Can an e-commerce app qualify for the com.apple.developer.usernotifications.filtering entitlement, or what is the alternative?
I am working on a large-scale e-commerce application and we are trying to solve a specific issue regarding push notifications and user experience. We have a use case where we need to send a standard push notification to the user, but under certain local conditions on the device, we want to intercept that notification via a Notification Service Extension and suppress/drop it so it does not alert the user. We understand that the com.apple.developer.usernotifications.filtering entitlement allows a Notification Service Extension to drop notifications. However, looking at the entitlement request form, the categories seem strictly limited to: End-to-end encrypted messaging Earthquake warnings Education/learning platforms Enterprise healthcare apps My questions for the community and Apple staff: Is it possible for an e-commerce or retail app to be approved for this entitlement if we have a highly specific, valid use case that improves user experience. If this entitlement is strictly off-limits for our domain, what is the Apple-recommended architecture to achieve this? Thank you in advance for any insights or guidance!

Can I enable push notifications in an iOS app built from a web app URL using PWA Builder?
Hi all, I have a React web app that we use as a Progressive Web App (PWA). We currently: Use PWA Builder to package it for Android and iOS Host the app on a secure HTTPS URL Use Firebase Cloud Messaging (FCM) for push notifications (working on Android) However, on iOS, we are unable to get push notifications to work. I understand that PWAs on iOS have limited push support (Safari only, and not through WebView). So I explored using Capacitor, but: Capacitor can load a server.url pointing to our hosted app (great for reuse), but push notifications don’t work If we build the web app locally (npm run build) and embed it in the native iOS shell via Capacitor, push works We would prefer not to fully merge our authentication and main app UIs if avoidable Questions: Is there any approved way to enable push notifications in an iOS .ipa built from a hosted web app (URL) using PWA Builder? If not, is embedding the web assets locally the only Apple-approved way to get push support? Are there any best practices or native plugin recommendations (e.g., APNs or FCM) for handling push notifications in iOS app? Thanks in advance for any guidance. 🙏 Let me know if more technical details would help.

APNs Notifications Always Failing – 0-Byte Response
Hello, We are currently facing a persistent issue where Apple Push Notifications (APNs) are no longer being delivered to devices. This is not an intermittent problem — push notifications have completely stopped working. We are using PushSharp.Apple (Version 4.0.10.0) to send the notifications. Current Behavior (Failing): Every notification request appears to be processed successfully from the server side. However, the APNs client receives a 0-byte response, and the server closes the connection. Devices do not receive the notifications at all. Logs from Current (Failing) State: APNS-Client[1]: Connected (Batch ID=1) APNS-Client[1]: Sent Batch, waiting for possible response... APNS-Client[1]: Received 0 bytes response... APNS-Client[1]: Server Closed Connection... APNS-Client[1]: Disconnected (Batch ID=1) For Reference – Successful Log From Earlier (When Notifications Worked): APNS-Client[1]: Connected (Batch ID=1) APNS-Client[1]: Sent Batch, waiting for possible response... APNS-Client[1]: Received -1 bytes response... Push Notification Successfully Sent to Device Any help, suggestions, or experience with similar issues would be greatly appreciated. Thanks!!!

Notification easy control
Dear Apple Team, I hope this message finds you well. I wanted to share a playful and innovative idea that could enhance the iPhone experience—particularly when viewing content in full-screen mode through apps like Apple TV or YouTube. Feature Concept: Hands-Free Dismissal of Notifications When the iPhone is in landscape mode, incoming notifications can interrupt the viewing experience. While Focus Mode and swipe gestures help, I thought of a more intuitive and hands-free interaction: using a light puff of air directed toward the screen to dismiss a notification. This interaction could use the microphone or other onboard sensors to detect a brief burst of air, providing a fun and natural way to maintain immersion without touching the device. If this isn’t feasible with current hardware, here are a few alternative concepts that align with the same goal: Blink to Dismiss: Using Face ID sensors to detect a quick blink as a hands-free gesture. Shake to Dismiss: A gentle shake gesture when holding the iPhone in one hand. Gaze-Based Dismissal: Notifications automatically disappear after a brief moment of eye contact. These ideas could offer both accessibility benefits and a touch of delight—making the iPhone feel even more magical and responsive. Thank you for your time and for considering this suggestion! Warm regards, Badhan Baidya

Why are non-critical notifications quieter than critical alerts at max volume?
When I turn the Ringtone and Alerts volume all the way up, I expect standard notifications to play at the loudest level the device allows. In theory, this should match the volume of a critical alert with its sound.volume set to 1.0 in payload. However, I’ve noticed that non-critical notifications still play quieter than critical alerts under these conditions. Critical alerts with volume: 1.0 sound noticeably louder than standard notifications, even though the Ringtone and Alerts slider is already set to maximum. And I couldn't find a documentation for this behavior anywhere. Is this expected behavior on iOS? And is there any way to make non-critical notifications play at the same maximum loudness as critical alerts? Thanks in advance for any clarification.

Issue with app not waking up intermittently due to Pushkit (VOIP)
I am developing a VoIP service. Usually, when receiving a VoIP Push, Callkit is exposed immediately after receiving the message and the app is designed to be used. However, there is an extremely intermittent phenomenon (not well reproduced) where the app does not wake up even when receiving a VoIP Push. And after a long time, the app wakes up and Callkit is activated. (A long time after receiving the call…) Has anyone experienced the above phenomenon? I wonder if there are any reported parts depending on the OS version. (I have identified that it does not occur in the 17.x version, but it is difficult to guarantee because it occurs extremely intermittently) The app is not running in the background, but... Could this be happening if there are a lot of pending operations in the background? I need help urgently

APNs Background Push Success but Wallet Pass Fails with ‘Unable to Deserialize JSON Payload’ on Device
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?

Periodic, seemingly global APNS disruptions
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).

Cannot receive APNs notification
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?

Silent push throttling breaking accessibility app for neurodivergent users
Hello all 👋 We're developing an app for families with neurodivergent members (primarily autistic children) and have run into a critical reliability issue with silent push notifications that breaks core functionality. Our current implementation: When a caretaker updates the person's daily routine/schedule in our system, we send a silent push notification to the user's device. The app wakes, connects to our server, downloads the updated schedule, and creates/updates local notifications for upcoming activities. The problem: Because the app is rarely/never directly interacted with by the end user (the child doesn't open the app - caregivers configure it on their behalf), silent push notifications get progressively throttled and eventually stop being delivered entirely. This means schedule changes made by caregivers never reach the device, breaking the app's core value proposition. Uninstalling and reinstalling doesn't reset the throttling state Questions: Is there any way to reset or mitigate throttling for devices that legitimately need background updates but have low or no user interaction? This is an accessibility use case where the end user (child) doesn't interact with the app, but the app must reliably receive updates. Would switching to regular (visible) push notifications avoid this throttling even if the app is not interacted with? We already have Critical Alerts entitlement, but for regular updates we're worried that the "CRITICAL ALERT" banner will be too upsetting for the child. Is there any exception process for accessibility apps to change the way Critical Alerts are presented? For neurodivergent individuals, predictable routines are essential. When schedule updates don't reach their device, it can cause significant distress. This is a genuine accessibility need, not a "nice-to-have" feature. Any guidance from Apple engineers or developers who've solved similar challenges would be greatly appreciated. Thank you!

Push Notifications
The following issue has occurred: Push notifications are not being received on certain devices. What could be the possible causes? Push notifications are being sent from our own server, and we are receiving normal responses from APNs. Users have confirmed that notifications are enabled on their devices, and they report no network issues. This problem is occurring for multiple users.

Posting a local notifications (or alert) from a launch agent
My Mac app has a launch agent (within the app bundle) that works great without the app running. There are some occasions where I need to display an alert and ask the user to launch the app to handle the issue. I thought about using UNUserNotificationCenter but I'm not able to make it work from the agent. I'm asking for authorization as follows: [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert | UNAuthorizationOptionSound | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error) { NSLog(@"authorization request completion. Granted: %@, error: %@ (%@)",granted?@"YES":@"NO",error, [error localizedDescription]); }]; And I'm trying to post the notification as follows: content.title = @"Your App Name"; content.body = @"Click the button to open the app"; content.sound = [UNNotificationSound defaultSound]; UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:[[NSUUID UUID] UUIDString] content:content trigger:nil]; [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) { if (error) { NSLog(@"Error showing notification: %@ %@", error, [error localizedDescription]); } }]; When running I'm getting asked to authorize, I authorize and all seems OK in system settings but I'm not able send any notifications. addNotificationRequest results in UNErrorCodeNotificationsNotAllowed error. I tried this with the authorization request inside the main app, or inside the agent, with the same results. When trying to post the notification from within the app, it does work, but that's not what I need. Is posting notifications from within the launch agent not possible at all, or is there anything here that I'm missing. TIA

Issue related to APNS is delivering expired voip push notification.
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.

Critical Notifications
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.

APNs Returning 200 OK for Uninstalled Apps Instead of 410 Error
We're experiencing an issue with Apple Push Notification service where APNs continues to return 200 OK responses for device tokens belonging to uninstalled applications. Issue Details: When sending push notifications to device tokens. APNs returns 200 OK responses even for devices where our app was uninstalled more than a month ago According to documentation(https://developer.apple.com/documentation/usernotifications/handling-notification-responses-from-apns), APNs should return 410 status code with JSON body for invalid tokens Expected Behavior: APNs should return 410 status code when device token is no longer valid (app uninstalled) Thanks in advanced for support

Background timer
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!

Critical Alerts and Notification Permissions
Back story: I'm developing an app that communicates with a personal medical device. We use critical alerts when we have hardware issues that could result in harm to the patient. The audio file is a 30 second file to make sure the patient is aware. If the app is open when they occur, we pop up a modal message in the app. When the user dismisses the notice, we call UNNotificationCenter::removeDeliveredNotifications(withIdentifiers:) to remove the critical alert and also to stop the audio file that is playing. This normally works fine. However we discovered that if the patient leaves critical alert enabled but disables notifications for our app, that we can still post the critical alert and it goes off. However when the user dismisses the message, the removeDeliveredNotifications call does not work. I did some debugging and if call getDeliveredNotifications with this permission combination, it return 0 (normally it would return 1). Does anyone know of another way to remove the critical alert in this situation? (or should I be submitting this as a bug?)

Concerning Socket Disconnection Issues in iPhone VoIP Applications
We are encountering the following issue with our VoIP application for iPhone, published on the App Store, and would appreciate your guidance on possible countermeasures. The VoIP application (callee side) utilizes a Wi-Fi network. The sequence leading to the issue is as follows: VoIP App (callee): Launches iPhone (callee): Locks (e.g., by short-pressing the power button) VoIP App (callee): Transitions to a suspended state VoIP App (caller): Initiates a VoIP call VoIP App (callee): Receives a local push notification VoIP App (callee): Creates a UDP socket for call control (for SIP send/receive) VoIP App (callee): Creates a UDP socket for audio stream (for RTP send/receive) VoIP App (callee): Exchanges SIP messages (INVITE, 100 Trying, 180 Ringing, etc.) using the call control UDP socket VoIP App (callee): Answers the incoming call VoIP App (callee): Executes performAnswerCallAction() Immediately after executing performAnswerCallAction() in the above sequence, the sendto() function for both the "UDP socket for call control (SIP send/receive)" and the "UDP socket for audio stream (RTP send/receive)" occasionally returns errno = 57 (ENOTCONN). (of course The VoIP app itself does not close the sockets in this timing) Given that the user has performed an answer operation, the iPhone is in an active state, and the VoIP app is running, what could be the possible reasons why the sockets suddenly become unusable? Could you please provide guidance on how to avoid such socket closures? Our VoIP app uses SCNetworkReachabilitySetCallback to receive network change notifications, but no notifications regarding network changes were received at the time errno = 57 occurred. Is it possible for sockets used by an application to be closed without any notification to the application itself?

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?

Silent push throttling breaking accessibility app for neurodivergent users
Hello all 👋 We're developing an app for families with neurodivergent members (primarily autistic children) and have run into a critical reliability issue with silent push notifications that breaks core functionality. Our current implementation: When a caretaker updates the person's daily routine/schedule in our system, we send a silent push notification to the user's device. The app wakes, connects to our server, downloads the updated schedule, and creates/updates local notifications for upcoming activities. The problem: Because the app is rarely/never directly interacted with by the end user (the child doesn't open the app - caregivers configure it on their behalf), silent push notifications get progressively throttled and eventually stop being delivered entirely. This means schedule changes made by caregivers never reach the device, breaking the app's core value proposition. Uninstalling and reinstalling doesn't reset the throttling state Questions: Is there any way to reset or mitigate throttling for devices that legitimately need background updates but have low or no user interaction? This is an accessibility use case where the end user (child) doesn't interact with the app, but the app must reliably receive updates. Would switching to regular (visible) push notifications avoid this throttling even if the app is not interacted with? We already have Critical Alerts entitlement, but for regular updates we're worried that the "CRITICAL ALERT" banner will be too upsetting for the child. Is there any exception process for accessibility apps to change the way Critical Alerts are presented? For neurodivergent individuals, predictable routines are essential. When schedule updates don't reach their device, it can cause significant distress. This is a genuine accessibility need, not a "nice-to-have" feature. Any guidance from Apple engineers or developers who've solved similar challenges would be greatly appreciated. Thank you!

The APP was not awakened by system after start a liveactivity and the liveactivity has showed on lock screen.so the updatetoken wont send to our inner server and the liveactivity can not update,often like this,but sometimes it can work. it makes me confuse,and i don't know how should i can do,because the liveactivity like a black box,i can not analyse the data link.for example ,inner server send a start liveactivity,but it can not accept a updatetoken unless the user lanuch APP. i hope the liveactivity can start and update on background.

Push Notifications
The following issue has occurred: Push notifications are not being received on certain devices. What could be the possible causes? Push notifications are being sent from our own server, and we are receiving normal responses from APNs. Users have confirmed that notifications are enabled on their devices, and they report no network issues. This problem is occurring for multiple users.

Posting a local notifications (or alert) from a launch agent
My Mac app has a launch agent (within the app bundle) that works great without the app running. There are some occasions where I need to display an alert and ask the user to launch the app to handle the issue. I thought about using UNUserNotificationCenter but I'm not able to make it work from the agent. I'm asking for authorization as follows: [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert | UNAuthorizationOptionSound | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error) { NSLog(@"authorization request completion. Granted: %@, error: %@ (%@)",granted?@"YES":@"NO",error, [error localizedDescription]); }]; And I'm trying to post the notification as follows: content.title = @"Your App Name"; content.body = @"Click the button to open the app"; content.sound = [UNNotificationSound defaultSound]; UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:[[NSUUID UUID] UUIDString] content:content trigger:nil]; [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) { if (error) { NSLog(@"Error showing notification: %@ %@", error, [error localizedDescription]); } }]; When running I'm getting asked to authorize, I authorize and all seems OK in system settings but I'm not able send any notifications. addNotificationRequest results in UNErrorCodeNotificationsNotAllowed error. I tried this with the authorization request inside the main app, or inside the agent, with the same results. When trying to post the notification from within the app, it does work, but that's not what I need. Is posting notifications from within the launch agent not possible at all, or is there anything here that I'm missing. TIA

Issue related to APNS is delivering expired voip push notification.
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.

Critical Notifications
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.

APNs Returning 200 OK for Uninstalled Apps Instead of 410 Error
We're experiencing an issue with Apple Push Notification service where APNs continues to return 200 OK responses for device tokens belonging to uninstalled applications. Issue Details: When sending push notifications to device tokens. APNs returns 200 OK responses even for devices where our app was uninstalled more than a month ago According to documentation(https://developer.apple.com/documentation/usernotifications/handling-notification-responses-from-apns), APNs should return 410 status code with JSON body for invalid tokens Expected Behavior: APNs should return 410 status code when device token is no longer valid (app uninstalled) Thanks in advanced for support

Background timer
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!

Critical Alerts and Notification Permissions
Back story: I'm developing an app that communicates with a personal medical device. We use critical alerts when we have hardware issues that could result in harm to the patient. The audio file is a 30 second file to make sure the patient is aware. If the app is open when they occur, we pop up a modal message in the app. When the user dismisses the notice, we call UNNotificationCenter::removeDeliveredNotifications(withIdentifiers:) to remove the critical alert and also to stop the audio file that is playing. This normally works fine. However we discovered that if the patient leaves critical alert enabled but disables notifications for our app, that we can still post the critical alert and it goes off. However when the user dismisses the message, the removeDeliveredNotifications call does not work. I did some debugging and if call getDeliveredNotifications with this permission combination, it return 0 (normally it would return 1). Does anyone know of another way to remove the critical alert in this situation? (or should I be submitting this as a bug?)

Concerning Socket Disconnection Issues in iPhone VoIP Applications
We are encountering the following issue with our VoIP application for iPhone, published on the App Store, and would appreciate your guidance on possible countermeasures. The VoIP application (callee side) utilizes a Wi-Fi network. The sequence leading to the issue is as follows: VoIP App (callee): Launches iPhone (callee): Locks (e.g., by short-pressing the power button) VoIP App (callee): Transitions to a suspended state VoIP App (caller): Initiates a VoIP call VoIP App (callee): Receives a local push notification VoIP App (callee): Creates a UDP socket for call control (for SIP send/receive) VoIP App (callee): Creates a UDP socket for audio stream (for RTP send/receive) VoIP App (callee): Exchanges SIP messages (INVITE, 100 Trying, 180 Ringing, etc.) using the call control UDP socket VoIP App (callee): Answers the incoming call VoIP App (callee): Executes performAnswerCallAction() Immediately after executing performAnswerCallAction() in the above sequence, the sendto() function for both the "UDP socket for call control (SIP send/receive)" and the "UDP socket for audio stream (RTP send/receive)" occasionally returns errno = 57 (ENOTCONN). (of course The VoIP app itself does not close the sockets in this timing) Given that the user has performed an answer operation, the iPhone is in an active state, and the VoIP app is running, what could be the possible reasons why the sockets suddenly become unusable? Could you please provide guidance on how to avoid such socket closures? Our VoIP app uses SCNetworkReachabilitySetCallback to receive network change notifications, but no notifications regarding network changes were received at the time errno = 57 occurred. Is it possible for sockets used by an application to be closed without any notification to the application itself?
