Reply to Inquiry Regarding USB Network Connectivity Between an iPad (Wi‑Fi Model) and an Embedded Linux Device
My understanding is that your accessory is presenting a network interface to iOS much like, say, an USB Ethernet dongle would. In that case I’d expect iOS to assign IP addresses to that interface as long as the interface claims that it’s up. You can prototype this with an USB Ethernet dongle: Connect the dongle via Ethernet to the Internet. And then connect it to iOS. Verify that iOS has network connectivity over the Ethernet. Disconnect it from iOS. Disconnect the Ethernet dongle from the Internet, but leave it connected to your switch so that the link status stays up. Reconnect it to iOS. You should see iOS bring up the interface with link-local IPv4 [1] and IPv6 addresses. Any app running on iOS should be able to communicate over that interface. For example, if you have a configure like this: iPhone | USB Ethernet | ----+----------------+--------------- isolated Ethernet | Mac | ---------------------+--------------- Wi-Fi to Internet Safari on the iPhone should be able to connect to a web

IPhone fails to connect with Xcode in presence of multiple WebContentFilters
I am facing an intermittent problem where iPhones are failing to pair/connect with Xcode under Xcode -> Windows -> Devices and Simulators. This happens when more than one web content filters are present, for instance, I have my web content filter (FilterSockets true, FilterGrade Firewall) and there is also Sentinel One web content filter with same configuration. Note: We are not blocking any flow from remoted / remotepairingd / core device service / MDRemoteServiceSupport etc processes. But they do get paused and resumed at times for our internal traffic verification logic. So, we are trying to understand what impact our content filter may be having on this iPhone Pairing?? If we stop either one of the filters the problem goes away. I have tracked the network traffic to the phone, and it seems to be using a ethernet interface (en5/en10) over the USB-C cable. I can see endpoints like this: localEndpoint = fe80::7:afff:fea1:edb8%en5.54442 remoteEndpoint = fe80::7:afff:fea1:ed47%

Request for Official Draggable FCPXML Structure Specification for Workflow Extensions – Needed for Subtitle/Caption Generation Tools
Hi Apple Developer Forums and Final Cut Pro team, I am developing a Final Cut Pro Workflow Extension focused on speech-to-text / subtitle recognition and generation. The extension runs inside Final Cut Pro, analyzes clips, generates accurate subtitles (often hundreds of individual elements), and allows users to drag the generated subtitles directly back into the FCP timeline as a clean, editable Compound Clip or Storyline. We are implementing this drag-and-drop functionality using the official pasteboard mechanism (com.apple.finalcutpro.xml and versioned types such as com.apple.finalcutpro.xml.v1-10). While the high-level documentation is helpful: Supporting Drag and Drop for Data Sent to Final Cut Pro FCPXML Reference Designing Workflow Extensions There is still no detailed public specification for the exact internal XML structure that Final Cut Pro expects for a drag operation to reliably result in a usable Compound Clip (or direct Storyline insertion), especiall

UITextView cursor sometimes jumps up when pressing arrow down key and setting typingAttributes
My app uses TextKit 1 and unfortunately still cannot migrate to TextKit 2 because of some bugs (for instance in FB17103305 I show how NSTextView.shouldDrawInsertionPoint has no effect, but I opened that feedback exactly one year ago and it still has no answer). Unfortunately TextKit 1 has another bug which causes the text cursor to jump unpredictably up or down when pressing the arrow keys and setting UITextView.typingAttributes. Run the code below on iPhone 17 Pro Max Simulator. Scroll the text down until you see “Header 2”. Place the text cursor after “# “. Press the arrow down key twice to move the cursor two lines down. The cursor moves to the top of the view instead. Continuing to press the arrow keys up and down results in the cursor sometimes moving as expected, other times jumping around wildly. Does anyone know a workaround? I created FB22382453. class TextView: UITextView, UITextViewDelegate { override func awakeFromNib() { let _ = layoutManager delegate = self let header = textAtt

Reply to Sporadic crash in xzm_main_malloc_zone_init_range_groups when spawning large binaries (macOS 26.3.1)
Thanks Quinn, that was exactly the right pointer. We traced through the disassembly of xzm_main_malloc_zone_init_range_groups on macOS 26.3.1 and correlated it with the open source in rel/libmalloc-792 (xzone_segment.c:1210-1250). Here's what we found: The CONFIG_MACOS_RANGES path computes: ptr_reservation_size = XZM_RANGE_SEPARATION + XZM_POINTER_RANGE_SIZE + XZM_RANGE_SEPARATION = 4G + 16G + 4G = 24 GiB ptr_start = 16GiB + (entropy % 736) * 32MiB It then calls mach_vm_map with VM_FLAGS_FIXED for 24 GiB at ptr_start. The 736 granules cover [16 GiB, 39 GiB), ensuring the reservation fits under the 63 GiB commpage limit. Why dylibs land above 16 GiB: The binary is a Chromium component-build test binary (browser_tests) that loads 516 Chromium dylibs plus system libraries (1543 images total). The main executable alone consumes 5.54 GiB of VA (4 GiB __PAGEZERO, 517 MiB __TEXT, 1.04 GiB __LINKEDIT). The 516 Chromium dylibs add another 10.19 GiB of aggregate VM (2.26 GiB __TEXT, 3.86 GiB __LINKEDI

AVKit crash when rendering AVPlayerView controls — macOS 26.4 regression
Description Our app, Octory, allows users to create onboarding and communication workflows composed of slides containing various UI components, including embedded video players powered by AVPlayerView. Since macOS 26.4 Beta, the app crashes at launch whenever a workflow contains a video component. Workflows without video components load and render without issue, which points to a regression in AVKit's player control rendering pipeline. As anyone seen similar behaviour when using AVKit or is it something we do not do properly? Expected Behavior The app opens and renders the workflow, including the embedded video component. Actual Behavior The app briefly launches and immediately crashes with SIGABRT on the main thread. Crash Analysis Key takeaways for anyone investigating: Root cause — abort() inside NSImageSymbolConfiguration The crash occurs entirely within Apple frameworks, with no third-party code in the faulting call chain (aside from the app's entry point). The sequence is: AVPlayerItem finishes loading

Why doesnt the Media Manager tell which devices have the required proportions?
When launching an app, AppStore Connect has some very specific requirements to the media (screenshots) used for the store listing. Right now the primary screenshots requires a 6.5 inch size. This is fine, of course, but why doesnt it list which iphones has this size, so I dont have to google my way to this answer? Its such a small thing, but would help so much

Developer Program payment never processed, support does not reply
Hi everyone, I am an iOS developer from Ecuador and I am writing to ask if there's any way to fix my issue. After some initial struggling with my phone number not being able to receive Apple verification messages, I was able to register an Apple ID and use that Apple ID to enroll into the Apple Developer Program. Currently, I am stuck at the step of paying the subscription fee. When I try to pay for the 99$ enrollment fee, I receive an Order Acknowledgement e-mail from Apple but the payment is never processed. I have tried with multiple debit cards: 2 times with my main crypto debit card emitted from a Hong Kong bank 1 time with a debit card emitted from a local Ecuadorian bank 1 time with a debit card emitted from a US bank In all these cases the result is the same: the same order acknowledgement e-mail but nothing more happens. I even tried asking the support via e-mail (the only method that is supported in my country), but no one replies. Does anyone have any tip on how to overcome this situation?

Rejected under Guideline 1.1.1 (Objectionable Content) — car notification app, looking for advice
Hi everyone, I recently got rejected under Guideline 1.1.1 - Safety - Objectionable Content and I'm struggling to understand how my app falls under this category. Looking for advice from anyone who's dealt with similar rejections. What the app does: AutoSignal is a vehicle notification app designed for the Bulgarian market. It solves a very common real-world problem - needing to contact a car owner when their vehicle is double-parked, blocking you in, has its lights left on, or has been hit/damaged while parked. The core flow is: A user scans a license plate using their phone camera If the car owner is registered in the app, they receive an anonymous push notification (e.g., Your car with plate XX 1234 XX is blocking someone or Your lights are on) The car owner can then take action Users can also report vehicle damage cases with temporary witness notes that auto-expire after 7 days. Why I believe it doesn't violate 1.1.1: The app does not expose any personal information. Notifications are fully anony
