After updating my system to macOS Tahoe 26.1 and Xcode 26.1, all breakpoints in my project fail to work. When I run the application in Debug mode, any enabled breakpoint (blue) immediately becomes disabled (grayed out) the moment the app launches. The application runs, but the debugger never stops. This issue occurs in any location, including in the application's init() method, which should always be hit. This behavior suggests that the LLDB debugger is failing to attach to the process at launch or is being instructed not to enable breakpoints. System Configuration: Mac Model: MacBook Pro 14 (2021), Apple M1 Pro macOS Version: Tahoe 26.1 Xcode Version: 26.1 Project Type: SwiftUI App for macOS Troubleshooting Steps Performed (All Unsuccessful): We have performed an extensive series of troubleshooting steps to resolve the issue, none of which have worked. These steps include: Basic Project Cleaning: Cleaned the build folder (Product > Clean Build Folder). Deleted the entire DerivedData directory. De

Issue: Background downloads using the flutter_downloader package work perfectly in debug mode and release mode when run directly from Xcode (plugged in). However, when I create an archive build and install the app separately (via TestFlight or direct IPA install), the background download stops working as soon as the app is minimized. ✅ What I’ve already done Info.plist UIBackgroundModes remote-notification fetch processing audio push-to-talk AppDelegate.swift import UIKit import Flutter import Firebase import flutter_downloader import BackgroundTasks @main @objc class AppDelegate: FlutterAppDelegate { static let backgroundChannel = com.example.app/background_service private var backgroundCompletionHandler: (() -> Void)? override func application( _ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? ) -> Bool { FirebaseApp.configure() GeneratedPluginRegistrant.register(with: self) FlutterDownloaderPlugin.setPluginRegistrantCallback(r
Hi everyone, We're experiencing a critical and persistent code signing failure (HTTP 403) after accepting the latest Apple Developer Agreement, blocking our application release. Problem: Despite confirming the new Apple Developer Agreement is signed and active on the portal, code signing attempts return an HTTP 403 error, stating a required agreement is missing or has expired. Steps Taken: Accepted new Apple Developer Agreement. Verified active developer membership and valid certificates (good for years). Cleared caches, restarted systems. Confirmed Team ID, Apple ID, and provisioning profile validity. Any help is greatly appreciated, its been stuck for more than 2 days now.

When following the official SwiftUI Tutorial Landmarks, I should be able to Cmd-Ctrl-Click an element of a preview in Selectable mode to view a list of options. But Xcode shows only one option (Embed). Furthermore, if I try to type anything the popover breaks completely and grows in length infinitely. I am not sure whether this is a bug, or I missed something when installing Xcode, or both
After more than a year since the announcement, I'm still unable to get this feature working properly and wondering if there are known issues or missing implementation details. Current Setup: Device: iPhone 16 Pro Max iOS: 26 beta 3 Development: Tested on both Xcode 16 and Xcode 26 Implementation: Following the official documentation examples The Problem: Semantic search simply doesn't work. Lexical search functions normally, but enabling semantic search produces identical results to having it disabled. It's as if the feature isn't actually processing. Error Output (Xcode 26): [QPNLU][qid=5] Error Domain=com.apple.SpotlightEmbedding.EmbeddingModelError Code=-8007 Text embedding generation timeout (timeout=100ms) [CSUserQuery][qid=5] got a nil / empty embedding data dictionary [CSUserQuery][qid=5] semanticQuery failed to generate, using (false) In Xcode 16, there are no error messages at all - the semantic search just silently fails.

Below is the error when I tried to make build file for my application , so that I can add this build file in store connect for Review Xcode version 26.0.1 System version 26.0.1 .NET Version 9.0 (for application) application based on MAUI Hybrid Application Showing Recent Errors Only Prepare build error: Multiple commands produce '/Users/mayankjain/Library/Developer/Xcode/DerivedData/PCS_EmpApp-chsylqbxjptobeawzzckymqzagvr/Build/Products/Debug-iphonesimulator/PCS_EmpApp.app/Info.plist' note: Target 'PCS_EmpApp' (project 'PCS_EmpApp') has copy command from '/Users/mayankjain/Documents/05-NOV-2025-SWETA_IOS/PCS_EmpApp/PCS_EmpApp/xcode-out/Platforms/iOS/Info.plist' to '/Users/mayankjain/Library/Developer/Xcode/DerivedData/PCS_EmpApp-chsylqbxjptobeawzzckymqzagvr/Build/Products/Debug-iphonesimulator/PCS_EmpApp.app/Info.plist' note: Target 'PCS_EmpApp' (project 'PCS_EmpApp') has process command with output '/Users/mayankjain/Library/Developer/Xcode/DerivedData/PCS_EmpApp-chsylqbxjptobeawzzckymqzagv

Both processes try to put it in the same place, hence the 'multiple commands produce...' error. Remove that copy command, and the build should work.

We have also encountered a similar issue. Our product establishes a socket connection with an iPhone after connecting via Wi-Fi. However, recently, a large number of users with iPhone 17 series devices have reported that their iPhone 17 series products cannot communicate normally with our product. The specific symptom is that the socket connection fails due to timeout.

@ieung Thanks for checking in! :wave: You can create your project in Xcode 26, Swift Playgrounds 4.6 or later, but for the final submission, it should be packaged as an app playground (.swiftpm) in a ZIP file. This format ensures it can run offline and meet the review requirements. You can find all the details on the Eligibility and Requirements page for future reference. Happy to help if you have more questions!

Hello, I'm suddenly encountering errors with In-App Purchases (IAP) and my sandbox webhooks, which were working correctly just a few days ago. Specifically: Product Information Error: I'm receiving the following error when trying to fetch product information: { type: product_info, result: error, error: An unknown error occurred } This API call was functioning normally until today. Sandbox Webhook Failure: I have configured a sandbox webhook, but my server is not receiving any notifications from the App Store. Test API 401: When I attempt to call the test API (https://api.storekit-sandbox.itunes.apple.com/inApps/v1/notifications/test), I consistently receive a 401 (Unauthorized) error. Could you please provide some guidance on how to troubleshoot these issues? Thank you.
Did you find a solution to this? I am new to app development. I am trying to make an app that will assist in making proper videos and screenshots for submission to the App Store. They images must be a certain size, it isnt easy to just drag a window to be 1200x400, and not 1201x399 for example. I want a simple menu item, that will resize a window to a preset size. It works using AX with no sandbox... I would love to sell the app on the App Store, although my primary motivation is to try to improve sales of my other app on the MacOS App Store. My App which I am very proud of, has sold 1 copy since going live on the App Store... I am not expecting Massive sales volume, as it is a niche product. I know people in my true industry (I am not an app developer) would love the app if they got a ahold of it.... I won't self promote it here, as it isnt the place, and either way it is unlikely someone reading this thread would have a use for that app... I think app developers may find this other app, with the sa

Dear App Review & App Store policy team, I am writing as an independent macOS developer who has spent more than the last six months building TilesWM, a full‑featured window‑manager that rivals existing products such as Magnet, Divvy and BetterSnapTool. The app works exactly like those solutions: it uses the Accessibility (AX) API to move and resize arbitrary windows, registers global hot‑keys, and stores user preferences locally in ~/Library/Application Support/. When I attempt to submit TilesWM through App Store Connect the validation process failed with two errors, one of which was relatively easily solvable with the help of ssmith_c and Quinn. The other, the hard blocker: Sandbox not enabled – the app does not contain the required com.apple.security.app-sandbox = true entitlement. but: The same accessibility entitlement is absent from the binaries of Magnet, Divvy, BetterSnapTool and other window‑manager apps that are already available on the Mac App Store. Those applications were on the Store

Thank you for this response. I believe I now understand what was happening but still don't fully understand why it suddenly started happening. Ultimately what's happening is that the packaged build from Unreal (which is then also built through XCode) is not packaging the cacerts with it. I don't think it previously did either, but I wonder if my built app is now being sandboxed and no longer has access to the devices root certs? The solution was essentially to ensure that a cacert.pem file (with the latest root certs) is packaged with my app so it could access that to verify my servers certs. I can also see that root certificates got updated since Nov 4th here: https://curl.se/docs/caextract.html (which is the same day I made this post, coincidence?) - I am thinking this might have something to do with why I am suddenly seeing this issue. If there is no sandboxing and my app has access to my devices certs, then maybe my device did not get the latest certs update (but my websocket se

Hello everyone, We are migrating our KEXT for a Thunderbolt storage device to a DEXT based on IOUserSCSIParallelInterfaceController. We've run into a fundamental issue where the driver's behavior splits based on the I/O source: high-level I/O from the file system (e.g., Finder, cp) is mostly functional (with a minor ls -al sorting issue for Traditional Chinese filenames), while low-level I/O directly to the block device (e.g., diskutil) fails or acts unreliably. Basic read/write with dd appears to be mostly functional. We suspect that our DEXT is failing to correctly register its full device personality with the I/O Kit framework, unlike its KEXT counterpart. As a result, low-level I/O requests with special attributes (like cache synchronization) sent by diskutil are not being handled correctly by the IOUserSCSIParallelInterfaceController framework of our DEXT. Actions Performed & Relevant Logs 1. Discrepancy: diskutil info Shows Different Device Identities for DEXT vs. KEXT For the exact same hardware, t
Hi everyone, I'm developing an iOS app using Foundation Models and I've hit a critical limitation that I believe affects many developers and millions of users. The Issue Foundation Models requires the device system language to be one of the supported languages. If a user has their device set to an unsupported language (Catalan, Dutch, Swedish, Polish, Danish, Norwegian, Finnish, Czech, Hungarian, Greek, Romanian, and many others), SystemLanguageModel.isSupported returns false and the framework is completely unavailable. Why This Is Problematic Scenario: A Catalan user has their iPhone in Catalan (native language). They want to use an AI chat app in Spanish or English (languages they speak fluently). Current situation: ❌ Foundation Models: Completely unavailable ✅ OpenAI GPT-4: Works perfectly ✅ Anthropic Claude: Works perfectly ✅ Any cloud-based AI: Works perfectly The user must choose between: Keep device in Catalan → Cannot use Foundation Models at all Change entire device to Spanish → Can use Foundation Mo
