Reply to System Panic with IOUserSCSIParallelInterfaceController during Dispatch Queue Configuration
Hi Kevin, During the implementation of batch task buffer mapping, we observed an inconsistency between API return values and actual memory addresses, which leads to an immediate system Panic (Kernel Data Abort). Inside the implementation of UserMapBundledParallelTaskCommandAndResponseBuffers, we performed the following operations on the Response Buffer: We invoked CreateMapping(0, 0, 0, 0, 0, &ivars->fResponseMap) on the provided parallelResponseIOMemoryDescriptor. CreateMapping returns kIOReturnSuccess, and the resulting ivars->fResponseMap object pointer is non-null. However, a subsequent call to ivars->fResponseMap->GetAddress() returns NULL (0x0). After the DEXT returns from UserMapBundledParallelTaskCommandAndResponseBuffers with this NULL address, the system immediately triggers a Panic when the kernel attempts to process subsequent discovery commands (e.g., Inquiry). Panic Type: Kernel data abort Fault Address (FAR): 0x0000000000000000 Exception Class (ESR): 0x96000006 (Translation Faul

Frameworks and library dependencies
I have a framework, which depends on a library (GPGME) to do its actual encryption. As a consequence of using this external library, there are header files which have GPGME types in them... @interface E3Gpgme : NSObject ... /***************************************************************************** |* Call GPGME to sign *****************************************************************************/ - (int) signWithMode:(gpgme_sig_mode_t)mode userId:(NSString *)signingKeyOrEmail srcStream:(E3Stream *)src dstStream:(E3Stream *)dst error:(NSError **)error; ... @end . This means the E3Gpgme class header file has to #import to get those type definitions. That is then proving problematic because the framework modularisation fails, with obviously not being a part of the framework, so the project refuses to build. I can see a few ways around this: Just don't run the modularisation check. That doesn't sound like a fantastic option import the GPGME headers (there's only 2) into t

Reply to App Startup with Debugger in Xcode 26 is slow
I have attempted to use Xcode 26.2 with a device running iOS 26.2, same configuration as in the original post, and I don't find the user experience to have improved one bit: app startup takes ages before I even see my UIWindow and UIViewController on screen starting without debugger and attaching afterwards causes the app to lag horribly, which was not a problem originally when I only started to try Xcode 26.0

Showing 3D/AR content on multiple pages in iOS with RealityView
Hi. I'm trying to show 3D or AR content in multiple pages on an iOS app but I have found that if a RealityView is used earlier in a flow then future uses will never display the camera feed, even if those earlier uses do not use any spatial tracking. For example, in the following simplified view, the second page realityView will not display the camera feed even though the first view does not use it not start a tracking session. struct ContentView: View { var body: some View { NavigationStack { VStack { RealityView { content in content.camera = .virtual // showing model skipped for brevity } NavigationLink(Second Page) { RealityView { content in content.camera = .spatialTracking } } } } } } What is the way around this so that 3D content can be displayed in multiple places in the app without preventing AR content from working? I have also found the same problem when wrapping an ARView for use in SwiftUI.

MacOS(Apple Silicon) IOKit driver for FPGA DMA transmission, kernel panic.
MacOS(Apple Silicon) IOKit driver for FPGA DMA transmission, kernel panic. Hardware and software configuration: MAC mini M1 2020 16GB, macOS Ventura 13.0 or 13.7.8 FPGA device capability: 64-bit Complete description: We've developed a DMA driver for PCIe devices (FPGA) based on IOKit. The driver can start normally through kextload, and the bar mapping, DMA registers, etc. are all correct. I am testing DMA data transmission, but a kernel panic has occurred. The specific content of the panic is as follows: {bug_type:210,timestamp:2026-01-28 14:35:30.00 +0800,os_version:macOS 13.0 (22A380),roots_installed:0,incident_id:61C9B820-8D1B-4E75-A4EB-10DC2558FA75} { build : macOS 13.0 (22A380), product : Macmini9,1, socId : 0x00008103, kernel : Darwin Kernel Version 22.1.0: Sun Oct 9 20:14:30 PDT 2022; root:xnu-8792.41.9~2/RELEASE_ARM64_T8103, incident : 61C9B820-8D1B-4E75-A4EB-10DC2558FA75, crashReporterKey : 6435F6BD-4138-412A-5142-83DD7E5B4F61, date : 2026-01-28 14:35:30.16 +0800, panicString : panic(cpu 0 c

iOS 26: hidesSharedBackground does not work for backBarButtonItem
What works let backButton = UIBarButtonItem(title: , style: .plain, target: nil, action: nil) backButton.hidesSharedBackground = true self.navigationItem.rightBarButtonItem = backButton // or self.navigationItem.leftBarButtonItem = backButton What doesn't work let backButton = UIBarButtonItem(title: , style: .plain, target: nil, action: nil) backButton.hidesSharedBackground = true self.navigationItem.backBarButtonItem = backButton I've tried setting this property on all possible permutations and combinations e.g. Inside navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) and pushViewController(_ viewController: UIViewController, animated: Bool) of a custom UINavigationController to make sure. Expected vs Actual behavior Setting hidesSharedBackground = true should remove the glass background from both regular bar button items and back bar button items but it has no effect on backBarButtonItem.

Reply to Custom NSWindow styleMask behavior changed/broken resulting in unresizable or non-responsive windows in macOS Tahoe 26.3 RC
@Frameworks Engineer We also encountered an issue with transparent NSWindows on 26.3 RC (FB21879511). On 26.3 RC, mouse events are intercepted by the entire transparent window rather than only the opaque regions. As a result, any third-party app that uses full-screen overlay windows blocks system interactions while the overlay is present on the screen.

Reply to Virtual Machine UDID Changes in macOS 15: Looking for Guidance on Development Workflow
[quote='874968022, Shay39, /thread/810932?answerId=874968022#874968022, /profile/Shay39'] I believe the behavior we're seeing is explained in the documentation … [/quote] That’s my interpretation as well, but I’m still not 100% certain that it matches the behaviour that ArthurValiev is reporting up thread. I have a reminder to spend some more time digging into this, but I haven’t yet had a chance. [quote='874968022, Shay39, /thread/810932?answerId=874968022#874968022, /profile/Shay39'] as it's currently the only practical method I'm aware of for preserving UDIDs. [/quote] It’s certainly a useful option, yes. Another option is to start with a template VM, then clone it twice [1] for each ‘runner’ Mac, start each one, and then stop it cleanly. Each one should pick up a new provisioning UDID during its startup sequence and you can then assign that provisioning UDID to your account. This is quite fiddly to manage, and it won’t work for organisations that have a large number of runners, but it’s an option worth ex

App rejected under guideline 2.5.1 - Private API _SecCertificateIsValid flagged but not present in binary
App is repeatedly rejected under Guideline 2.5.1 for referencing the private API:_SecCertificateIsValid Reported custom framework CommonLibrary.framework. The SDK is written in Objective-C and uses only public Security APIs. It does not use any deprecated APIs. We have verified the framework binary using nm, otool, and strings, and _SecCertificateIsValid does not appear in exported or hidden symbols. Bitcode is disabled, dead-code stripping is enabled, and the Release build uses -Os. Despite this, App Store Connect continues to detect _SecCertificateIsValid. We have attached herewith screenshots of our analysis for the reference. Can Apple’s server-side analysis or Security.framework internals still surface _SecCertificateIsValid? Is there a recommended way for SDK authors to prevent this symbol from being flagged?

Reply to iOS UDP transmission always experiences packet loss
I’d like to clarify my understanding of your issue: Your app works in general. But on some small fraction of iOS devices it doesn’t work at all. And the user can fix that by resetting the network settings. Is that right?
