AWS SNS False Success Delivery
We operate a social network application, SportsYou with over 3 million monthly active users and are experiencing significant issues with push notification delivery through APNs. We have a large number of users reporting they are not receiving push notifications. Our infrastructure uses AWS SNS integrated with APNs to deliver notifications. However, AWS CloudWatch consistently reports successful delivery (Success response), even though users confirm they never received the notifications. Because we receive success responses from AWS SNS, our system does not attempt to recreate or refresh the device endpoints. This leaves us unable to detect or recover from these delivery failures automatically. This issue is widespread and inconsistent. It affects users across multiple variables including different iOS versions, different device models, and different versions of our application. We cannot identify a clear pattern that would help us isolate the root cause. With millions of active users, even a small percentage of delivery failures represents thousands of users experiencing a degraded service. This is significantly impacting user engagement and satisfaction. We need guidance on how to properly diagnose this issue and ensure reliable notification delivery to our users. Specifically, we'd like to understand why we're receiving success responses when notifications aren't being delivered, and what steps we can take to detect and prevent these failures.

Push notifications don't deliver when device is idle on iOS 18.7 and 26.0
There's a list of bug reports: FB19778882 FB19813796 FB19852724 FB19767262 FB20378888 FB20379383 FB20394663 Me and many other users have issue with push notifications. To reproduce this you should do this steps: Lock iPhone and make it idle for 10+ minutes; Send any message from other device via third-party app that uses push notifications (WhatsApp, Telegram and etc.); After few attempts you can see, that messages don't deliver. They delivers immediately when I unlock iPhone or go to the app. This bug reproduces on iOS 18.7 and 27. As I think iPhone goes to deep sleep after 10+ minutes after it locked and don't get push notifications. I've tried everything: many of settings, DFU without backup, but nothing helps to resolve this issue. Pay attention, please, cause this bug is very annoying and present on iOS 18.7 (that is the last for many devices) and latest iOS 26. Thanks!

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!

Apple Push Notification service server certificate Was the update published as scheduled?
I tried below at 2:00 PM on 21/01/2025(JST). Apple Push Notification service server certificate update I followed above, a new server certificate: "SHA-2 Root : USERTrust RSA Certification Authority certificate" was added to my push server, but a certificate error occurred and push notifications could not be sent. So I refered this article,Instead of connecting via DNS name resolution at api.development.push.apple.com, I fixed api.development.push.apple.com to "17.188.143.34" in /etc/hosts, I could push notifications with the new server certificate. (I got this IP(17.188.143.34) from this airtcle) From this, I suspect that Apple had not yet updated the APNs certificate (CA) for the Sandbox environment as of 2:00 PM on January 21, 2025 (JST). Was the update published as scheduled?

didRegisterForRemoteNotificationsWithDeviceToken Not Called on iOS 18.1.1
I'm experiencing issues with didRegisterForRemoteNotificationsWithDeviceToken not being called on iOS 18.1.1. Here's what I've tried: Basic Setup: Properly configured UNUserNotificationCenter Requested permissions with requestAuthorization(options:) Registered for remote notifications with registerForRemoteNotifications() Environment: Xcode 16.3 iOS 18.1.1 (physical device) Firebase (tried with and without it) Troubleshooting: Verified provisioning profile includes Push Notifications Confirmed APNs certificate is valid Disabled Firebase's method swizzling Tested on a clean project (works fine) Checked device logs (no relevant errors) Code Snippet: // In AppDelegate.swift public func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { let tokenParts = deviceToken.map { data in String(format: "%02.2hhx", data) } let tokenString = tokenParts.joined() print("📱 Device Token: \(tokenString)") // Store the token for your backend UserDefaults.standard.set(tokenString, forKey: "deviceToken") // Send to backend Task { do { try await APIService.shared.setDeviceToken(tokenString) } catch { print("❌ [AppDelegate] Failed to send device token to backend: \(error)") } } } public func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil) -> Bool { // IMPORTANT: First handle push notification registration UNUserNotificationCenter.current().delegate = self // Request notification permissions self.requestNotificationPermissions() // Register for remote notifications DispatchQueue.main.async { UIApplication.shared.registerForRemoteNotifications() } return true } private func requestNotificationPermissions() { UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { granted, error in guard granted else { print("❌ Notification permission not granted") return } print("✅ Notification permission granted") } }

Status of Notification Service Extension filtering entitlement
Hi Apple engineering team, I contacted Developer Support regarding the status of our entitlements request, and they recommended that I post here for visibility. It’s been just over two weeks since we submitted the request, and we haven’t received any updates yet. We understand these requests can take time, but it’s unclear what the typical timeline looks like or if there’s any way to check on the progress. Is there a way to get an update or better understand where we are in the process? We’re trying to plan our release and would really appreciate any guidance on what to expect. Thanks in advance for your help.

Several pushes and lifetime
Hello everyone. I'm trying to add a lifetime for push notifications via apns-expiration for my application. With the Internet turned on, push notifications come, that's ok. With the Internet turned off, as I noticed, only the last push with the badge installation on the application icon comes. That is, the logic is that a text push with text is sent, then after N time the next push to the same device with the badge installation. I would like to receive a text push after turning on the Internet.

PushKit (VoIP) delivery issue — user’s device fails to receive VoIP pushes; logging in on that device suppresses VoIP pushes for all devices of that user
We are facing an issue where VoIP notifications are not delivered to a user's device. If we login with the user credentials on another device the VoIP notifications are being received, if he logs in on his device VoIP notifications are not being received anymore on all devices. So When the user logs in on the affected device, all devices on that account stop receiving VoIP pushes (including the affected one). Logging out on the affected device restores delivery to other devices. What could cause this issue? It's only happening for this user so the configuration and mobile app PushKit code is working as intended.

Server notifications v2 UNSUCCESSFUL_HTTP_RESPONSE_CODE
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?

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

Push Notifications
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。

Persistent iOS Signing & UIBackgroundModes Entitlement Issue
Problem Statement We are experiencing a critical and persistent issue preventing the successful signing and building of our iOS application. The core problem is that provisioning profiles, whether automatically generated by Xcode or manually created in the Apple Developer Portal, consistently fail to include the UIBackgroundModes entitlement, leading to a build failure. Specific Question Why are provisioning profiles generated via the Apple Developer Portal and/or Xcode's automatic signing process consistently omitting the UIBackgroundModes entitlement for our App ID, even when this capability is explicitly configured in Xcode? We seek guidance or backend intervention to ensure our provisioning profiles include the necessary entitlement. Expected Outcome We expect to be able to successfully build and sign our iOS application, with provisioning profiles that correctly include the UIBackgroundModes entitlement, allowing for proper implementation of remote notifications. Observed Symptoms Primary Build Error: Consistent build failure with the exact error message: "Automatic signing failed: Provisioning profile 'iOS Team Provisioning Profile: com.scott.ultimatefix' doesn't include the UIBackgroundModes entitlement." Missing Entitlement in Profile (Confirmed by Inspection): Direct inspection of downloaded .mobileprovision files (including those manually generated in the Developer Portal for com.scott.ultimatefix) consistently shows the absence of the UIBackgroundModes entry within the section of the Entitlements dictionary. The aps-environment key for Push Notifications is present, indicating Push Notifications are enabled, but Background Modes are not. Certificates Correctly Recognized in Xcode: Our "Apple Development: Stephen Criscell Scott" and "Apple Distribution: Stephen Criscell Scott" certificates are correctly displayed and recognized in both Keychain Access and Xcode's Preferences > Accounts > Manage Certificates window (without "Not in Keychain" status). Furthermore, the Signing & Capabilities tab for the target in Xcode now correctly shows Signing Certificate: Apple Development: Stephen Criscell Scott. Persistent Issue Across Resets: The problem persists despite extensive local cache invalidation, Xcode reinstallation, and even testing in a fresh macOS user account (which confirmed the issue was not user-specific).
