How to start live activity in terminated state?
Hi everyone and Apple support, I’ve built an app that continuously runs and receives temperature data from a sensor. When a threshold is reached, I use Live Activities with the push notification flow to display alerts on the Dynamic Island. The Live Activity and push notification flow work fine in foreground and background states. However, I’m trying to support push-triggered Live Activities when the app is in the terminated state. Since my app rarely terminates, I can’t confirm if the Live Activity push token is generated in that state. It seems like it isn’t, which blocks the Live Activity from starting via push. I tried with both pushtostarttoken and pushtostarttokenupdates. None of them worked. Has anyone dealt with this or found a workaround to ensure the push token is available even when the app is terminated?

SpringBoard Crashes on macOS Simulator When Receiving Critical Alerts
I’m experiencing a consistent crash of SpringBoard on macOS when running my iOS app in the Simulator. The crash occurs specifically when a critical alert (geofence notification) is triggered by my server and delivered to the app. Xcode version: 16.4 macOS version: 15.5 App uses UNUserNotificationCenter with critical alert notifications related to geofencing. When the critical alert is received, SpringBoard quits unexpectedly on macOS, crashing the Simulator UI to the home screen. The notification is delivered by Firebase, and I have updated to the latest version of that. The console shows: XPC connection interrupted [C:1] Error received: Connection interrupted. [C:1-2] Error received: Connection interrupted. This does not happen when testing on a real device — the app works fine there, however, Springbaord still crashes on macOS. Please advise if this is a known issue or if there’s a workaround. This severely impacts development and testing of location-based critical notifications. The last time I tested this functionality, with an older version of Xcode, I had no issues. Thank you for your help.

didReceive isn't called in CarPlay scene
I have set up an iOS application with CarPlay scene using carplay-driving-tasks entitlement. And as per latest policy changes I'm able to get push notifications in the CarPlay screen. But unlike from phone scene, when I tap on a notification from CarPlay I don't get a trigger on didReceive method to intercept the payload of the notification that user tapped on. Is there any other ways or configuration needed to get this working? I just need to get the payload and present an Alert template within the CarPlay when user taps on a CarPlay notification and the app opens.

Notification Service Extension and the main thread
Question, if I am writing async code in the notification service extension, I understand it terminates after 30 seconds. If I want to wait until these async methods finish before calling the content handler, I believe an option I have is to use dispatch groups. However I am open to other solutions if there are better options. My question is, if I use dispatch groups, is there any issue in using the main queue here? Or does the main thread not make sense to use in the context of the NSE? dispatch_group_notify(group, dispatch_get_main_queue(), ^{ if (self.contentHandler) { self.contentHandler(self.bestAttemptContent); } }); Or is it recommended to instead use a different queue in the NSE? dispatch_queue_t nseQueue = dispatch_queue_create("com.blah.blah.nse.queue", DISPATCH_QUEUE_SERIAL); dispatch_group_notify(group, dispatch_get_global_queue(QOS_CLASS_(SOMETHING), 0), ^{ ... }); OR am I over thinking this? :) Thanks ahead of time, relatively new to iOS so just looking to learn/understand better.

How to correctly convert the bytes type devicetoken obtained from the MDM description file to the 16-bit hexadecimal data required by APNS?
I have converted a large part of the data, but only 5% of the data was successfully converted. The failed devicetoken shows "bad devicetoken" when accessing APNS. Here are examples of failed conversions devicetoken. Is there any official documentation for this part? DeviceToken Orgin \xc2\xa1\xcb\x9cr\xc3\x81\xe2\x80\x9e\x01b\xc3\xbce1pf\t\xc2\xa7\xc3\x82v}\xc3\xa1\xc3\x9a:?\r\n\xc3\xa5\xc6\x92\xc3\xb7y\xc3\x9e\xe2\x80\x9c\xc3\x89r

The push notification icon is still displaying the old version
Hello guys, We have updated our app icon, and it is correctly reflected in our app build and assets. However, the push notification icon is still displaying the old version for some users. ✅ We have verified that: All icon assets in Assets.xcassets match the new icon. The app icon has been updated in Info.plist. The app has been resubmitted and approved on the App Store. ❌ However, some users still see the old notification icon, even after reinstalling the app. Restarting the device does not always resolve the issue. Could you provide insights into how iOS caches notification icons and how we can force a refresh for all users?

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.

No notification sound when CarPlay is connected
We're building a taxi driver app. Our goal is simple: Play a notification sound when a new ride request arrives — even if the iPhone is connected to CarPlay. We use Firebase push with "sound": "default" and "interruption-level": "time-sensitive". The app requests .carPlay and uses a category with .allowInCarPlay. Everything works when CarPlay is disconnected — we get sound and banner. But when connected to CarPlay: the push is delivered silently, no sound is played (even on the phone), Siri Announce is enabled, but nothing is spoken. Questions: Is notification sound blocked when CarPlay is active, unless the app has CarPlay entitlement? Is Siri Announce the only way to notify the driver audibly in this case? Would getting a CarPlay entitlement (e.g. CarPlay.communication) fix this without building a full CarPlay UI? Thanks — all we need is a reliable sound alert when a new ride comes in.

Apple wallet push notifications have stopped working.
I've been using Apple's push service for pass notifications for years (since 2012) and everything has been working fine until recently. With no code changes, the push service has stopped working. Passes can still be installed on the device and pull to refresh does get the updates and highlights changes properly, so the pass signing is working properly, it's just the push notices don't seem to be getting to the device. I am getting log messages back from the APNS, and fwrite is returning the number of bytes written so I don't think there are any authentication issues. I'm using PHP on my own web server in case that's relevant. I also disabled rate limiting in the developer settings on my device to make sure that isn't the issue. I've also verified there are no outstanding messages in the feedback service (which also works fine without any errors). In fact, there are no errors and acting like everything is working which is why it is frustrating to troubleshoot since the problem seems to be between Apple and the device. I don't know if this may be related, but I know I saw this post from apple about a certificate change: https://developer.apple.com/news/?id=09za8wzy I have checked that the server has the new certificate per the instructions in this post: https://developer.apple.com/forums/thread/772665 Still no push updates work, however the Lock Screen location messages do appear and pass update notifications do appear on the Lock Screen correctly but only after pulling to refresh on the back of the pass. Does anyone have any ideas on how to fix or even start troubleshooting why the pushes aren't being delivered to the phone?

CarPlay: no banner or sound for APNs while connected, works on phone (iOS 18.0, UNNotificationCategoryOptions.allowInCarPlay)
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. Environment iPhone 13 Pro, iOS 18.0 CarPlay head-unit: Xcode 16.2 CarPlay Simulator App built with Flutter 3.22 + firebase_messaging: ^15.2.5 Deployment target: iOS 14.0 Xcode capabilities enabled: Push Notifications, Time-Sensitive Notifications App settings on the device: Allow Notifications -› Sounds ON, Show in CarPlay ON Siri › Announce Notifications › CarPlay: master toggle ON + my app added to the allowed list Driving Focus = Off (same result if it’s On) Native setup in AppDelegate.swift UNUserNotificationCenter.current().requestAuthorization( options: [.alert, .sound, .badge, .carPlay] ) { _,_ in } let carPlayCategory = UNNotificationCategory( identifier: "CARPLAY_ORDER", actions: [], intentIdentifiers: [], options: [.allowInCarPlay] ) UNUserNotificationCenter.current().setNotificationCategories([carPlayCategory]) UNUserNotificationCenter.current().delegate = self application.registerForRemoteNotifications() APNs payload that I send via FCM { "aps": { "alert": { "title": "New test order", "body": "Location info test" }, "sound": "default", "category": "CARPLAY_ORDER", "interruption-level": "time-sensitive", "relevance-score": 1 } } What could be the problem? Please help me solve the error

How to send PTT push for incomingServiceUpdatePush?
I was recently made aware of a relatively new method on PTChannelManagerDelegate that allows the backend infrastructure to update the PTT service on a device. incomingServiceUpdatePush(channelManager:channelUUID:pushPayload:isHighPriority:remainingHighPriorityBudget:completion:) I remember the person stated that there was a specific format that the payload must have, but I am unable to find any documentation about it. Can somebody point me to documentation on how to send this type of push notification for incomingServiceUpdatePush or give me an example payload? I believe it uses the same PTT push token, but if the headers are different, then please specify those differences too. Thanks!

After debugging i noticed that com.apple.developer.voip entitlement wasnt included which i later added, trying to create a build i get the eas error that the entitlement wasnt added to the identifier capabilities. My issue now is that i can't seem to find the voip capability to check in the identifiers capabilities list for the bundle id.d
