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 have been getting the following error intermittently (once it happens, then its consistent) when I try to build my app
Showing Recent Errors Only
Unable to resolve build file: BuildFile<b11862f281fd8c8287d499b4f0922a9c61c95323d2196ba877ed344a02baffbb> (The workspace has a reference to a missing target with GUID '0c7e19da3805e0a412c717704d4549fc25560b498add930cbef9623bd9afb53a')
There have been no changes to my project (git status is clean). I have tried cleaning DerivedData as well, but it did not help.
How am I supposed to figure out from the GUID what is it that xcode is trying to find?

Hello, I've been searching online for ways to remedy this issue for the past 3 days and this is my last resort.
The Issue
Build on device fails to connect to the device.
The prompt will permanently be stuck loading in that screen. Finder is able to connect to the device, just that Xcode is unable to.
Xcode does prompt for passcode on the device, and I have entered it accordingly.
I note that i AM on VPN, but even disabling VPN and turning off Wifi does not fix the issue.
This was working until several days ago. Not sure what the issue is.
Fixes Attempted
Tried with a different cable, and USB ports
Tried with different devices (multiple devices both iPad and iPhone has the same issue)
Turn Off and On developer mode on devices.
Clear Trusted Computers on devices.
Updating both devices to the latest iOS version.
Quitting Xcode
Clearing derived cache
Restarting Macbook
Updating to the latest iOS version on Macbook
Reinstalling Xcode
toggling signing certificates
I was trying other fixes like "pkill usbmuxd", but since I am on corporate hardware, i will be required to escalate it if i require sudo permissions.
Is anyone able to provide a concrete solution or explanation why this happens?
Development environment:
MacBook pro
Apple M1
macOS Tahoe 26.2 (25C56)
Xcode 26.x
iPhone 6 Plus / iOS 12.4.4
Exception description:
After I upgraded to Xcode 26, my iPhone 6 Plus had a system version of 12.4.4. I was unable to perform real-device debugging, whether for existing projects or new ones. The error message from Xcode was as follows:
Could not launch “xxx”
Domain: IDEDebugSessionErrorDomain
Code: 3
Failure Reason: Cannot launch '/private/var/containers/Bundle/Application/A44062C1-32F5-4346-B13C-FC3F39EAF7A1/xxx.app': Unspecified
Even though I have already added device support for the iOS 12.4
Has Xcode 26 stopped supporting the debugging of any devices running iOS 12 system?
Hi there, I am trying to use the agentic coding with the new Xcode update, however the "Intelligence" tab is not coming up on the left hand side of my Xcode settings. I've ensured I have macOS greater than 26, I've got Apple Intelligence and Siri enabled. I've shut down and restarted Xcode and my computer. Still, the option is not available.
Can anyone help?

I tried cleaning every cache, and logging in and out of my account.
I saw some reddit posts where they suggested to check out VPNs, host files and other stuff but everything was okay, also I can reach apple cdns etc.
I also tried using Xcode beta 26.4 and going back to 26.2 but still the same problem.
Anyone has a solution?
I was having an issue with the new xcode and was forced to to go back to to Xcode 26.0.1. ( I need iOS simulators for mobile testing and as Developer I know is using this version with no problems). I've always install xcode from the app store with no issue so installing from Apple Dev was something new for me so So I did the following
downloaded Xcode 26.0.1
Extracted it from Xzip
added the extracted Xcode version to the applications folder
click the Xcode icon
Expected result
I was expecting to see text i could install Xcode version
Actual Result
Xcode opened
Asked me to create a project
When project was created I saw
Question.
What did I do wrong?
How do I fix it?
Have a peculiar problem I'm not able to solve. Working on an app with a mapview in the max zoomed out globe level. For some reason this morning Xcode froze/crashed when I was working and I had to force quit to get it back up. Then a new issue of graphical artifacts on the space section of the Mapview showed up.
This Tuesday has now been spent in full on trying to solve this to no avail.
I created a new project for iOS/iPadOS and added a similar map implementation. It works fine.
I used Claude to help me after a few reinstalls of Xcode with this. I asked claude to summarize - this is what has been done:
Claude generative AI summary starts here----------
Here's a complete summary of everything attempted:
The Problem
SwiftUI tvOS app with MapKit globe view showing severe rendering artifacts — corrupted pixels surrounding the globe. Started after Xcode crashed while the tvOS simulator was actively running. iOS simulator, macOS Maps app, and all native apps work perfectly. Only tvOS simulator MapKit is affected.
Hardware Confirmed Fine
Geekbench 6 Metal GPU score: 124,666 (normal for M1 Max)
Apple Diagnostics (Apple Silicon method): No issues found
macOS Maps globe renders perfectly
Everything That Was Attempted
Simulator resets:
Erased all simulator content and settings
Created brand new simulator devices
Deleted derived data
Killed CoreSimulator service
Runtime reinstalls:
Removed and reinstalled tvOS platform runtime multiple times
Tested on Xcode 26.3 and 26.4 beta — same issue on both
Installed fresh tvOS runtime after full Xcode reinstall
Cache clearing:
~/Library/Caches/com.apple.CoreSimulator
~/Library/Saved Application State/com.apple.iphonesimulator.savedState
All Metal shader caches in /private/var/folders/ including:
com.apple.CoreSimulator.SimRenderingServices.SimMetalHost
com.apple.CoreSimulator.SimRenderingServices.SimRenderServer
com.apple.CoreSimulator.CoreSimulatorService
com.apple.iphonesimulator
com.apple.dt.Xcode
com.apple.dt.xcodebuild
com.apple.CoreSimulator.simctl
~/Library/Developer/Xcode/XcodeToMetalToolchainIndexMapping.plist
~/Library/Developer/Xcode/SDKToSimulatorIndexMapping.plist
~/Library/Developer/Xcode/DerivedData
Full Xcode reinstall:
Deleted Xcode completely
Removed ~/Library/Developer
Removed all Xcode-related caches and preferences
Fresh install from Mac App Store
APFS simulator volume cleanup (required disabling SIP):
Discovered 138GB of orphaned APFS simulator volumes in /Library/Developer/CoreSimulator/Volumes/ that were protected by SIP and couldn't be deleted normally
These volumes were left in a corrupted/limbo state from the original Xcode crash
Temporarily disabled SIP via Recovery Mode
Successfully deleted all orphaned volumes
Re-enabled SIP
Reinstalled fresh tvOS runtime
Metal Toolchain:
Found three leftover Metal Toolchains (17A324, 17A5241c, 17A5295f) in Xcode settings
Cleared toolchain index mapping file
Reinstalled fresh Metal Toolchain with new tvOS runtime
Current State
Fresh Xcode installation
Fresh tvOS runtime
All simulator volumes cleared
SIP re-enabled
Issue still persists
What Has NOT Been Checked
/Library/Developer/CoreSimulator/Cryptex
/Library/Developer/CoreSimulator/Images
/Library/Developer/CoreSimulator/Profiles
Conclusion
This is almost certainly a bug triggered by the hard Xcode crash corrupting something at a level that has survived complete reinstallation of Xcode and all simulator components. The corruption is somewhere in a system-level component that normal developer tools cannot reach. Requires Apple Developer Technical Support or escalation via Feedback Assistant with the full timeline and screenshots.
For Apple's reference:
Machine: MacBook Pro M1 Max
Xcode: 26.3 / 26.4 beta (both affected)
Started: After hard Xcode crash while tvOS simulator was actively rendering MapKit globe
Affected: tvOS simulator MapKit globe only
Not affected: iOS simulator, macOS Maps, all native apps
----------(Claude generative AI summary ends here) -----------
Anyone seen this before? Absolutely wild. Can't think of more things to try.
Been eyeing a new Macbook for a while. Strange coincidence that the new M5 Macbook Pros dropped today :D But in sum it does not seem like a GPU issue since the same rendering works on the iOS sim.
Thanks!

Hi, I submitted my Swift Student Challenge 2026 app and I'm worried about a build error I got when testing.
I have both PlateClassifier_2.mlmodel and PlateClassifier_2.mlmodelc in my Sources folder. Only the .mlmodelc is listed in my Package.swift resources. When building I got:
PlateClassifier_2.mlmodel: No predominant language detected. Set COREML_CODEGEN_LANGUAGE to preferred language.
Build failed — 1 error
Will judges hit this same error? Does having an unlisted .mlmodel alongside the .mlmodelc cause a hard build failure on other machines too, or is this specific to my setup (Xcode 26.2 beta, building to physical device)?
Will this get me instantly disqualified? Any help appreciated.
For me it looks like Xcode 26 has problems reading SPM packages from a locally hosted BitBucket git solution.
While Xcode 16 work perfectly fine, Xcode 26 fails to load and gives "Server SSH Fingerprint Failed to Verify" as error description. Cleaning build data and DerivedData sometimes makes loading work. Any change in Package dependencies will break it again.
Anyone having same problems? How do you handle it?

Hello,
I'm currently investigating an issue related to iOS credit card autofill (Payments & Card Details) in our mobile application.
Our app is built using React Native, and we are implementing card input fields using TextInput with the required autofill configuration:
autoComplete="cc-number"
textContentType="creditCardNumber"
Despite correctly configuring these properties, credit card autofill is not being triggered on iOS devices.
I would appreciate clarification on:
Is credit card autofill officially supported for React Native TextInput fields using autoComplete="cc-number" and textContentType="creditCardNumber"?
Are there any additional requirements (entitlements, associated domains, specific configurations, etc.) needed for payment autofill to work?
Is autofill expected to work inside WKWebView contexts?
Are there any known limitations or restrictions for third-party frameworks such as React Native?
I would appreciate any guidance or documentation you can share regarding the expected behavior and official support for this scenario

Hello,
We have been trying to contact the Apple Developer Support for some time now regarding a couple of issues. For a couple of months now we are seeing that we are getting an error when we visit https://developer.apple.com/contact and the topics aren't loaded at all. After seeing the network traffic in the developer tools I see that we get a "Failed to load resource: the server responded with a status of 500 (Internal Server Error)" when making a request to the services/userProfile/ endpoint. The weird part is that the response contains our userProfile just fine. The only thing that I see in the payload that could be an issue is the resultCode that is 0. Has anyone encountered this before or has any idea on what we can do? I don't see an alternative way to contact Apple in order to resolve this issue.
