(Xcode 26.2, iPhone 17 Pro) I can't seem to get hardware tag checks to work in an app launched without the special Hardware Memory Tagging diagnostics. In other words, I have been unable to reproduce the crash example at 6:40 in Apple's video Secure your app with Memory Integrity Enforcement. When I write a heap overflow or a UAF, it is picked up perfectly provided I enable the Hardware Memory Tagging feature under Scheme Diagnostics. If I instead add the Enhanced Security capability with the memory-tagging related entitlements: I'm seeing distinct memory tags being assigned in pointers returned by malloc (without the capability, this is not the case) Tag mismatches are not being caught or enforced, regardless of soft mode The behaviour is the same whether I launch from Xcode without Hardware Memory Tagging, or if I launch the app by tapping it on launchpad. In case it was related to debug builds, I also tried creating an ad hoc IPA and it didn't make any difference. I realise there's a wrinkle here

A good place to start here is Enabling enhanced security for your app. The only one of these settings that actively reduces security is Enable Soft Mode for Memory Tagging. However, that currently has no effect because our shipping systems run all third-party apps is soft mode regardless of that setting. See this thread for more about that. Be aware that certain settings can cause problems with deploying to systems prior to xyzOS 26.0. We’ve fixed this in Xcode 26.4 beta. See the Xcode 26.4 Beta Release Notes for more (search for 168185600). But, generally, my general advice is that you enable all the extra stuff and then only disable something if it causes problems that you can’t otherwise resolve. Finally, there are a couple of upcoming Meet with Apple sessions focused on security, and those are a great opportunity to learn more about this. See here.

Historically there was no supported way to transfer an app group ID between teams, so my advice has always been to simply create a new app group ID in the new team and have the new app and its appex use that app group. However, there’s been a recent development in this space. I’m currently researching that, and I’ve made a note to come back here once I learn more.

I have an iOS app with App Groups. The app uses the CallKit extension for call block functionality. All data is stored in UserDefaults(suiteName:) and FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: ). I am planning to transfer this app to a different Apple Developer account and would like to clarify how App Groups behave after the transfer: Will my main app Target and CallKit Extensions keep access to the same AppGroups containers with the new Team ID? I will recreate the same AppGroups container identifiers on a new account but my concern is about Team ID change, that can lead to loss access to original containers and all data from previous Team ID. I need to clearly understand whether the app can continue accessing the existing App Group container after the Team ID changes, or if I must manually back up data before transfer and restore all data after transfer completed. As long as the App Group still exists on the original developer account and the user has not updated the

Dear Apple Support Team, Thank you for your continued support. I would like to inquire about the behavior of CallKit. Our company provides an office PBX extension phone application (iPhone app). When the iPhone is placed into sleep mode (screen off) and our app receives an incoming call, the following sequence sometimes results in an audio playback panel appearing at the bottom of the lock screen for a few seconds after the call ends(See attachment file for detail). Sequence to reproduce the issue: Put the iPhone into sleep mode (screen off). Receive an incoming call to our extension phone app. CallKit incoming call screen appears. Answer the call. Conduct the call. End the call from the peer. iOS versions with confirmed behavior: iOS 26.0: Not observed. iOS 26.2: Observed. iOS 26.3: Not observed. This behavior does not affect the call functionality itself; however, some users report that the temporary appearance of the audio playback panel feels unusual. If there is any known reason for this behavio
@KayleeSC How did you get the bloomFilter hash correct? I followed your process from earlier in this thread. I used the MurmurHash3 swift library, but the standard FNV-1a implementation instead of the inverted order of operations you suggested. (An apple dev told me to do it this way) The hash this produces still isn't blocking sites for me. Is this the hash you got for the 10 example websites in the starter code?

My app was reviewed and approved on Feb 3rd, and still does not show in app store. I have submitted a ticket to Apple Feb 3rd, and still have not received a reply. I get either 404, or this app is not available your country or region. This does it for me, and anyone I've asked to try it. This is very confusing - please someone help! https://apps.apple.com/us/app/exp-lights/id6758403863
I've followed the setup process to get Apple Hosted Background Assets configured for my project. (https://developer.apple.com/documentation/backgroundassets/downloading-apple-hosted-asset-packs) But when I build and run the app I get the following error... BackgroundAssets/AssetPackManager.swift:174: Fatal error: The process lacks a team ID. I've checked the Signing->Team for both targets and they both have my Team associated. Any help or advice would be appreciated...
Dear Apple Team, I am writing regarding our pending account termination.

The corrected version is currently In Review. With the February 24 deadline approaching and no feedback received through any channel, we are concerned about the status of our appeal. We remain fully committed to compliance and respectfully request confirmation that our appeal is being reviewed. Thank you.
Hello Apple Developer Support, We are observing inconsistent behavior with push notification sounds routing to Bluetooth / external speakers. Our app sends push notifications with a custom sound file using the sound parameter in the APNs payload. When an iPhone is connected to a Bluetooth speaker or headphones: On some devices, the notification sound plays through the connected Bluetooth/external speaker. On other devices, the notification sound plays only through the iPhone’s built-in speaker. We also tested with native apps like iMessage and noticed similar behavior — in some cases, notification sounds still play through the phone speaker even when Bluetooth is connected. Media playback (e.g., YouTube or Music) routes correctly to Bluetooth, so the connection itself is functioning properly. We would like clarification on the following: Is this routing behavior expected for push notification sounds? Are notification sounds intentionally restricted from routing to Bluetooth in certain conditions (e.g
Do you have a feedback report yet? If not, would you mind to file one with a sysdiagnose captured in the way mentioned here, and then share your report ID? Folks reported pairing & connection issues between Xcode and Apple watch in this thread, and so most likely the Xcode team knows the issue. Filing your own feedback report will help the team to be sure that what you are encountering is the same issue. Best, —— Ziqiao Chen Worldwide Developer Relations.

Does the App Review process have access to Apple-Hosted Asset Packs during review? My app uses Asset Packs to offer a library of data to the end-user (with a workaround, if unavailable), but I am frequently seeing the workaround screen in App Review with errors I haven't seen elsewhere. The latest error I encountered (via the App Review team's feedback) was: A server with the specified hostname could not be found. thrown from (to my belief) AssetPackManager.shared.ensureLocalAvailability. This is unexpected to me, as both this code as well as the asset packs have already been released and are working reliably in production. Has anyone else experienced these issues?
I have the exact same issue. It would be great to get some insight from Apple on this.

Hello Apple Developer Community, I'm developing a cross-platform app using Flutter and the flutter_beacon library to handle iBeacon detection on iOS. My goal is to wake up the app in the background when it's in a killed/terminated state upon entering/exiting beacon regions, allowing for BLE communication (e.g., ranging or connecting to beacons). I've configured the necessary Info.plist keys for always location access and background location modes, and it works partially for single regions, but I have some specific questions/issues regarding reliability and limitations: Background Execution Time After Wake-Up: When the app is woken in the background by a region monitoring event (enter/exit) from a killed state, approximately how much time (in seconds) does iOS allocate for the app to run before suspending it again? Is this sufficient for performing BLE operations like ranging beacons or establishing a short connection, or are there stricter limits in terminated wake-ups compared to standard background
