Overview

Hello everyone. I use Translation Framework in my application. During development everything was fine, Translation framework worked well, but after two or three days of using the production version (that was published in AppStore and available for others also!) - my application stopped working. Translation framework gives errors: Error sending 1 paragraphs Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} Failed to translate input 0; returning error: Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} Received unbridged NSError to API, converting to .internalError: Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} Once again - it worked when I developed it, it was released on the AppStore, and suddenly it stopped working!

I have an iOS and macOS app that includes a file provider extension. on macOS is is perfect no issues anywhere. on iOS it works for small datasets or if I do read only operations. as soon as I try to do anything with larger files I quickly hit the 20MB limit. I have solved file transfers by using chunking but when it comes to listing a folder with a couple thousand files it instantly crashes the FPE with an OOM error. works ok up to 100 files but anything beyond that crashes. I know enumerate items supports batches however the initial load form say a webdav server that has no concept of pagination will always fail to load in pieces no matter what I do. This likely explains why WebDAV was never implemented on iOS. in any case can you possibly consider upgrading the memory limit for FPE's or provide some mechanism to call our full iOS app for more processing power in the background to handle requests on demand? I do not understand where 20MB is a reasonable number. even 100MB seems more reasonable with everything have much more memory these days this seems incredibly limiting. even an option to request increased memory with a capability would be fine but that only works for the app itself not the FPE target. please advise if there is anything that can be done.

We’ve encountered what appears to be a CoreML regression between macOS 26.0.1 and macOS 26.1 Beta. In macOS 26.0.1, CoreML models run and produce correct results. However, in macOS 26.1 Beta, the same models produce scrambled or corrupted outputs, suggesting that tensor memory is being read or written incorrectly. The behavior is consistent with a low-level stride or pointer arithmetic issue — for example, using 16-bit strides on 32-bit data or other mismatches in tensor layout handling. Reproduction Install ON1 Photo RAW 2026 or ON1 Resize 2026 on macOS 26.0.1. Use the newest Highest Quality resize model, which is Stable Diffusion–based and runs through CoreML. Observe correct, high-quality results. Upgrade to macOS 26.1 Beta and run the same operation again. The output becomes visually scrambled or corrupted. We are also seeing similar issues with another Stable Diffusion UNet model that previously worked correctly on macOS 26.0.1. This suggests the regression may affect multiple diffusion-style architectures, likely due to a change in CoreML’s tensor stride, layout computation, or memory alignment between these versions. Notes The affected models are exported using standard CoreML conversion pipelines. No custom operators or third-party CoreML runtime layers are used. The issue reproduces consistently across multiple machines. It would be helpful to know if there were changes to CoreML’s tensor layout, precision handling, or MLCompute backend between macOS 26.0.1 and 26.1 Beta, or if this is a known regression in the current beta.

Hi, In our app we are using DeviceCheck (App Attest) in a production environment iOS. The service works correctly for most users, but a user reported failure in a flow that use device check service. This failure is not intermittently, it is constant. We are unable to reproduce this failure and we are believing that this failure occurred by new version ios 26.3 because for others users using early versions the service is normally. Environment iOS 26.3 Real device App Attest capability enabled Correct App ID, Team ID and App Attest entitlement Production environment Characteristics: appears constantly affects only unique user -Don't resolves after time or reinstall not reproducible on our test devices NSError contains no additional diagnostic info (Error Domain=com.apple.devicecheck.error Code=3 "(null)") We saw about this error code 3 in this post 812308, but it's not our case because the ios version in this case is not iOS 17.0 or earlier. Please, help us any guidance for solution. Thank you

SMBClient-593 introduces a crtitical bug. When reading and writing data at high volume, the SMBClient no longer properly receives and handle responses from the server. In some cases, the client mishandles the response packet and the following errors are seen in the logs: 2025-12-02 21:36:04.774772-0700 localhost kernel[0]: (smbfs) smb2_smb_parse_write_one: Bad struct size: 0 2025-12-02 21:36:04.774776-0700 localhost kernel[0]: (smbfs) smb2_smb_write: smb2_smb_read_write_async failed with an error 72 2025-12-02 21:36:04.774777-0700 localhost kernel[0]: (smbfs) smbfs_do_strategy: file.txt: WRITE failed with an error of 72 In other cases, the client mishandles the response packet and becomes completely unresponsive, unable to send or receive additional messages, and a forced shutdown of the computer is required to recover. This bug is only present on macos 26. We believe the operative change is in the latest commit, SMBClient-593 beginning at line now 3011 in smb_iod.c. The issue seems to be a race, and occurs much more frequently once throughput exceeds around 10Gbps, and again more frequently above 20Gbps.

Description Enterprise users are experiencing VPN resource access failures after upgrading to macOS Tahoe. Investigation indicates that configd (specifically IPMonitor) is incorrectly re-ranking network interfaces after a connectivity failure with probe server. This results in DNS queries routing through the physical network adapter (en0) instead of the VPN virtual adapter, even while the tunnel is active. This behaviour is not seen in previous macOS versions. Steps to Reproduce: Connect to an enterprise VPN (e.g., Ivanti Secure Access). Trigger a transient network condition where the Apple probe server is unreachable. For example make the DNS server down for 30 sec. Observe the system routing DNS queries for internal resources to the physical adapter. Expected Results The: VPN virtual interface should maintain its primary rank for enterprise DNS queries regardless of the physical adapter's probe status. Actual Results: IPMonitor detects an UplinkIssue, deprioritizes the VPN interface, and elevates the physical adapter to a higher priority rank. Technical Root Cause & Logs: The system logs show IPMonitor identifying an issue and modifying the interface priority at 16:03:54: IPMonitor Detection: The process identifies an inability to reach the Apple probe server and marks en0 with an advisory: Log snippet 2026-01-06 16:03:53.956399+0100 localhost configd[594]: [com.apple.SystemConfiguration:IPMonitor] configd[594] SetInterfaceAdvisory(en0) = UplinkIssue (2) reason='unable to reach probe server' Interface Re-ranking: Immediately following, IPMonitor recalculates the rank, placing the physical service ID at a higher priority (lower numerical rank) than the VPN service ID (net.pulsesecure...): Log snippet 2026-01-06 16:03:53.967935+0100 localhost configd[594]: [com.apple.SystemConfiguration:IPMonitor] 0. en0 serviceID=50CD9266-B097-4664-BFE6-7BAFCC5E9DC0 addr=192.168.0.128 rank=0x200000d 2026-01-06 16:03:53.967947+0100 localhost configd[594]: [com.apple.SystemConfiguration:IPMonitor] 1. en0 serviceID=net.pulsesecure.pulse.nc.main addr=192.168.0.128 rank=0x2ffffff 3.Physical adapter Is selected as Primary Interface: 2026-01-06 16:03:53.968145+0100 localhost configd[594]: [com.apple.SystemConfiguration:IPMonitor] 50CD9266-B097-4664-BFE6-7BAFCC5E9DC0 is the new primary IPv4 configd[594]: 50CD9266-B097-4664-BFE6-7BAFCC5E9DC0 is the new primary DNS Packet Trace Evidence Wireshark confirms that DNS queries for enterprise-specific DNS servers are being originated from the physical IP (192.168.0.128) instead of the virtual adapter: Time: 16:03:54.084 Source: 192.168.0.128 (Physical Adapter) Destination: 172.29.155.115 (Internal VPN DNS Server) Result: Connectivity Failure (Queries sent outside the tunnel)

Apple's new Spatial Personas use Gaussian Splatting, but I have not found any APIs for visionOS to display a Gaussian Splat like a PLY file. Am I just missing the Apple documentation? If not, are there common practices developers are using for displaying Gaussian Splats in visionOS?

Hi everyone, I'm experiencing an inconsistent behavior with the Translation framework on iOS 18. The LanguageAvailability.status() API reports language models as .installed, but translation fails with Code 16. Setup: Using translationTask modifier with TranslationSession Batch translation with explicit source/target languages Languages: Portuguese→English, German→English Issue: let status = await LanguageAvailability().status(from: sourceLang, to: targetLang) // Returns: .installed // But translation fails: let responses = try await session.translations(from: requests) // Error: TranslationErrorDomain Code=16 "Offline models not available" Logs: Language model installed: pt -> en Language model installed: de -> en Starting translation: de -> en Error Domain=TranslationErrorDomain Code=16 "Translation failed"NSLocalizedFailureReason=Offline models not available for language pair What I've tried: Re-downloading languages in Settings Using source: nil for auto-detection Fresh TranslationSession.Configuration each time Questions: Is there a way to force model re-validation/re-download programmatically? Should translationTask show download popup when Code 16 occurs? Has anyone found a reliable workaround? I've seen similar reports in threads 791357 and 777113. Any guidance appreciated! Thanks!

I’m currently facing a disk space limitation on my Mac. I’ve already freed up some storage by following the suggestions shared in a previous post, which helped partially, but the issue is not fully resolved and space is still a bottleneck for my workflow. To move forward, I’d like to ask a very concrete question: Is it safe and supported to move Xcode to an external hard drive (SSD), use it from there, and simply connect the drive whenever I need to work with Xcode? Specifically: Are there known issues with performance, stability, or updates? Are there components that must remain on the internal disk to avoid unexpected behavior? Is this a reasonable long-term setup, or just a temporary workaround? I want to make sure I’m not setting myself up for hidden problems down the road. Thanks in advance for any clarification or best practices you can share.

I’m hoping to get some insight from Apple engineers or developers who have seen similar behavior. Background We previously had a React Native / Expo iOS app in production for several years. Recently, we rebuilt the app completely from scratch as a native SwiftUI app using WKWebView (no shared code, no RN runtime). The new app architecture is: Native SwiftUI container WKWebView loading a remote web app Firebase Analytics & Crashlytics Push notifications (APNs + FCM) No local database, no persistent native state Migration scenario Users update the app via the App Store: Old app: React Native / Expo New app: native SwiftUI + WKWebView For most users, the migration works fine. However, for a about 10% of users, the following happens: The issue After updating from the old React Native app to the new SwiftUI app: The app opens The native landing screen appears (solid black OR blue background, depending on which most recent version if being installed) The app never transitions to the WKWebView No crash Force-quitting does not help Deleting the app completely and reinstalling does fix it 9/10 times, but NOT ALWAYS. From the user’s perspective: “The app is stuck on a black OR blue screen forever.” Important detail Most of the times, a full uninstall + reinstall FIXES the issue, but funny enough, NOT always.. In some cases, the issue persists: What we’ve already tried Over the last weeks, multiple iOS developers have investigated this. We have implemented and/or tested: Full rebuild in SwiftUI (no RN remnants) Aggressive cleanup on first launch after update: -- UserDefaults cleanup -- WKWebsiteDataStore cleanup -- URLCache / cookies cleanup Timeouts and fallbacks so the UI never blocks indefinitely Explicit logging of: -- app_open -- session_start -- webview_init -- webview_load_start / finish -- blank screen detection Handling: -- WKWebView content process terminated -- network / TLS / DNS errors Added a native SwiftUI landing screen (in the latest version) so users no longer see a black screen, but now they see a BLUE screen when the transition fails Observations from Analytics & Crashlytics No native crashes Very high user engagement (~99%) Very low blank-screen detection (~1–2%) The issue does not appear to be mass-scale But support still receives complaints daily from affected users This suggests a device / iOS / network-specific edge case, not a general migration failure. Hypotheses (not confirmed) We suspect one of the following, but haven’t been able to prove it: WKWebView failing to initialize under specific conditions after App Store updates TLS / ATS / CDN edge behavior affecting first WKWebView load iOS lifecycle timing issue when transitioning from SwiftUI landing view to WKWebView OS-specific WebKit state that survives reinstall (keychain? system WebKit state?) ISP / DNS / IPv6-related issues on first launch What we’re looking for We would really appreciate insight on: Are there known cases where WKWebView fails silently after an App Store update, even after reinstall? Is there any system-level WebKit state that survives app deletion? Are there best practices for transitioning from a SwiftUI landing view to WKWebView to avoid dead-ends? Any known iOS versions / device classes where this behavior is more common? Any debugging techniques beyond Crashlytics / Analytics that could surface what WebKit is failing on? We’re not looking for generic “clear cache” advice — we’ve already gone far down that path. We’re trying to understand whether this is a known WebKit edge case or something we are fundamentally missing. Thanks in advance for any pointers or shared experiences.

Hi, we have developed an application that streams data from two BLE peripherals at a rate of 14.5kbps per peripheral. Until now, our devices streamed in near real time with no lag on all Apple devices with Bluetooth 5.0 or greater. Since the release of the iPhone 17 series and the iPad A16, we have reports from users of the data being streamed at significantly lower rates than expected. Any help here would be greatly appreciated as our customers are being affected by this change.

I am having what feels like an endless nightmare trying to convert from an individual to an organisation. I had set up a bank account with my individual, done a WEN-BEN-8 or whatever it is called, then found out that I would need to do an organisation so that my name was not splashed around with my app. I created a company, got an ABN, an ACN, a DUNS, a bank account, a GST (even though I'm technically exempt in Australia - I doubt I will earn more than $300), and now I can't seem to change my bank account to a business account or do the WEN-BEN-8 rubbish for my organisation. This is literally harder than writing a game. I was asked for a letter of employment, but when I said, 'Do you want me to write a letter to myself, from myself, employing myself' - they did a half migration.... I am sitting stuck in limbo with an approved app, and a half-transferred organisation account... any tips on how I can resign the paid app agreement on the 'business account' when that is not being offered? Sorry for the rant, but over two weeks with this back and forth and I've developed an eye twitch...

Hello, after updating macOS to 26.2 and Xcode to 26.2 (Build 17C52), I am unable to build a Flutter iOS application for the simulator. Environment: macOS 26.2 (darwin-arm64) Xcode 26.2 (17C52) Flutter 3.38.7 (stable) Dart 3.10.7 CocoaPods 1.16.2 Target device: iPhone 16e Simulator (iOS 26.x) Issue: The build fails during the Flutter Xcode build phase with this error: Unhandled exception: Null check operator used on a null value #0 Context._embedNativeAssets (file:///opt/homebrew/share/flutter/packages/flutter_tools/bin/xcode_backend.dart:341) Command PhaseScriptExecution failed with a nonzero exit code. Additional info: Runner target uses Pods-Runner.debug/profile/release.xcconfig correctly SUPPORTED_PLATFORMS = iphoneos iphonesimulator SDKROOT resolves to iPhoneOS26.2.sdk even when building for simulator Build Settings and Run Script phases are default Flutter-generated Issue occurs both via flutter run and directly from Xcode Project worked before macOS/Xcode update It appears Xcode 26.2 may be resolving SDKROOT or build environment incorrectly for Flutter projects, causing Flutter’s xcode_backend.dart to crash. Could you please advise whether this is a known issue or requires a workaround? Thank you. Best regards David

My application needs local network access. When it is started for the first time, the user gets a prompt to enable local network access (as expected). The application is then shown as enabled in Privacy & Security / Local Network and local network access is working. If macOS is then shutdown and restarted, local network access is blocked for the application even though it is still shown as enabled in Privacy & Security / Local Network. Local network access can be restored either by toggling permission off and on in Privacy & Security / Local Network or by disabling and enabling Wi-Fi. This behaviour is consistent on Sequoia 15.1. It happens sometimes on 15.0 and 15.0.1 but not every time. Is my application doing something wrong or is this a Sequoia issue? If it is a Sequoia issue, is there some change I can make to my application to work around it?

I have an iOS app (1Address) which allows users to share their address with family and friends using CloudKit Sharing. Users share their address record (CKRecord) via a share link/url which when tapped allows the receiving user to accept the share and have a persistent view into the sharing user's address record (CKShare). However, most users when they recieve a sharing link do not have the app installed yet, and so when a new receiving user taps the share link, it prompts them to download the app from the app store. After the new user downloads the app from the app store and opens the app, my understanding is that the system (iOS) will/should then vend to my app the previously tapped cloudKitShareMetadata (or share url), however, this metadata is not being vended by the system. This forces the user to re-tap the share link and leads to some users thinking the app doesn't work or not completing the sharing / onboarding flow. Is there a workaround or solve for this that doesn't require the user to tap the share link a second time? In my scene delegate I am implementing: func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {...} And also func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {...} And also: func windowScene(_ windowScene: UIWindowScene, userDidAcceptCloudKitShareWith cloudKitShareMetadata: CKShare.Metadata) {...} And: func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {...} Unfortunately, none of these are called or passed metadata on the initial app run after install. Only after the user goes back and taps a link again can they accept the share. This documentation: https://developer.apple.com/documentation/cloudkit/ckshare says that adding the CKSharingSupported key to your app's Info.plist file allows the system to launch your app when a user taps or clicks a share URL, but it does not clarify what should happen if your app is being installed for the first time. This seems to imply that the system is holding onto the share metadata and/or url, but for some reason it is not being vended to the app on first run. Open to any ideas here for how to fix and I also filed feedback: FB20934189.

Hi, happy new year, I'm a Product Manager for a communications app that's currently in testflight. We requested the com.apple.developer.usernotifications.filtering entitlement on December 3rd, and have yet to receive a response from Apple. I understand that the holiday break may have gotten in the way, however it feels like we were lost in the queue as it's been 6 weeks with no response. Our app owner has checked-in inside appstoreconnect but has not received anything back. Is this common? Is there any process for getting a status update? Are we doing something wrong? Without this entitlement we cannot make the device ring in the background. The app is a voice and video messaging platform.
