Hi, Is it possible for a macOS (or iOS/ipadOS) app to communicate with a CCID-compliant reader using the CCID interface (i.e., directly sending the PC_TO_RDR_* messages) instead of using the CryptoTokenKit API? Apple's CCID driver (/System/Library/CryptoTokenKit/usbsmartcardreaderd.slotd) seems to support all the PC_TO_RDR and RDR_TO_PC messages: https://blog.apdu.fr/posts/2023/11/apple-own-ccid-driver-in-sonoma/#enable-my-ccid-driver The background for this question is that we develop smartcard products and we'd like to use the finer grained settings provided by the CCID specification for testing/demo purposes. Thank you.

While developing our driver, we've noticed that the *.ips report that contains the stack trace of the crash is not always generated. To be clear, you're talking about DEXT level users space crashes, NOT kernel panics? I've assumed below that you're dealing with standard crashes, but please let me know if I've misunderstood. I'm wondering why this report may not get generated. So, the first step here is to figure out what actually happened, which means digging through the console log. In general, there are multiple components tracking (notably, launchd) any system component (including DEXTs) and they'll be notified of your process's death, including how/why it died. If you're on development hardware then there are some tips in Your Friend the System Log that can be useful for quickly getting at this sort of data; however, I'd generally trigger a sysdiagnose and use that console archive. The big advantage of the sysdiagnose is that you capture everything, which means you're not going to miss data if so

I have an app with SwiftData and CloudKit sync enabled, it was working fine but I recently noticed that the sync with CloudKit is not working anymore. All the changes are persisted locally just fine. When running in simulator (iOS 26/iPhone 17 Pro) I get the following error in the console: CoreData+CloudKit: -[NSCloudKitMirroringDelegate recoverFromError:](2317): - Attempting recovery from error: Error Domain=NSCocoaErrorDomain Code=134421 Export encountered an unhandled exception while analyzing history in the store. UserInfo={NSLocalizedFailureReason=Export encountered an unhandled exception while analyzing history in the store., NSUnderlyingException=-[NSEntityDescription objectID]: unrecognized selector sent to instance 0x60000351aec0} I already tried Reseting the environment back to production in CloudKit and Erasing all Contents and Settings in the simulator but I keep getting the same error. Is there something else I can do to fix this?
Hi, I'm trying to add an extension to my app on iOS 26. I've followed the instructions on https://developer.apple.com/documentation/extensionfoundation/adding-support-for-app-extensions-to-your-app and made it as far as being able to launch the extension: let monitor = try await AppExtensionPoint.Monitor(appExtensionPoint: .localWebServerExtension) currentIdentity = monitor.identities.first if let currentIdentity = currentIdentity { let myConfig = AppExtensionProcess.Configuration(appExtensionIdentity: currentIdentity, onInterruption: { NSLog(extension was terminated) }) myProcess = try await AppExtensionProcess(configuration: myConfig) myConnection = try myProcess?.makeXPCConnection() } None of these calls throw, and when I examine myProcess from inside that code, it seems to be normal (there's a pid, for example). Yet the code inside my extension seems to not be executed: breakpoints are not triggered, NSLog() calls do not appear on the console. The onInterruption() callback is also not triggered, or at lea
I have a working AlarmKit app, but I've noticed that after any iOS update (e.g. the 26.0.1 update from a few days ago), my scheduled alarms seem to lose their UI strings, so instead of the Stop button saying Stop, it says alarm_ui_stop_button (which is my localization key for the button text). If I delete the alarm and re-add it, then it works again... until the next software update. It seems like OS updates are interfering with the link between scheduled alarms and app localization strings, which I believe are dynamically looked up at alarm time (not at configuration time). I am settings the strings in the standard way like this: AlarmManager.AlarmConfiguration( schedule: .fixed(date), attributes: AlarmAttributes( presentation: AlarmPresentation( alert: AlarmPresentation.Alert( title: alarm_ui_title, stopButton: .init(text: alarm_ui_stop_button, textColor: .yellow, systemImageName: xmark) ) ), metadata: SDAlarmMetadata(title: title, subtitle: subtitle), tintColor: .yellow ), sound: .default ) Has an

Hi, Since iOS 26 (and any other apple system with a 26 version) there is a very weird behavior in the whole apple ecosystem (iOS, iPadOS, macOS and visionOS). I'm self-hosting a web project called mempool (https://github.com/Retropex/mempool). This project is entirely self-hosted on my own infrastructure, so I have advanced control to be sure it's just not an anti-DDoS feature that makes the bug happen. So the bug is once I visit my website, for example this page (https://mempool.guide/tx/d86192252a6631831e55f814aea901e65407b6dbda77e1abdea8ec27861e9682) the OS will lose the ability to connect to the underlying IP of the domain (mempool.guide) but the issue seems to affect only the HTTPS/HTTP port (443/80). The issue is system wide, not only is Safari. For exemple I have another domain that resolve to the same IP (haf.ovh) and if this link above trigger the bug then I will also lose the ability to connect to https://haf.ovh A temporary fix that I have is that if I turn off wifi/cellular then
One more reason why I never use safari. Its devtool's debugger is clunky and lack of some modern WebAPIs and buggy APIs make my life as a developer very hard. I genuinely hate the Developer Experience. Chome and Firefox are so easy to work with. I hope some day Apple focuses on their devtools and software products

Once, the App Store empowered indie creators - small teams could launch great apps Nothing has changed in that respect. There are more opportunities now for people to build low-quality apps by using low-quality, cross-platform frameworks and tools. But people are still able to launch great apps with discipline, intelligence, and hard work. and find users easily This part has changed. There are lots more apps to choose from, a radically different marketplace, and different user expectations. It now takes more work and more time to find users. But in 2025, that era feels long gone, with algorithms, big players, and pay-to-win discoverability reshaping everything. Many things have changed over the past 17 years. Is there still a real chance for indie iOS developers today, or has Apple’s evolving ecosystem made independent success nearly impossible? Many people are having success. They're just focused on their products and providing a great experience for their customers. Posting content on social media

Pretty much as per the title and I suspect I know the answer. Given that Foundation Models run on device, is it possible to use Foundation Models framework inside of a DeviceActivityReport? I've been tinkering with it, and all I get is errors and Sandbox restrictions. Am I missing something? Seems like a missed trick to utilise on device AI/ML with other frameworks.
Dear Apple engineers, We have developed a DriverKit (DEXT) driver for an HBA RAID controller. The RAID controller is connected to hosts through Thunderbolt (PCIe port of the Thunderbolt controller). We do plug/unplug tests to verify the developed driver. The test always fails in about 100 cycles with a MacOS crash (panic). The panic contains “LLC Bus error (Unavailable) from cpu0: FAR=0xa40100008 LLC_ERR_STS/ADR/INF=0x80/0x300480a40100008/0x1400000005 addr=0xa40100008 cmd=0x18(ACC_CIFL2C_CMD_RD_LD: request for load miss in E or S state)” At first we assumed that the issue is with hardware. But we did this test on different hosts (MacMini M3 and M4) with different units of our device. The error points to the same physical address FAR=0xa40100008 even if the hosts are different. The 2 full panic logs are attached (one for M4, another one for M3 host). Could you share your understanding of the crash and give any hints on how we can fix it? Please let us know if you need any additional data. Thank you M3

Thanks for following up, and apologies for the delay-- this slipped past me. Here’s a repro asset I wrote that you can test directly: https://github.com/alexchuber/Assets/raw/refs/heads/main/Repros/triangleNegScale.usdz For additional reference, here's the USDA content of the asset (material omitted for clarity): #usda 1.0 ( defaultPrim = Root metersPerUnit = 1 upAxis = Y ) def Xform Root { def Mesh Triangle { matrix4d xformOp:transform = ( (-1, 0, 0, 0), (0, 1, 0, 0), (0, 0, 1, 0), (0, 0, 0, 1) ) uniform token[] xformOpOrder = [xformOp:transform] int[] faceVertexCounts = [3] int[] faceVertexIndices = [0, 1, 2] normal3f[] normals = [(0, 0, 1), (0, 0, 1), (0, 0, 1)] ( interpolation = vertex ) point3f[] points = [(0, 0, 0), (1, 0, 0), (0, 1, 0)] uniform token subdivisionScheme = none } } The steps to reproduce are just: Add the asset to a new Reality Composer Pro scene. Open the same asset in QuickLook on iOS/macOS. Compare the facing direction in both views. You should see that the triangles appear to have opp

Yeah! It's working! I have a macOS 26.0 host. In UTM I have a macOS 15.7 guest with a Provisioning UUID that has never been added as a device in the developer portal. In my developer account I added a new device with the guest VM's UUID. It's the longer style with lowercase hex digits. I then edited my existing manual provisioning profile with the new device. In Xcode (26.1 beta 2) I changed my app's signing from automatic to manual and referenced the updated provisioning profile. I built the app and copied the new app to a share I use for the VM. I ran the VM and tried to run the updated app. It failed. I missed one step that maybe some others might miss. In Xcode, go to Settings, Apple Accounts. Select your account. Then select your team. Then click on Download Manual Profiles. Once I did that, I rebuilt the app with the now properly updated provisioning profile and recopied the app to the share. And now the app runs in the guest VM! Key steps for those that are not starting from scratch:

I was asked to follow up on FB19449747 after this was supposedly fixed, so I did. I can't see a DriverKit PCI Transport (development) entitlement in the list of available Capabilities. Huh. Can you double-check on the portal just to be sure? I've checked on three different teams I have access to, and all of them are showing it. A few things to note: It's actually called DriverKit PCI (development), simply to keep the name length a bit more manageable. I just noticed that it doesn't currently include the extra Development only. Learn more Provisioning support required. label on the portal (I'm working on fixing that). I also noticed that it's offering iOS as a platform, which turned out to be one example of a much broader bug (r.162380702). It turns out that several DriverKit entitlements also include extra platforms, which means they can be included in targets they should not be included with. I don't think including them will actually cause any problems (macOS will just ignore them), but it's definitely some
