalendarNotificationTrigger(repeats: false)? Minimal Code Pattern (simplified) 1. Generate JPEG (PhotoKit → UIImage → JPEG Data). 2. Write to a unique temp URL. 3. Create attachment: UNNotificationAttachment(identifier: <uuid>, url: <tempURL>, options: [UNNotificationAttachmentOptionsTypeHintKey: "public.jpeg"]) 4. Schedule notification with a calendar trigger for the next morning.

I’m using iOS 26 beta 9 on my iPhone 15 Plus. When I receive a call from a contact with multiple phone numbers, the call history does not clearly show which specific number was used to call me. Why? How to fix this issue?

Hello, I am trying to utilize the Critical Messaging API to allow my user to message 1 or multiple pre registered contacts automatically. An issue I am having with this in testing is that when the application attempts to fire off texts to the phone numbers the success rate changes from trial to trial, with no variable changing. Sometimes I can send a Critical Message to multiple phone numbers in rapid succession, sometimes the message is only sent to 1 contact, and sometimes I get no successes. Each failure always returns the MSCriticalMessaging.notSupported error. The API documentation states, "The send(_:to:) method only works if the app is backgrounded, if it’s called from foreground the framework returns a MSCriticalMessagingError.notSupported error." If my app is always backgrounded in these tests, what other issues may cause this notSupported error return, and why does the outcomes success rate vary?

If there is a Notification Service Extension which has the com.apple.developer.usernotifications.filtering entitlement, then does/how having that entitlement affect the preconditions for the NSE to be delivered a push? Specifically, if the app has not prompted for requestAuthorization() is it expected that the push will be delivered to the NSE or not? Thank you

I trying to validate the certificate I created for APNS using the following command but I get an error. openssl s_client -connect gateway.push.apple.com:2195 -cert temp.pem -debug -showcerts Error: getaddrinfo: nodename nor servname provided, or not known connect:errno=0 Any help will be greatly appreciated.

In iOS 26, I can check the notification that arrives to the user when the AirPods or Apple Watch is fully charged. When tap the notification, notification only expands and does not include actions such as moving to an app. I checked the documents of UserNotification and UNNotificationServiceExtension, but I couldn't find what I wanted. I can expand by long-tapping as default, but I'm looking for a way to expand it without entering the app when I tap the notification. I wonder if there is an API that I missed or if it's not publicly supported. thank you for your support.

Device: iPhone (real device) iOS: 17.x Permission: Granted Notifications are scheduled using UNCalendarNotificationTrigger. The function runs and prints "SCHEDULING STARTED".

We're trying to add simple notifications to our CarPlay integration that should open certain template when pressed, but the issue is that when pressing this notification on CarPlay screen nothing is invoked in the code (presumably didReceive should be invoked). All works fine with the same notification but pressed on the iPhone screen - didReceive is invoked properly. How should I handle the action when push notification is pressed on CarPlay screen?

Could anyone play a sound from the Library/Sounds directory using alarmkit? Same file can play in app bundle, but not available in Library/Sounds directory. Is this by design?

I’m building a standalone Apple Watch smart alarm app that should trigger alarms on the watch in response to Bluetooth or internet events. This means the app operates in the background and attempts to trigger an alarm when such an event occurs. As far as I know, the appropriate API for this is WKExtendedRuntimeSession.notifyUserWithHaptic:repeatHandler. However, I can’t seem to start an extended runtime session while the app is in the background. I’m getting the following error: -[WKExtendedRuntimeSession _invalidationReasonAndDelegateCallbackErrorForError:outCallbackError:]:729: WKExtendedRuntimeSession hit internal error. Error Domain=com.apple.CarouselServices.SessionErrorDomain Code=17 "startSession cannot be called on a scheduled session" UserInfo={NSLocalizedDescription=startSession cannot be called on a scheduled session} Calling notifyUserWithHaptic directly also similarly fails. It seems notifyUserWithHaptic is intended to be scheduled during a foreground session to trigger at a later time, rather than being called ad hoc from a background context. Is there any way to create a proper alarm view on the Apple Watch from a background execution context?

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?

We are observing an issue where the iOS Notification Service Extension (NSE) is terminated by the system during startup, before either didReceive(_:withContentHandler:) or serviceExtensionTimeWillExpire(_:) is invoked. When this occurs, the notification is delivered without modification (for example, an encrypted payload is shown to the user). System logs frequently contain the message “Extension will be killed because it used its runtime in starting up”. During testing, we observed that CPU-intensive operations or heavy initialization performed early in the extension lifecycle — especially inside init() or directly on the main thread in didReceive often cause the system to kill the NSE almost immediately. These terminations happen significantly earlier than the commonly observed ~30-second execution window where the OS normally invokes serviceExtensionTimeWillExpire(_:) before ending the extension. When these early terminations occur, there is no call to the expiry handler, and the process appears to be forcefully shut down. Moving the same operations to a background thread changes the behavior: the extension eventually expires around the usual 30-second window, after which the OS calls serviceExtensionTimeWillExpire(_:). We also observed that memory usage plays a role in early termination. During tests involving large memory allocations, the system consistently killed the extension once memory consumption exceeded a certain threshold (in our measurements, this occurred around 150–180 MB). Again, unlike normal time-based expiration, the system did not call the expiry handler and no crash report was produced. Since Apple’s documentation does not specify concrete CPU, memory, or startup-cost constraints for Notification Service Extensions or any other extensions beyond the general execution limit, we are seeking clarification and best-practice guidance on expected behaviors, particularly around initialization cost and the differences between startup termination. NSE Setup: class NotificationService: UNNotificationServiceExtension { static var notificationContentHandler: ((UNNotificationContent) -> Void)? static var notificationContent: UNMutableNotificationContent? static var shoudLoop = true override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) { NotificationService.notificationContentHandler = contentHandler NotificationService.notificationContent = request.content.mutableCopy() as? UNMutableNotificationContent NotificationService.notificationContent!.title = "Weekly meeting" NotificationService.notificationContent!.body = "Updated inside didReceive" // Failing scenarios } override func serviceExtensionTimeWillExpire() { NotificationService.shoudLoop = false guard let handler = NotificationService.notificationContentHandler, let content = NotificationService.notificationContent else { return } content.body = "Updated inside serviceExtensionTimeWillExpire()" handler(content) } }

Hi everyone! I’m integrating push notifications for a taxi-driver app and ran into a blocking CarPlay issue. When the iPhone is connected to CarPlay (wired or wireless), the push arrives on the phone without any sound and nothing is shown or announced on the CarPlay screen. If I unplug CarPlay, the same push plays the default sound and shows a normal banner on the lock screen, so the payload itself looks valid.

We are attempting to update our app to use the PTT framework, as it has been made clear that this will be required in a future iOS version as opposed to using the Unrestricted VoIP entitlement we are using for several features of our app. However, the behavior of this framework poses some problems with implementing our app's functionality: It is not possible to programmatically join a channel when the app is not in the foreground. This hinders our ability to implement the Automatically activate radio stream feature of our app, which allows users who have opted into this feature to immediately begin hearing live PTT audio from their agency following an incident alert. Having the app constantly "joined to a channel" and using the restoration delegate could potentially work, however this is not ideal as this would result in the PTT UI needing to be displayed at all times, even when no radio stream is activated. We have a "Text to Speech" option that, when enabled, reads out the content of an incident alert after the alert sound has played. This currently happens by triggering an AVSpeechSynthesizer in the PushKit incoming push callback. It may be possible to render TTS audio on the fly in a Notification Service Extension and assign it as the notification's sound, if that is possible this is less of a problem. We also use the PushKit callback to, again if the user has enabled it, activate a "Shake to Respond" feature, allowing a short period of time after receiving an incident alert in which the user can shake their device to indicate that they are responding to the incident. There does not appear to be any way to have the level of background execution required to implement this using an NSE, and this is of course beyond the scope of the PTT framework. What options do we have to be able to continue to provide this functionality, without risk of it being disabled in a future iOS version?
