Overview

Basic information: The issuer has implemented the feature to active Apple Card via URL Verification. The feature implemented by issuer is supported both in the APP and Clips. When Apple queries the activation method from UnionPay, UnionPay returns the "URL" activation method to Apple. Additionally, the apple-app-site-association file has been correctly deployed, and the configuration for Universal Links has been completed. Both the APP and Clips have undergone testing for Universal Link calls. The desired experiece is that when the APP is installed, Apple Wallet launches the APP, and the user completes the activation within the APP, and if the APP is not installed, Apple Wallet calls Clips, and the user completes the activation in Clips. Problem description: Under iOS 17 and iOS 18, when triggering Apple Pay card activation, the APP or Clips can be called as expected, and the activation can be completed well. However, Under iOS 26, regardless of whether the APP is installed, under the same circumstances, an internal browser within Apple Wallet opens to access the H5 page corresponding to the URL, instead of redirecting to the APP or Clips. Please assist in confirming whether this is a new feature of iOS 26 and how the same user experience can be achieved.

context:Explore low-latency video encoding with VideoToolbox https://developer.apple.com/videos/play/wwdc2021/10158/ I see above post said HEVC VideoToolbox can support SVC, temporal layering of streams in low-latency mode with all P frames. my question is that Does HEVC VideoToolbox support temporal layering of streams with B-frames ?? thanks

When an alarm is scheduled for 00:00, the system displays the fullscreen alarm interface twice. After the second fullscreen view appears, both the “Stop” and “Snooze” buttons become unresponsive, but using the physical button (volume or power button) can dismiss the alarm and correctly trigger the StopIntent. This behavior occurs consistently (100%), whether the system time is set normally or manually adjusted before the alarm triggers. Environment: Device: iPhone 14 Pro Max iOS Version: 26.0 Reproducibility: 100%

We are using three column split view as root of our app and wants to hide the supplementary column alone in some cases and behaves like two column split view. With the existing apis we are unable to achieve this since it hides primary column as well and not giving expected results. .hide(.supplementary) setViewController(nil, for: .supplementary) But seen this behavior in Native Notes app when using the View as List and Gallery option. is there any way to achieve this with maintaining three column split view itself ?

Hi, we've developed an app for Vision Pro that utilises the GroupActivitites SDK to provide shared experiences for our users. Remote Participation works great, but we can't get nearby sharing to work. The behaviour we're observing: User 1 engages share sheet from Volume, 2nd Vision Pro is visible. User 1 starts nearby sharing Session initialisation runs for approx. 30 seconds, then fails Sometimes, the nearby participant doesn't show up at all after the initialisation has failed once. As stated in the Configure your visionOS app for sharing with people nearby article, we didn't make any changes to our implementation to support nearby sharing. Any help would be greatly appreciated. Kind regards, David

Is there sample code on how to use VTFrameProcessorOpticalFlow?

Hi everyone, We had developed an iOS Application in Flutter and built it using XCode 26.0.1. We're unable to install this application in iOS 18.7. Below are the details, ➡️ Development Environment: 🔹 Flutter: 3.32.2 ➡️ Build Environment: 🔹 Xcode: 26.0.1 🔹 Build system: Flutter → flutter build ios --release, then opened in Xcode for signing ➡️ Device models tested: 🔹 iPhone (iOS 15.8.3 / 15.8.5) → ✅ installs and launches fine 🔹 iOS Simulator (iOS 18.6 / 26) → ✅ works fine 🔹 iPad (iOS 18.7) → ❌ fails to install ➡️ Error message on iPad (iOS 18.7): 🔹 “Unable to install ‘’. Please try again later.” ➡️ What we’ve tried: 🔹 Cleaned and rebuilt the project (flutter clean, DerivedData removed) 🔹 Deployment Target is set to iOS 18.7 or lower. 🔹 Built the app using an Enterprise distribution profile, not a Development profile. 🔹 Works fine on older iPhones (iOS 15.8.3 / 15.8.5), so signing seems valid 🔹 Device has enough storage, and trust is granted under Settings › VPN & Device Management ➡️ Questions: 🔹 Could this be related to iOS 18.7’s signing or compatibility change? 🔹 Are there any known issues with enterprise installs on iOS 18.7? 🔹 Any insight from Apple engineers or others who faced this with iOS 18.7 would be extremely helpful. Thanks in advance!

I have a visionOS app using Apple's WebView and WebPage to display web content. When viewing a live YouTube stream last night, YouTube put up the warning in the area that would have the chat window: Oh no! It looks like you're using an older version of your browser. Please update it to use live chat. Anyone know if YouTube is generating this from the server based on the WebPage's user agent string, from Javascript running in the browser engine, or something else? Anyone know if and how it is possible to resolve this? (See right side of YouTube web page from a screen grab):

Anyone know how long it takes to get Apple to respond to a request for provisioning for endpoint security?

Since updating to iOS 26.0 (and confirmed on 26.1), ARBodyTrackingConfiguration no longer detects a valid ARBodyAnchor on devices with LiDAR (e.g., iPhone 15 Pro, iPhone 17 Pro Max). This issue reproduces in custom projects and Apple’s official sample “Capturing Body Motion in 3D”. The AR session runs normally, but the delegate call: func session(_ session: ARSession, didUpdate anchors: [ARAnchor]) never yields an ARBodyAnchor with valid joint transforms. All joints return nil when calling: body.skeleton.modelTransform(for: jointName) resulting in 0 valid joints per frame. Environment • Device: iPhone 17 Pro Max (LiDAR) • iOS: 26.0 / 26.1 • Xcode: 16.0 (stable) • Framework: ARKit + RealityKit • Configuration used: config.worldAlignment = .gravityAndHeading config.isAutoFocusEnabled = true config.environmentTexturing = .none session.run(config) Also tested: with and without frameSemantics = .bodyDetection Expected Behavior ARBodyAnchor should be detected and body.skeleton should contain ~89 valid joints with continuous updates.

Hi all, I work on a smart product that, for setup, uses a captive portal to allow users to connect and configure the device. It emits a WiFi network and runs a captive portal - an HTTP server operates at 10.0.0.1, and a DNS server responds to all requests with 10.0.0.1 to direct "any and all" request to the server. When iOS devices connect, they send a request to captive.apple.com/hotspot-detect.html; if it returns success, that means they're on the internet; if not, the typical behavior in the past has been to assume you're connected to a captive portal and display what's being served. I serve any requests to /hotspot-detect.html with my captive portal page (index.html). This has worked reliably on iOS18 for a long time (user selects my products WiFi network, iOS detects portal and opens it). But almost everyone who's now trying with iOS26 is having the "automatic pop up" behavior fail - usually it says "Error opening page - Hotspot login cannot open the page because the network connection was lost." However, if opening safari and navigating to any URL (or 10.0.0.1) the portal loads - it's just the iOS auto-detect and open that's not working iOS18 always succeeds; iOS26 always fails. Anybody have any idea what changes may have been introduced in iOS26 on this front, or anything I can do to help prompt or coax iOS26 into loading the portal? It typically starts reading, but then stops mid-read.

iPhone is throwing an error when starting Apple Tap to Pay transaction (other iPhones using the same merchant account working as expected) Error: Card reading failed due to unknown error: The operation couldn’t be completed. (ProximityReader.PaymentCardReaderSession.ReadError error 13.) We have tried full factory reset on the iPhone multiple times but still having the same issue. As mentioned issue is specific to one iPhone and other iPhones attached to the same merchant account have no issues taking Apple Tap to Pay transactions. Given the error is unknown / not documented, is it possible to get an explanation of what does error 13 means or what is causing it so we can troubleshoot accordingly?

開発アプリで通知確認を行うため、UDIDをプロビジョニングプロファイルに追加する必要があります。 iPhoneのUDIDは取得することができたのですが、AppleWatchのUDIDを取得する方法が分かりません。 Xcodeと接続してUDIDを取得しようとしましたが、iPhoneのみ認識がされAppleWatchが認識されていません。 AppleWatchもデベロッパモードをONしなければならないとAppleから返答をもらったが、その方法がわからないのでどなたかご教授お願い致します。

I've been experimenting with the Muse pen and understand that it can be accessed by my app through a SpatialTrackingSession, but is there any current or planned support for devices like this as for general UI input like game controllers are? For example, using the button as a tap analogue for SwiftUI views.

I understand that you want echoCancellation and noiseSuppression in most cases, but I would like to be able to turn off all the filter processes for this particular use case. When I set echoCancellation: false in navigator.mediaDevices.getUserMedia, Safari 26 on MacOS produces stereo recording even if I set channelCount: 1. When I set echoCancellation: true, it produces mono recording as expected. How can I get mono recording with echoCancellation: false and channelCount: 1? Thanks!

When I use BGContinuedProcessingTask to submit a task, my iPhone 12 immediately shows a notification banner displaying the task’s progress. However, on my iPhone 15 Pro Max, there’s no response — the progress UI only appears in the Dynamic Island after I background the app. Why is there a difference in behavior between these two devices? Is it possible to control the UI so that the progress indicator only appears when the app moves to the background?

We have developed Apple Wallet Extension for our App. The in-app provisioning for the card is working. However when we try to add the card from Wallet extension it gives error saying "Your issuer does not yet offer support for this card".

Context I’m deploying large language models on iPhone using llama.cpp. A new iPhone Air (12 GB RAM) reports a Metal MTLDevice.recommendedMaxWorkingSetSize of 8,192 MB, and my attempt to load Llama-2-13B Q4_K (~7.32 GB weights) fails during model initialization. Environment Device: iPhone Air (12 GB RAM) iOS: 26 Xcode: 26.0.1 Build: Metal backend enabled llama.cpp App runs on device (not Simulator) What I’m seeing MTLCreateSystemDefaultDevice().recommendedMaxWorkingSetSize == 8192 MiB Loading Llama-2-13B Q4_K (7.32 GB) fails to complete. Logs indicate memory pressure / allocation issues consistent with the 8 GB working-set guidance. Smaller models (e.g., 7B/8B with similar quantization) load and run (8B Q4_K provide around 9 tokens/second decoding speed). Questions Is 8,192 MB an expected recommendedMaxWorkingSetSize on a 12 GB iPhone? What values should I expect on other 2025 devices including iPhone 17 (8 GB RAM) and iPhone 17 Pro (12 GB RAM) Is it strictly enforced by Metal allocations (heaps/buffers), or advisory for best performance/eviction behavior? Can a process practically exceed this for long-lived buffers without immediate Jetsam risk? Any guidance for LLM scenarios near the limit?

I added a new device and it's not recognizing the device model. This causes a message saying "Unable to verify" when signing an app. Has anyone else encountered this issue? This only happens with this one device, not others.
