HID Device Access / Mode Switch
I might be trying to achieve the impossible here, but if there's another way to go about it any advice would be appreciated. I've got an older Linux application that reflashes firmware on a connected USB HID device that I'm trying to port to macOS. Essentially the device starts as an HID interface (0x03/0x01/0x01) but to update firmware receives a simple control payload and then restarts and connects as a different (non-HID) device. However I can't open the HID device at all, I'm guessing this is some sort of permission error (SIP?). AppleUSBHostUserClient::openGated: failed to open IOUSBHostDevice... provider is already opened for exclusive access by AppleUSB20Hub hid_open_path: failed to open IOHIDDevice from mach entry: (0xE00002E2) not permitted AppleUSBXHCICommandRing::setAddress: completed with result code 4 AppleUSBHostPort::createDevice: failed to create device (0xe00002bc) AppleUSBIORequest ... transaction error ... 0xe00002ed Is there any way at all to do this on macOS? Interestingly if you run

Reply to Xcode 26.x Frequently Freezes During Breakpoint Debugging with Simulator
@Z_L_Z, @G-null, I want to be clear about what’s going upthread. The folks having this issue are using Rosetta to run the simulator. In my earlier post I made it clear that that’s not a supported configuration. So: If you’re also using Rosetta to run the simulator, I recommend that you stop doing that and see if the problem persists. If you’re not using Rosetta to run the simulator, I recommend that you start a new thread here on the forums with the details of your issue. That’ll ensure that folks reading your thread don’t get distracted by the Rosetta history in this thread. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com

HCE not working in Testflight Builds
We have enabled the Host Card Emulation (HCE) capability for our app and successfully implemented and tested the functionality during development. When running the app directly from Xcode, HCE-related flows work as expected. However, we are observing different behavior in the distributed build. In particular, the following check consistently evaluates to false: guard await CardSession.isEligible else { return } After distributing the app via TestFlight, HCE functionality is not available for external testers. The CardSession.isEligible property always returns false, even when tested on supported devices and in supported regions. We are using the same bundle identifier for both development and distribution builds, and the provisioning profiles include the required capability. Could you please clarify the following: Are there any additional entitlements, approvals, or configuration steps required for HCE to function in TestFlight or distribution builds? Are there known region, device, or account-relate

Reply to How to install and manage Network Extension in case of GUI-less application?
Thank you for the help! Our cross-platform DLP solution is deployed via a standard .pkg installer and must support macOS 11 and later. The installer sets up a LaunchAgent which is responsibe for system monitoring and launching container app (which bundles NE) when necessary. Once activated, the Network Extension communicates with independently deployed LaunchDaemon via XPC (https://developer.apple.com/forums/thread/820631). To avoid confusing users with unnecessary UI, this container app must run in the background without a Dock icon. Is it officially supported to configure the Network Extension's containing .app as a background-only application by setting LSUIElement = YES in its Info.plist? Is it supported for our independently deployed LaunchAgent to programmatically launch this background-only .app? (Note: I understand that without an MDM profile, the user will still be prompted to manually approve the system extension in System Preferences/Settings) Thanks!

Reply to Embedded Collection View in SwiftUI offset issue
I cloned your repo and reproduced the issue on page 3 (index 2). Three things remain in your layout that together keep the offset misaligned during rotation. 1. estimatedItemSize in prepare() enables self-sizing mode Your prepare() sets estimatedItemSize = collectionView.bounds.size on every pass. This puts UICollectionViewFlowLayout into self-sizing mode, which changes how the flow layout processes invalidation internally — even though shouldInvalidateLayout(forPreferredLayoutAttributes:…) returns false. In self-sizing mode, the flow layout can trigger additional invalidation passes during a single bounds change. When invalidationContext(forBoundsChange:) runs more than once before the content offset is actually applied, the adjustment compounds. The error is proportional to the page index, which is why page 0 always looks fine, page 1 sometimes slips, and page 2+ consistently shows two pages. The fix is to leave estimatedItemSize at .zero (already set in init). Your layout computes all cel

Store Kit 2 iOS system purchase confirmation dialog not consistent.
I'm running into an issue where it appears the product transaction is being cached and not showing a new iOS system popup dialog to confirm the purchase. This is affecting testing, and I need a solution to have iOS issue a new purchase transaction every time. Here's what happens, I call the following which always succeeds. try await product.purchase(options: [.appAccountToken(appToken)]) I'm signed into a developer sandbox account with a resubscribe every 5 minutes. After cancelling a subscription, I attempt to resubscribe using the same code as above. Frequently, the code executes without iOS showing the popup system dialog to confirm the purchaser. After waiting a period of time, iOS then resets itself and allows me to purchase again. What I want is an option the forces the iOS system confirm purchase dialog to show up every time the code executes. How do I fix this? iOs 26.4.1, iPhone 17 Pro.

Reply to CKRecordZone deleted when second user accepts zone-wide CKShare
Thanks for sharing the details of your sharing flow, and nice to know that you made great progress. To your following question: Is the programmatic CKFetchShareMetadataOperation → container.accept(metadata) path fully supported for zone-wide CKShare(recordZoneID:) shares? Or does zone-wide sharing require the system-level authentication that happens when a user taps the CKShare.url directly (triggering userDidAcceptCloudKitShareWith)? Yes, the programmatic path, which CloudKit folks call in-process share acceptance, is fully supported. The user interaction is not required. Given that, I don't see the flow you described has anything wrong. However, after 20+ zone create/delete cycles during debugging, the container now appears to be in a degraded state — new zones (even with completely fresh names never used before) are deleted by the server within seconds of creation, on a single device with no other apps running. I'm waiting for the container to stabilize (tombstone TTL) before further testing. Rese

Reply to Apple Watch companion app keeps uninstalling
Would you mind to check if the Show App on Apple Wwatch in the Watch app in your iPhone is (unintentionally) off? You can find the setting with the following steps: Launching the Watch app in your iPhone. Select the My Watch tab and find your app in the Installed On Apple Watch section. Tap your app to see the setting. Assuming that your watchOS app is not watch-only, I am also curious if your watchOS app's Info.plist has the WKRunsIndependentlyOfCompanionApp key and its value is YES.

Reply to “In-App Purchases and Subscriptions” section on the version page not showing
@Gascad Your first subscription must be submitted with a new app version. Create your subscription, then select it from the app’s In-App Purchases and Subscriptions section on the version page before submitting the version to App Review. - However, I don't see a way to get to the in-app purchases and subscriptions part of the Version Page. When I see online videos they show a + button for the new versions but I don't see those for my app. As mentioned above, the In-App Purchases and Subscriptions section only appears when you have one or more products with the Ready to Submit status. For more information, see In-App Purchase statuses. Check the status of your In-App Purchases you wish to submit for review, if their status is Missing Metadata,complete any missing information. If their status is Waiting for Review or In Review, there is nothing to do. You already submitted them for review.
