React Native iOS - Notification Service Extension Not Working
I've added a Notification Service Extension as a target to my React Native iOS app following Apple's official documentation. After completing all the setup steps as outlined in the documentation, the notification titles remain unchanged - notifications are arriving without any modifications, suggesting the extension isn't functioning properly.Testing Details: Sending notifications via Apple Push Notification Console Tested on iPhone 16 Pro Max (physical device) Tested on iPhone 15 Pro simulator Both show the same issue - no title modifications The extension appears to not be executing at all. Has anyone encountered similar issues with Notification Service Extensions in React Native projects, or can suggest troubleshooting steps to verify the extension is properly configured and running?

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).

NSUserNotificationsUsageDescription only works for certain locales
I'm trying to provide custom localized descriptions for the iOS notification permission popup in my app, which supports multiple locales. To achieve this, I'm using InfoPlist.strings files per locale with the following keys: NSUserNotificationsUsageDescription NSUserTrackingUsageDescription The issue I'm facing is that NSUserTrackingUsageDescription is working correctly across all tested locales, but NSUserNotificationsUsageDescription only works for some locales. Locales tested: Working: ja, tr, fr-CA Not working: fr-BE, nl-BE In each case, the correct localized NSUserTrackingUsageDescription appears, but the NSUserNotificationsUsageDescription falls back to the default or does not appear as expected in fr-BE and nl-BE. I'm using Xcode 16 and testing on both iOS 18 simulator and physical devices, and the issue is consistent across both. Any insights on whether this is a known issue in iOS or if there are additional steps needed for NSUserNotificationsUsageDescription to localize properly would be greatly appreciated.

How can I check applicationState by tap anps push cards?
when I implementation the UNUserNotificationCenterDelegate func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) { var status = "" if (UIApplication.shared.applicationState == .active) { status = "active" } else if (UIApplication.shared.applicationState == .background) { status = "background" } else if (UIApplication.shared.applicationState == .inactive) { status = "inactive" } completionHandler() } I find that UIApplication.shared.applicationState == .background this case can not execute when application is in background。 why applicationState is inactive not background?

Smart Adaptive Volume & Brightness - Say Goodbye to Noise & Visual Pollution!
Hello everyone in the iOS Devolution community! I'd like to share a suggestion that I believe would bring an unprecedented level of intelligence and comfort to the daily iPhone experience: Smart Adaptive Volume & Brightness. The Problem We Aim to Solve How many times has your iPhone rung too loudly in a quiet environment, embarrassing you in a meeting or waking someone up? Or, the opposite, you missed an important call on a busy street because the volume was too low? And what about screen brightness? It's a constant adjustment: too bright in the dark, hard to see in the sun. Currently, we have to manually adjust volume and brightness, or rely on Auto-Brightness (which only works for the screen) and Focus modes, which can be a bit "all or nothing." This leads to interruptions, frustration, and that feeling that your phone isn't really adapting to you. The Solution: Smart Adaptive Volume & Brightness My proposal is for iOS to use the iPhone's own sensors to dynamically adapt notification and ringtone volume, and screen brightness, to the environment we're in. How it would work in practice: Environmental Scan Before Ringing/Displaying: When a notification (call, message, app alert) is about to be delivered, and even before it makes a sound, the iPhone would briefly activate its sensors. The microphone would read the ambient noise level (in decibels), but without recording audio or analyzing any content. Just the "noise" of the surroundings. The ambient light sensor would assess the light intensity around the device. Intelligent and Coordinated Adjustment: Based on these combined readings of noise and brightness, iOS would make the adjustments: In noisy and bright environments (e.g., on the street during the day): The ringtone volume would be automatically increased to ensure you hear it, and the screen brightness would also be raised to facilitate viewing in strong light. In quiet and dark environments (e.g., cinema, bedroom at night): The volume would be discreetly reduced to avoid disturbances, and the screen brightness would be dimmed for your visual comfort and to avoid bothering others. Adjustments would be gradual, adapting to any type of environment (office, cafe, etc.). User Control: Of course, we'd have the option to enable or disable "Smart Adaptive Volume & Brightness" in the settings. We could also define minimum and maximum limits for these automatic adjustments, ensuring the iPhone adapts to our personal comfort levels. This feature would complement existing Focus modes, operating within the permissions of any active Focus. The Benefits for the User Goodbye to Inconvenient Interruptions: No more startling loud rings in quiet places. Never Miss a Call Again: In noisy environments, your iPhone will adapt to be heard. Constant Visual Comfort: The screen will always be at the ideal brightness, without blinding you in the dark or disappearing in the sun. Smoother Experience: Fewer manual adjustments, more time to focus on what matters. Guaranteed Privacy: The use of microphones and sensors would be strictly for environmental measurement, without recording or analyzing personal data. I believe this feature would bring a new level of intelligence and usability to iOS, making the iPhone even more intuitive and adapted to our daily lives. What do you all think of this idea?

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.

Badge Number Persists When Re-Installing Application
I have been working on adding a badge number count to my app, but have run into a really weird edge case. If I have a badge number on my app, delete the application and then re-install it, the badge number still persists on the app icon until I first open the app. I tried looking to see if there is a lifecycle method that is triggered upon uninstalling an app as well as if there is a specific userDefaults attribute to check in order to clear the badge, but I can't find any clear solutions. Does anyone know of a fix to this issue?

How can you tick between live activities?
I have been watching the following moment from wwdc (Design dynamic Live Activities): https://developer.apple.com/videos/play/wwdc2023/10194/?time=728 It suggest that you should 'tick' between multiple live activities of your app: When you want to show multiple sessions for your app going on at once, consider ticking between the display of them to continue to give users an eye on everything that’s going on. How can I tick between them? More specifically how can I do that when my app is in the background?
