A Summary of the WWDC25 Group Lab

Most folks who run into weird app group problems do so on the Mac, because app groups on the Mac are weird. See App Groups: macOS vs iOS: Working Towards Harmony. App groups on iOS are straightforward. There’s a single style (group.xyz) with a single entitlement (com.apple.security.application-groups) whose values must be authorised by a provisioning profile. It looks like you’re trying to use the com.apple.developer.app-groups entitlement. That’s just wrong, and your use of it explains the specific problem you’re hitting. I suspect you’ve been manually editing (or letting an LLM edit) you’re .entitlements file. If you use Xcode’s Signing & Capabilities editor to set this up in both your app and appex, it’ll do the right thing.

Thanks for the response. No, but iPadOS apps should not include com.apple.developer.driverkit.userclient-access. Note that your construction of that entitlement is also invalid (it's a list of bundle IDs and requires approval to use), We realized this was for MacOS only and since our app is for iOS, we plan to remove this. The actual bundleId was approved and we just use a censored bundle ID here Assuming the contents you've posted are accurate, then this mismatch is the problem: Those dictionaries must match in order for your DEXT to load. Yes, we also noticed the missing idVendor in our driver entitlement and updated it to match the provisioning profile. However, the issue still persists—our DriverKit is realized but does not start in the TestFlight build. Local Build (works): After enabling the driver and connecting the hardware, the system logs show the driver is both realized and started successfully. TestFlight Build (broken): On the same hardware and sequence, the system only logs the realization of th

(Continued) Can Vision Intelligence in Apple Intelligence be used to analyze a live camera feed and detect the dimensions of a box in real time? Is this possible using the new FoundationModels API, or would ARKit / RoomPlan be required? FoundationModels API is not multimodal and provides access to Apple’s on device large language model which is unrelated to machine learning models you’d use for bounding box detection. The Visual Intelligence framework does not support this use case as it is more focused on Visual Search and classification. How powerful is the apple intelligence on device model in terms of model size, architecture, and capabilities like reasoning, generalization, and zero-shot performance. It’s a large language model with 3 billion parameters, each quantized to 2 bits so good for summarization, extraction, classification, and many more use cases. It’s not designed for world knowledge or advanced reasoning. Knowing App Intents is the core element to integrate our apps with the system via Apple

filling the localization under subscription group solved it for me

The Unregistered (410) status is sent back on a best-effort basis, and on a fuzzy logic that may delay the status update randomly. Also, for a token to go into the Unregistered state, the device has to receive a push after the token is no longer valid on the device (either the app has been removed, or unregisterForRemoteNotifications() is called). One reason you are not seeing any (or as many) Unregistered status for background notifications could be that they are heavily throttled, and it could be that they are dropped before the point the status would be updated. In summary, Unregistered should be working for background notifications as well, but the reason you are not seeing could be due to how they are handled, and not necessarily due to an issue on your side.

[/quote] It’s hard to say without knowing more about the problem you’re experiencing. If this is a technical problem, then I recommend that you open a new thread here on the forums with the details [1]. Please pay careful attention to the topic, subtopic, and tags you choose, because many of us use that info to find relevant questions. For more info on how to use the forums effectively, see Quinn’s Top Ten DevForums Tips. OTOH, if this is a non-technical problem then the Apple Developer Forums might not be the right option. In that case, post a short summary of the issue here and I’ll see if I can offer a path forward.
