I posted about this about 5 years ago, and now at last it's close to being finished. The main problem that I now have is related to matching up DWARF debuginfo and global variables. This works fairly well on macOS 10.14. On 10.15 much less so, and I think that the reason is how the macho data is mmap'd. When Valgrind runs it does the job of the OS and loads the guest exe into memory. It'll then load and run dyld in Valgrind. I can get memory map debug traces. In one test with a problem I see 4 load segments. __DATA_CONST and __DATA both have prot 3 (RW) so we load them RW and not R then RW. Then I think that dyld munmaps and re mmaps the _DATA_CONST segment as RO. Valgrind works based on mmaps triggering reading debuginfo. I don't think that it handles munmap correctly. I need to debug that a lot more - I can see the changed mappings in the debug output but I don't see exactly what is happening with munmap and mmap (unless dyld is doing that on a section by basis). Does what I'm saying about the mappings make any sense?

Hi! I would like to experiment with the Accessory Setup Kit, but I am not sure how I can add the required entitlement to my Apple Developer account. I added the following to the plist file: NSAccessorySetupKitSupports WiFi NSAccessorySetupWiFiSSIDPrefix test_ test And the following to the entitlements file: com.apple.developer.accessory-setup-kit But I am unable to build as my provisioning profile doesn't include "com.apple.developer.accessory-setup-kit entitlement". On the developer portal, I navigated to “Certificates, Identifiers & Profiles” > “Identifiers” > “”, but I don't see it under "Capabilities" or "App services", nor under requests. How do I configure my profile so that I am able to make use of this kit?

My app start up has became horrid. It takes 1 minute to open SQLlite database for my rust core. Impossible to work... I have Address Sanitizer, Thread Perf Checker and Thread Sanitizer disabled...

Hi everyone. I'm trying to use https://developer.apple.com/documentation/appstoreserverapi/get-transaction-info to retrieve order information. How can I get the refund status of an order through this API? Also, Apple's webhook notification for refunds includes fields like revocationReason and revocationType. Can these be retrieved through the API? I've noticed that some refund orders have these fields when retrieved using get-transaction-info api, but others don't. I don't know the reason for these differences. Could you please explain? Thank you very much.

Xcode 26.2 RC has been out for over 24 hours and it's still not possible to submit apps.

Hi, Problem When playing videos on the Developer app on the Mac, there is no full screen button for the video. So it is not possible to play the video in full screen. Note I am not referring to the app going into full screen, the issue is with there is no option to play the video in full screen. Environment OS: macOS 26.2 (25C56) Developer app: Version 10.8.3 (1083.3.1) Feedback FB21343934 Recording Question Are others also facing this issue? Is there a workaround? Suggestion This seems to be recurring problem that seems get broken with app / OS releases. Please write some UI tests to ensure the full screen button is present. Would really appreciate if this gets fixed.

Has anyone been able to use Google Gemini with Intelligence in Xcode? I got the Claude models working in there but as much as I try I can't see any Gemini models.

Hey all, I recently updated to Xcode 26.2 and I'm having the hardest time trying to download the corresponding iOS simulator. I installed Xcode from developer downloads and the app did not come loaded with an iOS simulator. When trying to download from Components in Settings, I only get the following message: Download failed due to a bad URL. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) Domain: com.apple.MobileAssetError.Download Code: 49 User Info: { checkConfiguration = 1; } I also tried downloading via Terminal but also get a download failed message. I am on the latest macOS and have over 600 GB of disk space available. In previous versions, I was able to download the iOS simulator directly from Developer Downloads, but anything after 26 is not there. Any suggestions?

Instruments is crashing when the swiftui instrument is stopped (the session is finished) and the transfer begins from device to device: Crashed Thread: 11 Dispatch queue: com.apple.swiftuitracingsupport.reading Exception Type: EXC_BAD_INSTRUCTION (SIGILL) Exception Codes: 0x0000000000000001, 0x0000000000000000 Termination Reason: Namespace SIGNAL, Code 4 Illegal instruction: 4 Terminating Process: exc handler [1633] I've tried removing derived data, reinstalling xcode, updating xcode (I originally thought this might be the issue -- I needed to update to 26.2 from the 26 RC -- the update didn't fix crash or change the crash report), and restarting both devices. I'm running Instruments/Xcode 26.2 on a MacBook Pro 15" (2018) running Mac OS 15.7.2 (24G325) with an iPhone 16 Pro Max running 26.2. Hoping someone else might have seen this or could help me troubleshoot. I find the swiftui instrument be helpful and like to use it :) I can post a complete crash report as well.

Gitlab runner on M4 Mac Mini 2024, XCode 26.2, supported platforms: iOS, native UIKit swift project. Cocoapods. Trying to run tests via fastlane: run_tests(workspace: 'Project.xcworkspace', destination: "platform=macOS,id=#{deviceId}", scheme: "Release", clean: true) And having an error: $ xcodebuild -showBuildSettings -workspace Project.xcworkspace -scheme Release -destination platform\=macOS,id\=01234567-0123456789B9001C 2>&1 [12:23:53]: Could not read the "SUPPORTED_PLATFORMS" build setting, assuming that the project supports iOS only. [12:23:54]: Found simulator "iPhone 16 Pro (18.5)" The tests runs just fine in xcode on "My Mac (Designed for iPad)" device on the very same machine. Compared the output of xcodebuild -showdestinations in terminal: $ xcodebuild -showdestinations -workspace Project.xcworkspace -scheme Release Available destinations for the "Release" scheme: { platform:macOS, arch:arm64, variant:Designed for [iPad,iPhone], id:01234567-0123456789B9001C, name:My Mac } { platform:iOS, id:dvtdevice-DVTiPhonePlaceholder-iphoneos:placeholder, name:Any iOS Device } { platform:iOS Simulator, id:dvtdevice-DVTiOSDeviceSimulatorPlaceholder-iphonesimulator:placeholder, name:Any iOS Simulator Device } { platform:iOS Simulator, arch:arm64, id:A7E98A79-B29B-4E9A-8103-ECBA55ABC0C6, OS:26.2, name:iPhone 17 Pro } But when I launch this command in gitlab runner, I get this: Available destinations for the "Release" scheme: { platform:iOS, id:dvtdevice-DVTiPhonePlaceholder-iphoneos:placeholder, name:Any iOS Device } { platform:iOS Simulator, id:dvtdevice-DVTiOSDeviceSimulatorPlaceholder-iphonesimulator:placeholder, name:Any iOS Simulator Device } { platform:iOS Simulator, arch:arm64, id:A7E98A79-B29B-4E9A-8103-ECBA55ABC0C6, OS:26.2, name:iPhone 17 Pro } I suspect gitlab runner to ruin some ENV variable, probably. So I googled the most common issues on the internet and tried everything I found: LANG: "en_US.UTF-8" LC_ALL: "en_US.UTF-8" unset CFProcessPath And none is worked. I also compared the printenv output in terminal and gitlab runner, didn't found anything suspicious. Ran out of ideas. How can I troubleshoot this?

This is a screenshot from the Swift Task track in Xcode. I made these tasks with public actor ResourceManager { func foo() { for observer in observers { Task(name: "ResourceManager notify observers") { await notification(observer) } } } } I am confused why each of the task is showing as a separate task in the task lifetime summary. Is there a way to queue the trace in Instruments into the fact that these are indeed the same task?

Am developing an application that creates custom VPN. I have enabled Sandbox properties. VPN will be granted based upon the device posture. Posture includes reading the disk encryption value, secureboot and Firewall values. Application just tries to fetch the values to provides its posture. Since the application is sandboxed, it is getting denied to read the above mentioned values. How to achieve this with Sandboxed enabled?

Hi all, I'm new to TestFlight and Apple Store Connect. I have pushed a build and it says "waiting for review". Do I have to do anything to put it into review? I'm trying to get this build out to external testers.

I have been trying to get into my account for several days now and I have tried everything. First of you cannot get support because you need to be logged in so had to make another account to be able to post this. And even then the support is not working. Send an email a while ago and tried the call option and I have gotten no response from both. I was supposed to launch my app last week and I have just not be able to log into my account. I keep getting the 'Too many verification codes have been sent. Enter the last code you received or try again later.' I didn't even do that, I just tried to log in and had that there. I have waited days and it's still there. I have tried changing the number for which I waited a day and now it's told me to wait another 6 days. This has caused so many problem and the lack of support is unbelievable. Can anyone please help me get into my account or advise on what I can do ASAP. Thanks, Usama

The profile expiration date is approaching, and no amount of inquiries will solve it. Create a new profile Download a new profile from Xcode Press archive, press Distribute App, press Enterprise, and distribute Invalid expiration date in profile of summary of review app.ipa content I've tried everything that comes out by Googleing profiles, such as regenerating profiles, erasing caches, updating Xcode, updating macOS, deleting existing profile information, etc. Expiration date different from the expiration date of the profile created in that menu is displayed. The expiration date of the profile I created is December 8, 2026, and the previous certificate is January 22, 2026. However, the profile information of the generated ipa is February 12, 2026. So I can't distribute this app because I'm scared, and the expiration date is coming up. Users should have a period of time to update. Get me a novice developer who's choking up.

Hello, I am having a recurring issue using Swift Playgrounds version 4.6.4 on macOS 26.1. Upon opening a file and every other time I start typing in the code section I get a prompt, the image below, two or three times. It doesn't matter if I accept or decline all or some of the prompts, as soon as I start typing on another line I get prompted another two or three times for permission. It appears to me that prompt generates every time the preview pane tries to update. Declining the prompt breaks the preview but accepting the prompt only gets you through a single line of code before it appears again. I believe this issue started after I updated to macOS26.1 as I had not encountered it before. I've also opened other files with Swift Playgrounds and encounter the same problem. It could also be unrelated to the update and could be an issue with some permission setting somewhere, however, I have been unable to find what or where it could be. Is anyone else experiencing this? Thank you for your time :)

The Send to Device in Reality Composer Pro no longer works for me. The progress spinner keeps spinning... Happens with Wifi and Developer Strap (first gen). Any known workarounds / ways to recover?

We have developed an iPad application using the ARCL (AR + CoreLocation) library to render Point of Interest (POI) annotations in both an AR view and a standard MapView. The application performs as expected on standard devices. However, we have some iPad covered with strong magnet. This creates significant magnetic interference, resulting in a 90° to 180° heading offset, rendering the AR POI placement and MapView orientation unusable. Technical Challenges & Constraints: Hardware Lock: The magnetic cover is a mandatory business requirement and cannot be removed during field use. Sensor Failure: The internal magnetometer cannot provide an accurate North reference due to the proximity of the cover’s magnets. While CoreLocation and CoreMotion use sensor fusion, the magnetometer remains the primary source for absolute heading. Alternative Orientation Tracking: Is there a documented method to bypass the magnetometer and derive device orientation using only the Gyroscope and Accelerometer (e.g., relative tracking) while still maintaining alignment with geographic coordinates in CoreLocation? Programmatic Offsets: Are there known APIs or mathematical workarounds to programmatically "nullify" or offset a constant magnetic bias once the device is inside the cover? so we can use that offset for ARView and in Mapview as well.
