Hello. we are looking in adding an additional verification method as part of our in app provisioning to apple wallet. the method is called app to app verification method where basically when the customer adds their card (debit or credit) on apple wallet they can be verified through a third party app. does apple support this? where can i find any material related to this?

When I use the method provided in the document https://developer.apple.com/documentation/passkit/pkpasslibrary/activate(_:activationdata:completion:)?changes=_1__4,_1__4 to verify a card that has been added to Apple Wallet, I get an error code: 500 unknown error How can I troubleshoot the problem?

Error: RoomCaptureSession.CaptureError.exceedSceneSizeLimit Apple Documentation Explanation: An error that indicates when the scene size grows past the framework’s limitations. Issue: This error is popping up in my iPhone 14 Pro (128 GB) after a few roomplan scans are done. This error shows up even if the room size is small. It occurs immediately after I start the RoomCaptureSession after the relocalisation of previous AR session (in world tracking configuration). I am having trouble understanding exactly why this error shows and how to debug/solve it. Does anyone have any idea on how to approach to this issue?

Hello Apple Team, We’re building a CloudKit-enabled Core Data app and would like clarification on the behavior and performance characteristics of Binary Data attributes with “Allows External Storage” enabled when used with NSPersistentCloudKitContainer. Initially, we tried storing image files manually on disk and only saving the metadata (file URLs, dimensions, etc.) in Core Data. While this approach reduced the size of the Core Data store, it introduced instability after app updates and broke sync between devices. We would prefer to use the official Apple-recommended method and have Core Data manage image storage and CloudKit syncing natively. Specifically, we’d appreciate guidance on the following: When a Binary Data attribute is marked as “Allows External Storage”, large image files are stored as separate files on device rather than inline in the SQLite store. How effective is this mechanism in keeping the Core Data store size small on device? Are there any recommended size thresholds or

Hi all, I obtained a D-U-N-S number, confirmed that it's available for lookup, and submitted a request to upgrade to an Organization account 12 days ago. I then followed up 3 days ago. Still haven't received a response. Does anyone know if there's anything I need to do to get a response to these inquiries? Only reason I'm upgrading to Organization account is so that multiple developers can sign debug builds for physical iPhone devices so they can collaborate on my project.

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

Hello Apple Developer Community, I'm experiencing an issue with file download functionality in the iOS Simulator after updating to Xcode 26 RC (Build 17A321). Issue Description: When attempting to download files in the iOS Simulator via Safari, the download prompt appears correctly, but after tapping the 'Download' button, files are not being saved to the Files app. The download appears to do nothing with no error message, no indication of failure, but the file simply doesn't appear in Downloads or anywhere in the Files app. Environment: Xcode Version: 26.0 RC (17A321) iOS Simulator Version: 26.0 RC (23A339) Device Simulated: iPhone Air Steps to Reproduce: Open Safari in the iOS Simulator Navigate to a downloadable file (PDF, ZIP, etc.) Tap to initiate download Download prompt appears as expected Tap the 'Download' button Check the Files app → Downloads folder (empty) Expected Behavior: Files should download normally as they do on physical devices and as they did in previous Xcode versions. Actual Be

navigator.permissions.query -> permissionStatus.onchange is Supposed to listen to the event of a change in permissions in the browser settings. This works for all browsers, but in Safari for iOS and MacOS this seems to be broken in the currently recent versions 17.x Example: navigator.permissions.query({ name: 'notifications' }).then((permissionStatus) => { permissions = permissionStatus.state; // this value gets set correctly permissionStatus.onchange = () => { // This will not get executed when permissions have been changed // within the safari settings app, or iOS Settings for PWA or Safari }; }); Can someone from Apple's Webkit Team please comment on this? Thank you. T.
