Overview

Hello Apple Developer Community, I'm seeing a persistent crash in my iOS app reported via Firebase Crashlytics. The issue only started appearing on devices running iOS 26.3.0 and above (the crash does not occur on lower iOS versions, and it's unrelated to my app's version number). Key points: My app does NOT use any Text-to-Speech (TTS) features whatsoever. No AVSpeechSynthesizer, no Speech framework, no related APIs called from our code. My app is primarily written in Objective-C (with some Swift components possibly via dependencies). The crash stack is entirely within Apple's private TextToSpeech framework, specifically in ausdk::BufferAllocator::instance(). I suspect it might be indirectly triggered by a third-party ad SDK (e.g., Google Mobile Ads, AppLovin, etc.) that could be loading or interacting with accessibility features in the background — but this is just a hypothesis, as I have no direct evidence yet. Here is one representative crash log: Crashed: com.apple.root.user-initiated-qos.cooperative 0 TextToSpeech 0x6bb00 ausdk::BufferAllocator::instance() + 99800 1 TextToSpeech 0xf8c60 ausdk::BufferAllocator::instance() + 677688 2 TextToSpeech 0xf8c60 ausdk::BufferAllocator::instance() + 677688 3 TextToSpeech 0x1a0b9c ausdk::BufferAllocator::instance() + 1365620 4 libswift_Concurrency.dylib 0x628b4 swift::runJobInEstablishedExecutorContext(swift::Job*) + 288 5 libswift_Concurrency.dylib 0x63d28 swift_job_runImpl(swift::Job*, swift::SerialExecutorRef) + 156 6 libdispatch.dylib 0x13f48 _dispatch_root_queue_drain + 364 7 libdispatch.dylib 0x146fc _dispatch_worker_thread2 + 180 8 libsystem_pthread.dylib 0x137c _pthread_wqthread + 232 9 libsystem_pthread.dylib 0x8c0 start_wqthread + 8 The crash occurs on a background cooperative queue (Swift Concurrency). Questions: Has anyone else seen crashes inside ausdk::BufferAllocator::instance() in TextToSpeech on iOS 26.3.0+ even without using TTS in their app? Could a third-party ad SDK be causing the TextToSpeech framework to load unexpectedly (e.g., via accessibility preloading)? Is this a known bug in iOS 26's Spoken Content / Speak Selection features? Any workarounds or fixes from Apple? Any insights, similar reports (especially from Objective-C based apps), or advice would be greatly appreciated! Thanks!

I've read several topics on cancelling subscriptions in sandbox environment, but it seems to me that it could not be applied to TestFlight. I can cancel sandbox subscriptions through Settings > App Store > Sandbox account But since TestFlight does not use sandbox account I cannot cancel a sub from there. Also, TF purchase does not appear in the list of regular subscriptions (Settings > Profile > Media & Purchases). So my question is: is there any way to manually cancel auto-renewable subscription bought in TestFlight build of the app?

We have an application that capture audio and video. App captures audio PCM on internal or external microphone and displays audio level on the screen. App was working fine for many years but after iOS 26.4 upgrade, averagePowerLevel and peakHoldLevel are stuck to -120 values. Any suggestion?

Hello, I want to echo the DeviceActivityReport "concurrency" problems flagged in https://developer.apple.com/forums/thread/720549, and ask a related question. (Thanks to Kmart and other Apple dev support folks who have been monitoring these forums and responding diligently.) I would like to display daily and weekly stats in the same view, broken down by specific apps (as in the native Screen Time). However, instantiating multiple DeviceActivityReport objects with different filters and/or different contexts leads to confusion, where the two views will incorrectly and intermittently swap data or duplicate data where it shouldn't (seemingly upon some interval when the extension provides fresh data). There isn't documentation on how to display multiple reports at once. Is the idea that logic for multiple reports should be embedded within the extension itself in the makeConfiguration() function and there should only be a single DeviceActivityReport in the main App, or is this a bug? Even with a single DeviceActivityReport, I run into inconsistencies where the View provided by the extension takes multiple seconds to load or fails to load altogether. The behavior seems random...I will build the application with the same code multiple times and see different behavior each time. Finally, a plug for better support in the Simulator for the entire set of Screen Time APIs. Thanks!

We've discovered a regression in iOS 26 where AVMutableComposition silently drops audio when the source asset is streamed over HTTP/2. The same file served over HTTP/1.1 plays audio correctly through the same composition code. Direct AVPlayer playback (without composition) works fine on HTTP/2. This did not occur on iOS 18.x. It happens on physical devices only. It does not reproduce on a simulator or on macOS. Tested conditions (same MP4 file, different CDNs): CloudFront (HTTP/2) + Composition → ❌ Audio silent Cloudflare (HTTP/2) + Composition → ❌ Audio silent Akamai (HTTP/1.1) + Composition → ✅ Audio works Apple TS (HTTP/1.1) + Composition → ✅ Audio works Downloaded locally, then composed → ✅ Audio works Direct playback, no composition (HTTP/2) → ✅ Audio works The CloudFront and Akamai URLs serve the identical file — same S3 object, different CDN edge. CDN vendor doesn't matter; any HTTP/2 source triggers it. Minimal reproduction: let asset = AVURLAsset(url: http2URL) let videoTrack = try await asset.loadTracks(withMediaType: .video).first! let audioTrack = try await asset.loadTracks(withMediaType: .audio).first! let duration = try await asset.load(.duration) let composition = AVMutableComposition() let fullRange = CMTimeRange(start: .zero, end: duration) let compVideo = composition.addMutableTrack(withMediaType: .video, preferredTrackID: kCMPersistentTrackID_Invalid)! try compVideo.insertTimeRange(fullRange, of: videoTrack, at: .zero) let compAudio = composition.addMutableTrack(withMediaType: .audio, preferredTrackID: kCMPersistentTrackID_Invalid)! try compAudio.insertTimeRange(fullRange, of: audioTrack, at: .zero) let item = AVPlayerItem(asset: composition.copy() as! AVComposition) player.replaceCurrentItem(with: item) player.play() // Video plays, audio goes silent after a while Playing the same asset directly works fine: player.replaceCurrentItem(with: AVPlayerItem(asset: asset)) player.play() // Both video and audio work Filed as FB22696516 Sample project: https://github.com/karlingen/AVCompositionBug

In the WWDC 2021 session Mitigate fraud with App Attest and DeviceCheck it is said that: App Attest is supported on devices that have a Secure Enclave, but there are cases, such as app extensions, where isSupported will still return false. The documentation shows that the following Macs have a Secure Enclave: MacBook Pro computers with Touch Bar (2016 and 2017) that contain the Apple T1 Chip Intel-based Mac computers that contain the Apple T2 Security Chip Mac computers with Apple silicon I'm using a 2018 15" MacBook Pro containing a T2 Security Chip for testing, however, DCAppAttestService.shared.isSupported always returns false in native macOS or Catalyst apps. DCDevice.current.isSupported also returns false. The documentation for DCAppAttestService shows availability on "macOS 11.0+" and "Mac Catalyst 14.0+". It appears to have been added in the macOS 11.3 SDK included in Xcode 12.5. DCDevice shows availability on "macOS 10.15+" and "Mac Catalyst 13.0+". Although both APIs are available on the listed OSes, I only ever see isSupported == false. Are App Attest or DeviceCheck functional on any Macs? If so: Are there more specific Macs that support the feature (e.g., Apple Silicon Macs only)? Are there any additional steps that need to be taken to use them (e.g., changes to entitlements, provisioning profiles or distribution through the Mac App Store)? In native macOS apps, it doesn't actually appear to be possible to add the App Attest capability in Xcode under "Signing & Capabilities". If not, I think it would be good to update the documentation with this limitation since I'd expect them to work based on the availability being "macOS 10.15+" or "macOS 11.0+" for DeviceCheck and App Attest, respectively. I imagine most others would make the same assumptions.

Hi folks, I've used a NavigationSplitView within one of the tabs of my app since iOS 16, but with the new styling in iOS 18 the toolbar region looks odd. In other tabs using e.g. simple stacks, the toolbar buttons are horizontally in line with the new tab picker, but with NavigationSplitView, the toolbar leaves a lot of empty space at the top (see below). Is there anything I can do to adjust this, or alternatively, continue to use the old style? Thanks!

Hello, I enrolled in the Apple Developer Program on March 30, 2026. The payment was successfully charged to my card and I received the receipt from Apple. However, my account is still showing "Pending" status for more than a week now. I submitted a support request but have not received any response yet. Order Number: W1557188249 Has anyone else experienced this recently? Did contacting Apple support help resolve it? Any guidance would be appreciated.

Hi all,  Apple dropping on-going development for FireWire devices that were supported with the Core Audio driver standard is a catastrophe for a lot of struggling musicians who need to both keep up to date on security updates that come with new OS releases, and continue to utilise their hard earned investments in very expensive and still pristine audio devices that have been reduced to e-waste by Apple's seemingly tone-deaf ignorance in the cries for on-going support.  I have one of said audio devices, and I'd like to keep using it while keeping my 2019 Intel Mac Book Pro up to date with the latest security updates and OS features.  Probably not the first time you gurus have had someone make the logical leap leading to a request for something like this, but I was wondering if it might be somehow possible of shoe-horning the code used in previous versions of Mac OS that allowed the Mac to speak with the audio features of such devices to run inside the Ventura version of the OS.  Would it possible? Would it involve a lot of work? I don't think I'd be the only person willing to pay for a third party application or utility that restored this functionality. There has to be 100's of thousands of people who would be happy to spare some cash to stop their multi-thousand dollar investment in gear to be so thoughtlessly resigned to the scrap heap.  Any comments or layman-friendly explanations as to why this couldn’t happen would be gratefully received!  Thanks,  em

Hello, Are there any plans to compile a python 3.13 version of tensorflow-metal? Just got my new Mac mini and the automatically installed version of python installed by brew is python 3.13 and while if I was in a hurry, I could manage to get python 3.12 installed and use the corresponding tensorflow-metal version but I'm not in a hurry. Many thanks, Alan

Hello Apple Developer Support, My app has been stuck in “Waiting for Review” since February 7, and I have submitted multiple inquiries without receiving any response. This delay has now become extremely concerning. Missing a planned launch due to an indefinite review timeline is very difficult for independent developers. If there is an issue with the submission, I would appreciate clear communication. If there are review delays, transparency would help us plan accordingly. I respect the review process, but the lack of updates after this amount of time is frustrating. I would sincerely appreciate clarification on the status. I kindly ask for a specific and personalized response regarding my case, as my previous inquiries received only general or automated replies without addressing the actual issue. Thank you.

I am using the sample app from: https://developer.apple.com/videos/play/wwdc2025/277/?time=763 I installed this on an Iphone 15 Pro with iOS 26 beta 1. I was able to get good transcription with it. The app did crash sometimes when transcribing and I was going to post here with the details. I then installed iOS beta 2 and uninstalled the sample app. Now every time I try to run the sample app on the 15 Pro I get this message: SpeechAnalyzer: Input loop ending with error: Error Domain=SFSpeechErrorDomain Code=10 "Cannot use modules with unallocated locales [en_US (fixed en_US)]" UserInfo={NSLocalizedDescription=Cannot use modules with unallocated locales [en_US (fixed en_US)]} I can't continue our our work towards using SpeechAnalyzer now with this error. I have set breakpoints on all the catch handlers and it doesn't catch this error. My phone region is "United States"

Beta testers outside the US, for our MacOS App, are being told their ID is not valid in the US Store and that they must switch to a store in their country. Yet the store switch fails Essentially beta testers outside the US cannot do testflight sandbox eCommerce for the Mac version of our app. Note that eCommerce on the Mac works for US based testers and eCommerce for the iOS/iPadOS works for testers in all territories. Many of these testers are in India, the UK and Canada. We believe that this is incorrect, that storeKit is not correctly detecting the AppStore Region for mac based testflight eCommerce. At this point we have 382 testers, most outside the US and we can only Beta Test our app with US users. Attached are images of the messages that are coming from storeKit: Here is a link to a video from a user in Canada who is demonstrating the problem (cut and paste into browser) https://youtu.be/kB818wfVld4 Here is another link to a video from a user in Canada who is demonstrating the problem (cut and paste into browser). https://youtu.be/7uAZKo8wpfU We see that there is another post with a similar problem. Similar eCommerce Problem Because eCommerce works in all territories on iOS/iPadOS but ONLY in the US for Mac we suspect that this is an error that either a DBA or a coder will need to fix. Any insights from anyone would be appreciated.

In the latest 26.5, when creating a VM we can no longer disable SIP. We have confirmed we're using the proper admin user (anka) and its proper password (same one we log into the GUI with). It just keeps asking for the password as if it's wrong. It's critical we can disable SIP for VMs like we have been in previous versions.

FB: https://feedbackassistant.apple.com/feedback/22556883 We're seeing a small number of production users where both Transaction.currentEntitlements and Transaction.all return zero transactions for a valid, active, non-refunded non-consumable IAP.

Could someone please explain how to use a custom sound when setting up an alarm using AlarmKit? It keeps playing a default sound. Also, I keep having an issue where the alarm sound plays but doesn’t show the alarm interface buttons unless the screen is locked.

Hello, my Apple Developer Program had expired 20 days ago, but i cant renew in any way (auto-renew dont work, i dont have "renew button" on web, dont have it in iOS and macOS developer apps, so i cant renew it. Has anyone encountered this problem? How can i solve it and renew my membership?

Greetings! I'm preparing to publish an app in Apple Store. It's a 2D Audio app made in Godot, already published in Google Store.. As we know, OpenGL is considered deprecated since iOS 12 / 2018 .. However given the current state of Metal, or Vulkan integration in Godot, and with the idea of bringing the Best possible experience on iOS.. I'm not completely sure what will be the best API to use as primary option.. -As good as Metal, or even Vulkan work in Godot; the fact of the matter is, each API has its strong and weak points.. -Metal: Native on iOS, fully compliant and supported. However it has two weak points: Initial Compilation Freeze - +5 sec. Performance Hit, (although negligible for final user) app uses 25% more CPU (on my iPhone 12). Battery drain? -Vulkan: In godot, Vulkan > MoltenVk > Metal More complex translation layer, but interestingly gives slightly better Performance than Metal.. Initial Compilation doesn't cause Freeze, because is lazy/delayed and performed while the app is starting. Uses 25% less CPU than Metal and gives slightly more stable Framerate. (iPhone 12) However, given the extra complexity it could be more prone to error, or Compatibility Problems, which are known and have been reported with older iOS devices (iPads come to mind..) Right? -OpenGL: No Initial Compilation Needed Max Performance, No CPU munch Universally supported, (in theory?) works Perfectly on my iPhone 12 with iOS 26.3 and 26.4.2 And all in all, gives the best Performance and user experience. -And that's pretty much the situation! Since the graphics API of choice, will have an effect and directly translate to User experience... what's then the best one? -This will be the first app I Publish on Apple Store, so as you can imagine I want to Comply with Apple as much as possible; and bring iOS users the best possible experience. However each one of the APIs seem to have a negative aspect.. Metal: 5sec Compilation Freeze Vulkan: Compatibility Problems? OpenGL: "Deprecated" In practical terms, right now, OpenGL gives the best Performance, and the best User Experience.. So what to do? -The Android version is published in Google Store in OpenGL Compat mode. Works perfectly. Even tho OpenGL has been Deprecated on iOS for 7+ years, it has survived all along, with no announced removal date from Apple. And it seems to work perfectly and be fully operational up to the latest iOS 26 version.. right? Maybe Apple is maintaining it for stability and compatibility reasons, even if they're no longer actively developing it? Butthee "deprecated" label sounds alarming, as if support could drop any day.. So what will be the best choice in this situation? -Will an app built primarily for OpenGL, (with Metal fallback) be Rejected right away in Apple Store? -Otoh Vulkan (via MoltenVK) could be a middle term solution, second best Performance, no Compilation Freeze.. But yeah, the Compatibility aspect is important; and while considerable improvements have been made in Godot's implementation, the current status or possible outcome is harder to assess.. Both Metal and OpenGL seem safer options in that sense..

I just signed up in the developer program and I want to change my primary language of App store connect: https://appstoreconnect.apple.com/both App dev program and apple id interface are set to English but Appstore connect is set to French by default. Thanks.

HI there, ive registered Apple ID for distrobution Apps, enrollment was not completed properly and ive interested in cashback for enrollment to start enrollment again, but in second time there was written "complete your enrollment" and it requested from me second payment. QUestion is: can I cashback my first enrollment and why devpayment@apple.com dont awnsered me for a week?P.S. I was mailed from Apple ID, marked with "Your order has been canceled."
