Overview

Hi everyone, I am developing a benchmarking tool to measure memory latency (L1/L2/DRAM) on Apple Silicon. I am currently using Xcode Instruments (CPU Counters) to validate my results. In my latest run for a 128 MB buffer with random access, Instruments shows: Latency (cycles): ~259 cycles (derived from LDST_UNIT_OLD_L1D_CACHE_MISS / L1D_CACHE_MISS_LD). Manual Timer Result: ~80 ns. To correlate these two values, I need the exact CPU Frequency (GHz) at the time of the sample. My Questions: Is there a recommended way to programmatically fetch the current frequency of the Performance cores (p-cores) during a benchmark run? Does Apple provide a "nominal" frequency value for M-series chips that we should use for cycle-to-nanosecond conversions? In Instruments, is there a hidden counter or "Average Frequency" metric that I can enable to avoid manual math? Hardware/Software Environment: Tool: Instruments 26.3+ (CPU Counters Template). Chip: A19, iPhone 17 pro. OS: 26.3.

'Guideline 2.1 - Performance - App Completeness' - "...could not be found in the submitted binary." I have checked with internal and external testers and my devices and simulators, everyone sees the in app purchases but I just had my submitted rejected for the second time with the comment that these in-app none-consumable purchases cannot be found with the submitted binary. I even attached a slow step by step screen recording for the review reply after the first rejection showing how to reach the purchasable packs by navigating through only 3 buttons: "How to access the purchase flow: Launch the app Tap the bottom-center Settings button (icon: switch.2) Tap “Customisation gallery” Scroll to find any pack listed above Tap the pack price chip Tap “Buy pack – [price]” to start the StoreKit purchase flow" I also attached a clear image along with detailed instruction (same as above) for the Review Information. and the second rejection was received today for the same reason. I'm being guided to the localization 'Developer Action Needed'. I'm not sure what more can be done? I feel like my review replies aren't even looked at.

We’ve been implementing LiveCallerId using OHTTP and have hit a wall with the production environment. The setup works perfectly in TestFlight, but the release version of the app is consistently being rejected by the Apple OHTTP Relay when trying to tunnel traffic to our gateway. Timeline & Status: Applied via the form in September 2025. Received confirmation in November 2025 that our /.well-known/ohttp-keys endpoint was correctly configured. Since then, we've struggled to get a dialogue with Apple to confirm the final production whitelisting. Technical Observations: Our ohttp-keys endpoint is being polled frequently (every few minutes). Based on the traffic, this is clearly the Apple Relay infrastructure fetching/refreshing the keys, not the devices themselves. This suggests the Relay "sees" our configuration, yet it still refuses to tunnel traffic to our gateway in the production environment. Since everything is functional in TestFlight, our implementation seems correct. It feels like there is a configuration mismatch or a missing "production flip" on the Relay side for our Bundle ID. If anyone from the Apple engineering team could verify the status for this Bundle ID, it would be a huge help. We've been stuck in this "TestFlight-only" state for quite a while now.

Hello, I'm trying to enroll in the Apple Developer Program but I'm running into an ID verification issue. I'm in Canada and my ids are Canadian but I think my apple account still thinks my region is France (I changed back to Canada a few months ago and it shows Canada in Settings) since I had set it to France for when I was there. Also my phone number is still French. On Mac: my Canadian passport and Canadian driver's license are rejected as not valid for my region. On iPhone: the app just tells me to contact support. I've already reached out to Apple Developer Support but I have had no response for a few days. Is there a fix for this? I have already tried uninstalling and reinstalling the developer app.

Hi everyone, I’m encountering a persistent issue with a visionOS app distributed through TestFlight for internal testing. The Problem: I have successfully archived and distributed the build as an Internal Test. The testers (including myself) received the invitation, accepted it, and the app is visible in the TestFlight app on Apple Vision Pro. However, the moment we click the "Install" button, an alert pops up saying: "The requested app is not available or doesn't exist." Context: Platform: visionOS (Targeting Vision Pro). App History: This is an ongoing project where the last distribution was about 5 months ago. The app has never been submitted for formal App Review or public release; it has only been used for TestFlight. Account Status: All agreements (including the Paid Applications Agreement) are active and in effect. What I have tried (but did not work): Re-uploading builds: Increased both version and build numbers and re-archived. Resetting Test Groups: Deleted the existing internal testing group, waited, and created a new group to re-invite testers. Tester Association: Removed all testers and re-added them to force a new invitation email. Device-side: Signed out and back into "Media & Purchases" on the Vision Pro. Key Observation: To determine if it was a project-level configuration error, I created a completely new App Identifier (Bundle ID) for the same project code and uploaded it as a new app record. In this case, TestFlight worked perfectly, and I could install the app without any issues. This leads me to believe that the original Bundle ID is stuck in some kind of "detached" or "stale" state on the App Store Connect backend. Has anyone experienced a specific Bundle ID being "corrupted" in the TestFlight system after a period of inactivity? Is there a way to force a full reset of the TestFlight status for an existing app record, or is this a backend bug that only Apple Support can resolve? Any insights or workarounds would be greatly appreciated.

We are developing a platform (Ferve) where users subscribe to individual artists to access exclusive content. We use a user-centric remuneration model: each artist has an independent income pool, and funds from a specific subscription must be attributed solely to that artist. We have two critical challenges regarding our integration: Granular Financial Reporting for User-Centric Payouts As the Merchant of Record, Apple provides aggregate Financial Reports. However, these reports do not provide a breakdown of taxes, commissions, or exact exchange rates used for individual transactionId records. Though we can keep records of each transaction in our database, thus linking them with which artist they belong to, we are unable to collect fees/taxes applied to each individual transaction. Because our payouts are artist-specific, we need to deduct the exact regional taxes and Apple commissions from each transaction to calculate the artist's due balance. Currently, we can only see the final consolidated balance in BRL (Brazilian Reals) at the end of the month. Is there an API or report that provides the net proceeds and tax breakdown per transaction ID? How can we retrieve the exact exchange rate applied to foreign currency sales (e.g., EUR to BRL) before the final consolidation? Supporting Multiple Concurrent Subscriptions Our current App Store Connect configuration uses a single 'Subscription Group' for all artist 'Clubs' since they share the same price points. However, we have found that users cannot subscribe to more than one product within the same group simultaneously (the App Store treats this as an upgrade/downgrade). On our platform, a user must be able to subscribe to Artist A and Artist B at the same time. What is the recommended architecture for this? Should we dynamically create a unique Subscription Group for every artist onboarded to our platform? If we use unique groups, is there a limit to the number of Subscription Groups one app can have? We appreciate the help, Ferve

Dear All, I am writing to report what appears to be a bug in the Apple Developer App’s enrollment verification system that is incorrectly flagging personal hardware. Problem Statement: I am unable to complete enrollment for the Apple Developer Program. On the "Personal Information" or "Identity Verification" stage, the app displays: "Contact Us to Continue. There may be an issue with your account that needs to be resolved..." Hardware History: Device: iPhone 14 (iOS latest) The device was previously owned by a family member who never enrolled in the Developer Program. The device was factory reset/wiped before my account was added. Despite this, Support (Case 102822291300) states the device is flagged as a "shared device" and refuses to proceed with identity verification. The Impasse: Support has indicated they cannot provide further assistance. However, as an individual developer, this is my primary device. If the system is flagging a reset device as "shared" when there is no history of developer use, it suggests a flaw in the automated verification logic. Request: Can a moderator or support representative look into Case 102822291300 to verify why this specific hardware is being restricted? Is there a manual path for identity verification (Passport/National ID) that doesn't rely on the Apple Developer App's automated device check? Allow me to do manual verification and provide the resolution to the issue. I am eager to bring my app to the platform and would appreciate a path to resolution. Kind Regards, Pradeep Bangalore

While WhatToTest..txt was being used in xcode cloud. I wish this feature should just being adopted to functioned from XCode archive and upload to set initial release note from the build pipeline directly from xcode in machine

Is there an issue with Apple Developer expediting a submission, also I am unable to reach out to support without an error. The error is just a generic "ERROR" I cannot access developer support to reach out and describe the issue. This is everyone inside my organization using both a corporate network and personal network. This has been going on for over a month

Hi everyone, We are facing a critical blocker with our macOS app processing. Since March 5, 2026, every single build we have uploaded (8 builds total) has been stuck in the "Processing" state for over 4 days. For our project, due to the large binary size, processing usually takes about 4 to 6 hours normally. However, we now have a long queue of builds that haven't transitioned to "Ready to Submit" for up to 80+ hours. Stuck Builds List: 1.0.0 (444): Mar 8, 3:09 PM (Processing) 1.0.0 (443): Mar 8, 5:36 AM (Processing) 1.0.0 (440): Mar 7, 6:37 AM (Processing) 1.0.0 (438): Mar 6, 5:01 PM (Processing) 1.0.0 (434): Mar 6, 12:04 AM (Processing) 1.0.0 (433): Mar 5, 6:26 PM (Processing) 1.0.0 (432): Mar 5, 10:51 AM (Processing) 1.0.0 (431): Mar 5, 6:11 AM (Processing) (Note: The last successful build was 1.0.0 (429) on March 4, which processed within the expected 6-hour window.) There have been no changes to our project settings, Info.plist, or entitlements since the last successful build. This is completely halting our scheduled update release. Is anyone else experiencing a similar backlog with large macOS binaries? Or is there a known issue with the App Store Connect pipeline for the macOS platform recently? Any help or investigation from Apple engineers would be greatly appreciated. (Feedback ID: FB22156358)

Will I be able to download and run Xcode 26.3 on a new MacBook Air with an M5 chip? If yes, what memory size is recommended? 16, 24 or 32 GB ?

I'm new to graphics and game design and I just wanted to know if a compute pipeline could be as efficient as a render pipeline for rasterization and an explanation on how and why. Also is it possible to manually perform rasterization with a render pipeline as in manipulate individual pixel data in a metal texture yourself but do it with a render pipeline?

I want to enroll into the Apple developer program but it keep showing me: Your enrollment could not be completed. Your enrollment in the Apple Developer Program could not be completed at this time. I am from iraq I contacted the support but they did not give me any solution

I have opened a developer account couple of month ago, and enrolled successfully. Did the app store connect and put the app for testing. The company decided to change legal entity, and thus, I had to create a new developer account. So, I have enrolled to a new developer account. My enrollment is pending for almost 3 weeks, while I do not understand what is the status. I have tried sending emails to support and also calling support, but no success. What can I do?

Hello Apple Developer Community, I'm experiencing an invalid_client error (HTTP 400) when attempting to authenticate with the Apple School Manager API using OAuth2 with JWT bearer assertion (RFC 7523). Despite verifying all configuration values and following Apple's documentation, I continue to receive this error.

Previous Support Interaction I've contacted Apple Developer Support (Case #102783504559). They confirmed: The technical implementation is correct The issue is an account access/permission problem My Apple Account email is not associated with any memberships The Account Holder must add me to the Enterprise team membership However, I'm posting here to see if anyone in the community has: Experienced similar issues and found a solution Additional technical insights about the invalid_client error Suggestions for what else to verify or try Questions Is there a specific format requirement for the sub claim? Should it be the Client ID (Service ID) or Organization ID? I've tried both. Are there any additional claims required in the JWT beyond iss, sub, aud, iat, exp? Could there be a backend issue with the API account even though it appears active in Apple School Manager? Has anyone successfully resolved an invalid_client error that wasn't related to account access? Is there a delay after creating an API account before it becomes fully active for authentication? Technical Details Language: Python (Flask) JWT Library: PyJWT with cryptography library Algorithm: ES256 (ECDSA P-256) OAuth2 Flow: Client Credentials Grant with JWT Bearer Assertion (RFC 7523) Error Log I've generated a detailed error log showing the exact request/response. The key points: HTTP 400 Bad Request Response: {"error":"invalid_client"} Same error occurs with both Client ID and Organization ID as sub Any Help Appreciated If anyone has encountered this issue or has insights into what might be causing it, I'd greatly appreciate your help. I'm happy to provide additional details or try any suggestions. Thank you!

Hi App Review Team. I understand that there are many apps from developers to review, I understand april required changes, but please, my apps are stucked in Waiting for review status too long (App ID: 6758546705, App ID: 6756194410, App ID: 6758354010), We have deadlines that we are already not met, we need to have apps in store asap. So please help. I've already posted such kind of post here and you answered that team is investigating the issue, but there is no any contact and any info. Please help, we are breaching our deadlines. Thank you

I currently have my own individual App Store Connect and Apple Developer distributor account registered with the email address m*******@*mail.com. For one of my clients, we also created a separate individual App Store Connect and Apple Developer account. I added my account as an Admin to the client’s account. On the App Store Connect side, I can perform all operations without any issues, such as managing the app, handling TestFlight, and submitting new versions. However, when I access the Apple Developer portal, I cannot see or manage the accounts I am responsible for. For example, I cannot view information such as the Team ID, certificates, provisioning profiles, or other developer settings. To work around this issue, I created a new Apple Developer membership using a different email address. However, when I logged in with that account, I was still unable to view the Team ID or other developer-related settings. My question is: Has the system always worked this way, where App Store Connect and Apple Developer access are managed separately? Or could this be an unnoticed authorization or configuration issue? I would appreciate your clarification on this matter.

Users report being able to log-in on the website and everywhere else, using google sign-in credentials, just not working on the app.

I have been experiencing many issues trying to integrate the Apple AlarmKit in my app. I essentially keeping getting authorization errors. I was wondering if anyone else was experiencing issues like this and if anyone had guidance or a fix for what I am experiencing. I was under the impression that any devices IOS26+ could use the AlarmKit but maybe I am mistaken. Getting (com.apple.AlarmKit.Alarm error 1.) every time I try and enable alarms.

İ will pay but i wait a lot of time ((
