Reply to The APP was not awakened after start a liveactivity
Thank you for your post. There are a few details that need clarification. Could you please provide the iOS version you are using? Additionally, how do you ascertain that the app is not receiving the token? A more detailed description of how to initiate the activity or if the user initiates the activity would be greatly appreciated. Do you have logs on these method to see if gets called? On the TASK I would add some logs to see when it gets called. https://developer.apple.com/documentation/activitykit/starting-and-updating-live-activities-with-activitykit-push-notifications Additionally, it is crucial to trace the issue if possible. Kindly provide me with the following information for a failed notification: The precise time and date (including the time zone) of the push notification. The public IPv4 address of the server that sent the push notification. The push topic (apns-topic header value). The app’s Bundle ID. The device token. The apns-id if it is set. The full contents of the headers and the payload. An

Reply to Building macOS apps with Xcode 26 on macOS 26 VM
@RickMaddy I think that might be a little out of scope for this thread. But in any case, I was able to update my macOS 26.1b2 VM to 26.1b3 via my logged-in Apple Account, so I don't think it's universally broken. Although my host is still on Sequoia 15.7.1. The closest thing I've experienced to what you're describing is an issue that I've seen for a while where logging in with an Apple Account hasn't been working for me if I have physical security keys enabled on my account for 2FA (FB19614234). Unfortunately if you're in this situation I don't know of any workaround other than removing all the security keys (and even if you re-enable them after logging in with the VM, eventually the VM will start complaining with pop-ups asking you to login again, although beta updates will still work despite this). This isn't new to 26.1, though. If this isn't the issue you're experiencing you might find better luck creating a new thread since I don't think many people with similar issues are going to find

Building macOS apps with Xcode 26 on macOS 26 VM
I'm trying to setup a macOS 26 build environment in a VM (using UTM and the virtualization framework Apple provides). I have Xcode 26 installed and have logged into my Apple ID and verified that the team and other configuration looks fine in Xcode settings. When trying to build the macOS app, I see errors saying the VM's device ID has not been registered. I have confirmed that the device ID is registered both in the Provisioning portal AND the downloaded .provisionprofiles (in Library > Developer > Xcode > UserData). This problem appears on multiple targets (e.g. the main app and extensions). If I try to manually provision the app, using the Provisioning portal, I can build the product, but it will not launch because of Gatekeeper issues. Finally, signing to run locally doesn't work either. As the app launches, frameworks refuse to load because Team IDs don't match. With ad hoc provisioning, there are no Team IDs. I've come to the conclusion that this just isn't possible. Which is a

URL Filtering: Bloom Filter authoring
Hello, As I've been tinkering with the new URL filtering API I've been struggling to create bloom filters. I have been referencing this developer's post heavily: https://developer.apple.com/forums/thread/791352?answerId=851527022#851527022 He suggests that the expected FNV-1a implementation has the multiply and xor operations inverted, while an Apple engineer suggests that this will be updated on the offical iOS26 release (which has already happened). What is the correct FNV-1a implementation? In this sample project (which is from july, so pre-release ios 26): https://developer.apple.com/documentation/networkextension/filtering-traffic-by-url Is the included bloom filter data correct? I can only assume the other developer used this as a reference to then conclude that multiplying and xor-ing should be inverted, so I'm really not sure if this bloom filter bitVectorData here is trustworthy. Is there any reference implementation for this hashing procedure? How do we generate a bloom filter properly and

Matter Media Playback Cluster
Hello, I am currently working on personal project based on Matter. I need to create a Basic Video Player as specified in Matter's standard embedding the Media Playback Cluster. I went through the reading of how Apple now supports Matter as a standard : linkText My understanding of the following schematic, is alongside : HomeKit Accessory Protocol (HAP) Framework API Related HAP accessories underneath the homeKit framework. Developpers also find under the Homekit framework : CHIP (Connected Home IP) Framework API Related Matter accessories this time Both types of accessories/devices can be commissioned in the HomeKit ecosystem seemlessly. Each framework has it's documentation : HAP : https://developer.apple.com/documentation/homekit/hmhomemanager CHIP : https://developer.apple.com/documentation/matter I want through the process of installing XCode and the HomeKit Accessory Simulator. In the list of HomeKit Accessories I did not see any Media related devices : The list of currently supported devices is

Reply to Matter Media Playback Cluster
Kevin and ssmith_c for your assistance. I fortunately managed to file in the bug: FB20677188 Thank you! Looking over the bug, there was one point I wanted to comment on: For the Matter Media Device Basic Video Player Type Apple Home does support the commissioning (adding the device to the list of accessories displayed in Home App), but no controls are displayed. Not even the mandatory required controls: ... This type of Matter Device, which is part of the standard, should at least expose the mandatory controls and commands. The idea that Apple (and general ecosystem vendors more broadly) should try and support the full range of the Matter specification is, IMHO, one of those ideas which sounds reasonable on the surface but is, in fact, a very bad idea. First off, quoting myself: The Matter specification itself is sufficiently broad and complex that, in practice, I'm not sure it will ever really be possible to create a high-quality controller app* that actually supports EVERY possible accesso

ARSkeleton3D modelTransform always return nil
I use ARKit for motion tracking. I get the skeleton joint coordinates and use them for animation. I didn't make any changes to the code, but I updated the iOS version from 18 to 26, and modelTransform now always returns nil. https://developer.apple.com/documentation/arkit/arskeleton3d/modeltransform(for:) For example bodyAnchor.skeleton.modelTransform(for: .init(rawValue: head_joint)) bodyAnchor is ARBodyAnchor. I see the default skeleton on the screen, but now I can't get the coordinates out of it. I'm using an example from Apple's WWDC presentation. https://developer.apple.com/documentation/arkit/capturing-body-motion-in-3d Are there any changes in the API? Or just bug?

Request File Access from Unity for Apple Vision Pro
Hi, I am trying to load files from the Apple Vision Pro's storage into a Unity App (using Apple visionOS XR Plugin and not PolySpatial package). So far, I've tried using UnitySimpleFileBrowser and UnityStandaloneFileBrowser (both aren't made for the Vision Pro and don't work there), and then implemented my own naive file browser that at least allows me to view directories (that I can see from the App Sandbox). This is of course very limited: Gray folders can't be accessed, the only 3 available ones don't contain anything where a user would put files through the Files app. I know that an app can request access to these Files & Folders: So my question is: Is there a way to request this access for a Unity-built app at the moment? If yes, what do I need to do? I've looked into the generated Xcode project's Capabilities, but did not find anything related to file access. Any help is appreciated!

Reply to Request File Access from Unity for Apple Vision Pro
I am working on a Gaussian Splatting App using the UnityGaussianSplatting package and building for Apple Vision Pro. I want to be able to load splat (.ply / .splat) files from the Vision Pro's storage into the application. OK. So the main issue to be aware of here is the difference between works fine for a developer and works well for a user. For development purposes, you can basically just set the two keys (UIFileSharingEnabled/LSSupportsOpeningDocumentsInPlace) and then use your Documents directory as your working storage. There could be issues if you edited or deleted those files while your app was actively running, but you will just avoid those issues... by not doing that. On the other hand, if you're planning to ship this to end users then you'll need to use things like file coordination to avoid those issues. Similarly, apps that are more viewer oriented (meaning, they don't edit the files they're working with) often use an import model where they copy (actually clone, so they don't use additio

Recorded video looks blurry, color-washed, low bitrate, compressed using ScreenCaptureKit
Hello everyone, I am trying to implement ScreenCaptureKit into my project, I am using MacOs 26 for the target version and followed this official project from apple regarding the screencapture kit. https://developer.apple.com/documentation/ScreenCaptureKit/capturing-screen-content-in-macos I used the official exact code and implemented in my app, but the results are not good. The video look blurry, unclear, lost colors and its like 720p honestly. The 1st video frame t is result when I integrate it in my app. After that, I used another app ( which was built in electron, they were using screencapturekit as well ) and there results were a lot better. The 2nd video frame is when I recorded using their application. It appears as close to as system display I tried multiple things, but no impressive results. For my purpose, I want to the final recorded video to be as good as the display quality of the system. I also applied .hdr local display and coronolicial, but no help with that as well.

Reply to Clarification on APNs MDM Push Certificate per-customer requirement for MSP/multi-tenant MDM
I can't give legal advice on whether potential actions violate the terms of developer agreements. I suggest that having your customers manage their own MDM push certificates makes sense from the point of view of segmentation of risk. MDM is a very powerful technology, and rarely people abuse it. When Apple becomes aware of abuse of MDM it may take various actions in response. These actions may include revoking the MDM push certificate involved in the abuse, revoking the MDM vendor certificate associated with the MDM push certificate, removing the MDM CSR permission, and/or terminating any Apple Accounts, Apple Developer Program accounts, or Apple Developer Enterprise accounts associated with those certificates. As a device management service vendor, consider if one of your customers abuses device management capabilities and Apple revokes the MDM push certificate and the associated Apple Account. If your device management service used the same MDM push cert

Clarification on APNs MDM Push Certificate per-customer requirement for MSP/multi-tenant MDM
Hello Apple Developer Community, We’re building an MDM product (SaaS, multi-tenant). I’d like clarification on the APNs MDM push certificate usage model for service providers (MSPs). Question: Is it acceptable for an MDM vendor to use a single APNs MDM push certificate owned by the vendor to manage devices for multiple, independent customer organizations? Or is it required/recommended that each customer (company) must obtain and use its own APNs MDM push certificate (issued under the customer’s Apple ID) for their tenant? Why we’re asking: We understand that many guides show the process where each customer logs into the Apple Push Certificates Portal with their own Apple ID, uploads a CSR provided by the MDM, and then renews yearly. Practically, for a small team and early-stage deployments, using one vendor-owned certificate across multiple tenants would be simpler. We want to ensure we’re not violating any policy, terms, or technical requirements (e.g., certificate ownersh
