DEXT (IOUserSCSIParallelInterfaceController): Direct I/O Succeeds, but Buffered I/O Fails with Data Corruption on Large File Copies
Hi all, We are migrating a SCSI HBA driver from KEXT to DriverKit (DEXT), with our DEXT inheriting from IOUserSCSIParallelInterfaceController. We've encountered a data corruption issue that is reliably reproducible under specific conditions and are hoping for some assistance from the community. Hardware and Driver Configuration: Controller: LSI 3108 DEXT Configuration: We are reporting our hardware limitations to the framework via the UserReportHBAConstraints function, with the following key settings: // UserReportHBAConstraints... addConstraint(kIOMaximumSegmentAddressableBitCountKey, 0x20); // 32-bit addConstraint(kIOMaximumSegmentCountWriteKey, 129); addConstraint(kIOMaximumByteCountWriteKey, 0x80000); // 512KB Observed Behavior: Direct I/O vs. Buffered I/O We've observed that the I/O behavior differs drastically depending on whether it goes through the system file cache: 1. Direct I/O (Bypassing System Cache) -> 100% Successful When we use fio with the direct=1 flag, our read/write and data verificatio

Reply to Concurrency warning in Translation API
This is tricky. My best guess is that translationTask(_:action:) is missing all the magic concurrency decorations required to make this work nicely. To get this to build right now you can mark the closure as sendable, like so: .translationTask(configuration) { @Sendable session in do { try await session.prepareTranslation() } catch { // Handle any errors. } } This compiles in Xcode 26.1 using the Swift 6 language mode and: Approachable Concurrency enabled Default Actor Isolation set to MainActor Note I’m using prepareTranslation() in my examples because it’s simpler, and that makes it easier to focus on the core issue. The drawback to this is that you can no longer access main-actor-isolated state from the closure. You can work around that using MainActor.run(…): try await session.prepareTranslation() … no isolation … await MainActor.run { … main-actor isolated … } Clearly this is less than ideal and I encourage you to file a bug against… actually, I think it’d be best to file a bug against the Translating

Reply to OSLog is not working when launching the app with Siri.
One thing that may be happening here is that your app is launching without the debugger attached, which is where Quinn's points about the system log come in. You can use the macOS Console app to look for your logs once you're using OSLog. Something I like to do in addition to that is configure LLDB to wait to attach until your process is launched. That way, when you use Siri to launch the app, the logs you're expecting will be picked up in the LLDB console. You can configure this in your Xcode scheme, under the Run options. With that configuration set, if you press the Run button in Xcode, the system starts LLDB, but not your app like usual when you press the Run button. You can then launch your app through Shortcuts or Siri, LLDB will now attach automatically, and record all of your OSLog statements inside of Xcode for that launch sequence. — Ed Ford,  DTS Engineer

ASWebAuthenticationSession.start() does not display authentication UI on macOS (no error, no callback)
Hello Apple Developer Community, I'm experiencing an issue on macOS where ASWebAuthenticationSession fails to display its authentication window.

LLDB and environment variables in Xcode
Hey! I am writing type formatting scripts in Python for lldb, as described in https://lldb.llvm.org/use/variable.html#python-scripting. I'm trying to pass an environment variable to lldb from Xcode to determine the path to the scripts in the project root, so the project is not bound to some predetermined path. I am having trouble doing this in Xcode. What I have tried: lldbinit file Create a .lldbinit file in $(SRCROOT) with the following content: platform shell echo $SRCROOT.

Question About iOS Link Association Behavior and How to Reset App-Link Preferences
Hello, I would like to clarify how link association and app-opening preferences work in iOS, specifically when a user opens a URL in a browser that can be handled by an installed application. I have noticed the following behavior: When a user taps a URL that can be opened by an app, iOS sometimes asks whether to open the link in the app or continue in the browser. After choosing an option once (for example, Open in App or Stay in Browser), it seems that this preference becomes persistent. Even after deleting the application and reinstalling it, the browser (Safari or third-party browsers) sometimes continues to open the link directly in the browser without asking the user again. In some cases, it appears impossible to reset or clear this association, and the user is not prompted again to choose how the link should be opened. My questions are: How exactly does iOS store link-handling preferences between apps and browsers? Are these preferences saved on the system level, inside Safari, or associated with the ap

Mail relay not allowed
Dear Sir or Madam, Thank you for your continued support. My name is Sato from atmos. We are currently working with a vendor to implement Apple Sign In as a login method for our app, but we are encountering some issues and would like to contact you about them. The Apple Sign In functionality itself is almost complete, but during verification, email relay is not permitted by Apple when Apple Sign In is used with a non-public email address, making it impossible to complete email relay verification for users. We have reviewed the settings in “/account/resources/services/configure,” checked your FAQ, and explored all other possible solutions within our scope, but the situation remains unchanged. Would it be possible for your team to confirm the cause of the email relay not being permitted? Thank you for your assistance. atmos Sato Translated with DeepL.com (free version)

Reply to DEXT (IOUserSCSIParallelInterfaceController): Direct I/O Succeeds, but Buffered I/O Fails with Data Corruption on Large File Copies
We've observed that the I/O behavior differs drastically depending on whether it goes through the system file cache: Quick question— how are you validating what the actual issue is? More specifically, are you pulling, unmounting the device, and testing with a known good driver? Or are you testing with your development DEXT? That's crucial because testing through your DEXT means you don't know whether this is a write or a read issue. That leads to here: At the end of the operation, to ensure data is flushed to disk, the macOS file system issues an fsync, which is ultimately translated into a SYNCHRONIZE CACHE SCSI command (Opcode 0x35 or 0x91) and sent to our UserProcessParallelTask_Impl. Are you sure about that? How have you validated that? I haven't tried to validate the entire I/O path, but I’m fairly sure that copyfile() (what cp calls) does not call fsync(). FYI, the history here is somewhat complicated and “ugly, but in general, if the system were going specifically trying to flush data, it woul

Reply to Standalone Watch App Woes
More Context: Xcode 26.1.1 New standalone watchOS project - default settings. There is a project with two targets - an iOS target and a watchOS target. The iOS target is at default - no code added or taken away all certificates and profiles point to my distribution certificate and provisioning. The bundle_id's seem good. The Project and ios share a bundle id of com.myteam.myapp The watchOS bundle id is com.myteam.myapp.watchkitapp There are identifiers for both in App Store Connect. The app compiles and runs on the simulator with no errors, all sizes, all languages. I do not have a watch connected to the account, but the code has been tested and I can't imagine that the lack of a physical device is causing the problem The scheme has the 3 archs in top to botton project, ios, watchOS - all marked to do everything they can and everything I see is marked to release.
