Overview

We are developing a standalone AI avatar application for hospital reception kiosks using Mac mini (M2/M4). The app runs on SwiftUI + RealityKit, displays on a 75-inch monitor, and utilizes a USB-connected 4K camera and external sensors (LiDAR/mmWave). We have several technical concerns regarding the transition from iPadOS to macOS. Could you please provide insights on the following? ARKit/Vision Framework on macOS with External Camera On iPadOS, ARKit provides robust Face Tracking. On macOS with an external USB 4K camera: Can we achieve real-time face tracking (expression/gaze/depth) with Vision framework or ARKit comparable to iPadOS performance? Are there any specific limitations for accessing the Neural Engine via Vision framework for real-time 4K video analysis on macOS? Accessing External Hardware (LiDAR/Sensors) in Sandbox We plan to connect external LiDAR and mmWave sensors (e.g., Akara) via USB/Bluetooth. Is it feasible to communicate with these custom drivers/devices within the App Sandbox environment? Would DriverKit be required, or can we use standard serial communication APIs? On-Device LLM (MLX) & Thermals We intend to run a local LLM (e.g., Llama 3 using MLX framework) for offline conversation, alongside 3D rendering. With the M2/M4 Mac mini fan design, is there a risk of thermal throttling during 10+ hours of continuous operation (simultaneous CoreML + 3D rendering)? Is the Mac Studio recommended over the Mac mini for this thermal profile? Long-running Speech API Are there any known issues (memory leaks, API limits) when using Spherch framework and AVSpeechSynthesizer continuously for over 10 hours daily? 3D Display Output Are there any macOS constraints for rendering a SwiftUI window in a specific 3D format (e.g., Side-by-Side) and outputting it via HDMI to a 3D digital signage display (fixed refresh rate/resolution)? Thank you for your assistance.

Downloaded example app from here Xcode version: Version 26.1.1 (17B100) Simulator iOS Version: 26.1 & 18.5 Set custom location in the simulator to the center of the condition being monitored in the example. The only log entry was "Setup Monitor". Tried a custom gpx starting at the same point and moving 500m away. Same logs. Didn't change any of the source code, granted always permissions, allowed notifications, tapped "AddCircularGeographicCondition". Let me know if there is something I am missing or more information I can provide.

I'm working on my first model that detects bowling score screens, and I have it working with pictures no problem. But when it comes to video, I have a sizing issue. I added my model to a small app I wrote for taking a picture of a Bowling Scoring Screen, where my model will frame the screens in the video feed from the camera. My model works, but my boxes are about 2/3 the size of the screens being detected. I don't understand the theory of the video stream the camera is feeding me. What I mean is that I don't want to make tweaks to the size of my rectangles by making them larger, and I'm not sure if the video feed is larger than what I'm detecting in code. Questions I have are like is the video feed a certain resolution like 1980x something, or a much higher resolution in the 12 megapixel range? On a static image of say 1920x something, My alignment is perfect. AI says that it's my model training, that I'm training on square images but video is 16:9. Or that I'm producing 4:3 images in a 16:9 environment. I'm missing something here but not sure what it is. I already wrote code to force it to fit, but reverted back to trying for a natural fit.

Since the introduction of the siblings / and /System/Volumes/Data architecture, some very basic, critical commands seems to have a broken behaviour ( cp, rsync, tar, cpio…). As an example, ditto which was introduced more than 10 years ago to integrate correctly all the peculiarity of HFS Apple filesystem as compared to the UFS Unix filesystem is not behaving correctly. For example, from man ditto: --rsrc Preserve resource forks and HFS meta-data. ditto will store this data in Carbon-compatible ._ AppleDouble files on filesystems that do not natively support resource forks. As of Mac OS X 10.4, --rsrc is default behavior. [...] --extattr Preserve extended attributes (requires --rsrc). As of Mac OS X 10.5, --extattr is the default. and nonetheless: # ls -@delO /private/var/db/ConfigurationProfiles/Store drwx------@ 5 root wheel datavault 160 Jan 20 2024 /private/var/db/ConfigurationProfiles/Store                            ********* com.apple.rootless 28 *************************** # mkdir tmp # ditto /private/var/db/ConfigurationProfiles tmp ditto: /Users/alice/Security/Admin/Apple/APFS/tmp/Settings: Operation not permitted ditto: /Users/alice/Security/Admin/Apple/APFS/tmp/Store: Operation not permitted # ls -@delO tmp/Store drwx------ 5 root wheel - 160 Aug 8 13:55 tmp/Store                            * # The extended attribute on copied directory Store is empty, the file flags are missing, not preserved as documented and as usual behaviour of ditto was since a long time ( macOS 10.5 ). cp, rsync, tar, cpio exhibit the same misbehaviour. But I was using ditto to be sure to avoid any incompatibility with the Apple FS propriaitary modifications. As a consequence, all backup scripts and applications are failing more or less silently, and provide corrupted copies of files or directories. ( I was here investigating why one of my security backup shell script was making corrupted backups, and only on macOS ). How to recover the standard behaviour --extattr working on modern macOS?

I’m currently developing an iOS app built in Unity, exported to Xcode for signing and deployment. The app needs to register for Apple Push Notifications (APNs) to retrieve the device token and register it with a backend service (PlayFab). Despite enabling the required capabilities and entitlements, the app never receives a device token — the authorization request succeeds, but the token remains empty (req.DeviceToken is null in Unity). I’ve confirmed that the issue occurs before PlayFab or Firebase are involved, meaning the app never receives the token from Apple Push Notification service (APNs) itself. The Unity script I am using is: #if UNITY_IOS using UnityEngine; using Unity.Notifications.iOS; using PlayFab; using PlayFab.ClientModels; using System.Collections; using System; public class iOSPushInit : MonoBehaviour { private const int MaxRetries = 5; private const float RetryDelay = 2f; // seconds void Start() { Debug.Log("🛠 iOSPushInitDebug starting..."); StartCoroutine(RequestAuthorizationAndRegister()); } private IEnumerator RequestAuthorizationAndRegister() { // Request Alert + Badge + Sound permissions and register for remote notifications var authOptions = AuthorizationOption.Alert | AuthorizationOption.Badge | AuthorizationOption.Sound; using (var req = new AuthorizationRequest(authOptions, true)) { Debug.Log("⏳ Waiting for user authorization..."); while (!req.IsFinished) { yield return null; } Debug.Log($"🔔 Authorization finished at {DateTime.Now}: granted={req.Granted}, error={req.Error}"); if (!req.Granted) { Debug.LogError("❌ User denied notification permissions! Cannot get APNs token."); yield break; } // Authorization granted → check for device token int attempt = 0; string token = req.DeviceToken; Debug.Log($"req.DeviceToken: {req.DeviceToken}"); while (string.IsNullOrEmpty(token) && attempt < MaxRetries) { attempt++; Debug.Log($"ℹ️ APNs token not available yet. Attempt {attempt}/{MaxRetries}. Waiting {RetryDelay} seconds..."); yield return new WaitForSeconds(RetryDelay); token = req.DeviceToken; } if (string.IsNullOrEmpty(token)) { Debug.LogWarning("⚠️ APNs token still null after multiple attempts. Try again on next app launch."); yield break; } Debug.Log($"📱 APNs Token acquired at {DateTime.Now}: {token}"); // Register with PlayFab var request = new RegisterForIOSPushNotificationRequest { DeviceToken = token, SendPushNotificationConfirmation = false }; PlayFabClientAPI.RegisterForIOSPushNotification(request, result => Debug.Log("✅ APNs token successfully registered with PlayFab."), error => Debug.LogError("❌ Failed to register APNs token with PlayFab: " + error.GenerateErrorReport())); } } } #endif When running on a real device (not simulator), the following is logged in Xcode: 🔔 Authorization finished: granted=True, error= ℹ️ APNs token not yet available. Try again on next app launch. In the Xcode console, I do not see the expected APNs registration message: [Device] Registered for remote notifications with token: <...> Environment Details: Engine: Unity 6000.2.6f2 Notifications package: com.unity.mobile.notifications 2.4.2 Xcode: 16.4 (16F6) iOS Device: iPhone 12, iOS 26.0.1 Testing Method: Building directly from Unity → Xcode → real device Signing mode: Automatic (with correct Team selected) Certificates in account: Apple Development certificate (active) Apple Distribution certificate (active) Provisioning Profile: Type: App Store (also tested Development profile) Enabled Capabilities: Push Notifications, In-App Purchase App ID Capabilities: Push Notifications: Enabled Development SSL certificate: Present Production SSL certificate: Not generated (yet) Background Modes -> remote notifications What I Have Verified: ✅ Push Notifications capability is enabled in the Xcode target (not UnityFramework). ✅ Team and Bundle Identifier match my Apple Developer App ID. ✅ App ID has Push Notifications enabled in the Developer Portal. ✅ Tested on a real iOS device with working internet. ✅ Rebuilt and reinstalled app after enabling Push Notifications. ✅ Authorization dialog appears and permission is granted by user. How can I resolve this issue?

I am developing an app in Swift Playground (No Xcode). All my Views respond to the navigation call when I click NEXT except one. When I click NEXT the app hangs then crashes. The error message does not identify the cause of the crash. I have research every possible lead with no success. I would like to get some ideas on how to resolve this issue.

I have published a number of games under my account so far (before I let my account expire and 2 since I reactivated it) but now that I want to update my latest app I am told I can't submit it for review because my tax information is not up to date Looking at the missing info I see they want my VAT ID. That is the only thing missing on my account. Problem is that I am not a company and thus don't have a VAT ID. Now what? Does this mean I can never publish or update any app on iStore ever again until I change over to a business account and somehow make R50,000 outside of the App Store??? I am honestly stumped and don't know what to do :( Here in South Africa you are required to get a VAT ID if you earned over R1,000,000 in 12 months but you are allowed to voluntarily apply for a VAT ID once you earned over R50,000 for the year. In both cases, though, you have to be a company to apply. Individuals have to use their Tax Reference Number in place of a VAT ID whenever a VAT ID is required. So I try to use my TRN with App Store Connect and it just says my TRN is not valid. I copy paste it directly from the South African Revenue Services website to App Store Connect so it is absolutely correct and yet, Apple is saying "Nope, we don't like that number. Choose another one". So what do I do? 🤷

Dear Apple： I find a problem on Airpods Pro2（USB-C type）. 1、When an iPhone Xs Max running iOS 18.1 is connected to AirPods Pro 2 (Lightning connector version), the headphone settings page displays four noise cancellation modes: Off, Transparency, Adaptive, and Noise Cancellation. 2、When an iPhone 14 running iOS 26.2 is connected to AirPods Pro 2 (Lightning connector version), the headphone settings page displays three noise cancellation modes: Transparency, Adaptive, and Noise Cancellation How many modes is on Airpods Pro2？

Hi everyone — I’m hoping to get a quick technical sanity check from folks familiar with Apple’s satellite features. I’ve put together a very narrowly scoped request around the temporary enablement of existing iPhone satellite capabilities (Emergency SOS / Messages via Satellite), focused on a simple “check-in” use case. The idea is intentionally minimal: preset status messages only (e.g. “I’m safe”, “I need help”) optional one-time location sharing strict rate limits temporary enablement with a clear sunset date This isn’t a request for new features, internet access, voice, or emergency-service integration — it’s framed as a configuration/policy enablement using systems Apple already operates. I’ve documented the full scope and assumptions here Posting mainly to invite technical review, correction, or perspective from anyone familiar with how the satellite stack is structured today. Appreciate any insights.

Hi, Anyone else hitting this App Store Connect issue? I have now submitted two app versions. Both get accepted and I can release them, but the subscriptions are never included. What is happening: App versions get approved normally No “In-App Purchases” section appears on the app version review page Subscriptions page shows subscriptions stuck on “In Review” for 10 days Subscription localization is “Rejected” and completely locked I cannot edit, recreate, or resubmit anything related to subscriptions.. Tried submitting a new app version again, same result. App approved, subscriptions still stuck. So I keep releasing without subscriptions every time 🤦‍♂️ Anyone experienced this or found a way to unblock subscriptions when localization is rejected and locked? Thanks!

I created an application extension that uses IdentityLookup framework for SMS filtering. How can I deploy my product as a library? I tried wrapping it as a framework, but it was not successful.

I don't understand why elevation data is not stored in the sample using a standard length unit. Why is it stored in HKQuantityTypeIdentifier.flightsClimbed (which is 10 feet)? Surely it is not a memory usage issue. Treadmill GATT provides elevation in meters. Using HKMetadataKeyElevationAscended for the total elevation gain throws away a lot of data. Why is there no support for weighted vest or backpack? Changing body weight is not the same and provides incorrect energy. Users want to compare workouts with different weights. I don't see any metadata key for carried weight.

I'm using StoreKit 2 with Product.products(for:) to fetch my auto-renewable subscriptions. It works in the Xcode simulator with a local StoreKit configuration file, but returns an empty array (no error) in TestFlight. iOS 15+, using async/await API Products are configured in App Store Connect Paid Apps agreement is active Sandbox tester account set up Has anyone experienced this? What am I missing?

SKStorefront.countryCode always returns "US" in TestFlight and sandbox, even when sandbox Apple ID is set to a different country. Is this expected behavior? Is SKStorefront guaranteed to return the correct storefront only for production App Store builds?

Have had issues all day with the delayed Processing times as seen by other posts on this forum. But after my app has completed Processing (took 4 hours, usually takes 10 minutes), the build doesn't show up for Internal Tester. Internal tester usually gets all app updates, but when I try to add Group to build, the internal tester group is greyed out. If I try to add individual tester to build I get "An error has occurred. Try again later."

I've ran into an error with the insertRouteData function of the HKWorkoutRouteBuilder that I can't seem to find any information on. The error is "Unable to find location series 1A193D3B-AFF5-41D8-A967-B1BE08D9F543 during data insert.". It seems to only happen when trying to insert very long routes, in the most recent case it was a 5 hour bike ride with 5900 samples. I save all the route data in a sqlite table as backup and after checking out the data there isn't any red flags as to why it would not insert correctly. Has anyone seen this before and could offer some insight or point me in the right direction to find the source of the error?

hello apple through this message i want to draw you attention to some problems with gptk and rosetta some games like marvel spiderman 2 have broken animations and t pose issues and other like uncharted and the last of us have severe memory leak issues so its my request please fix it asap

I’m having an issue installing my TestFlight build on a Mac. The build (v1.0 build 1) uploads successfully and shows as “Complete” in App Store Connect. I can also open the build details page, and my Apple ID / tester access / group setup looks correct. However, on TestFlight (macOS), when I tap Install/Load, I get this error: Unable to install. The requested app isn’t available or can’t be found. Notes: The app is an iOS app (iPhone + iPad), and I enabled availability for Mac (Designed for iPad) in App Store Connect. The Mac is Apple Silicon, running macOS Tahoe 26.1. Could you help me understand why TestFlight shows this message on Mac, and what I should change in Xcode/App Store Connect to make the build compatible?

I develop a tab manager extension: https://apps.apple.com/ua/app/tab-finder-for-safari/id6741719894 It's written purely in Swift. All Safari interactions are done solely inside a SFSafariExtensionHandler . But now i'm considering adding some features from Google Chrome's Extension API like window switching. Is it possible to add a background.js worker to my existing Safari App Extension to have access to the beginRequest method override inside SFSafariExtensionHandler? Without converting my extension from Safari App Extension to Safari Web Extenion?
