Reply to Xcode Signing Fails: Provisioning Profile "doesn't match" com.apple.developer.driverkit.userclient-access entitlement
Hi Kevin, Thank you for the suggestions. We have conducted a test of your third proposal regarding the IOKit User Client Class Temporary Exception. Our test procedure was as follows: We started from a known-good baseline commit where our DEXT loads correctly and the/dev/diskX node appears (though it reports 0 bytes, which is a separate issue we are debugging). We made only one change: we updated our App's .entitlements file to include the temporary exception. For absolute clarity, the exact content of the .entitlements file used for this test was: com.apple.security.temporary-exception.iokit-user-client-class IOUserUserClient com.apple.security.app-sandbox com.apple.developer.system-extension.install After a full clean, build, and reboot, the IOServiceGetMatchingService(DriverKitAcxxx) call still fails at runtime, returning IO_OBJECT_NULL. This result seems to indicate that the temporary exception entitlement is not sufficient to grant our app visibility of the active IOKit service on macOS. Be

Reoccurring World Tracking / Scene Exceeded Limit Error
Hi, We’ve been successfully using the RoomPlan API in our application for over two years. Recently, however, users have reported encountering persistent capture errors during their sessions. Specifically, the errors observed are: CaptureError.worldTrackingFailure CaptureError.exceedSceneSizeLimit What we have observed: Persistent Errors: The errors continue to occur even after initiating new capture sessions. Normal Usage: Our implementation adheres to typical usage patterns of the RoomPlan API without exceeding any documented room size limits. Limited Feature Usage: We are not utilizing the WorldTracking feature for the StructureBuilder functionality to stitch rooms together. Potential State Caching: Given that these errors persist across sessions, we suspect that there might be memory or state cached between sessions that is not being cleared, particularly since we are not taking advantage of StructureBuilder. Request: Could you please advise if there is any internal caching or memory retention bet

Reply to Best Practices for Binary Data (“Allows External Storage”) in Core Data with CloudKit Sync
When a Binary Data attribute is marked as “Allows External Storage”, large image files are stored as separate files on the device rather than inline in the SQLite store. That is correct. There is a threshold when the data will get stored in external files next to the SQLite database, similar to the approach that you described with URLs, but that process is managed by CoreData and transparent to your app you. How effective is this mechanism in keeping the Core Data store size small on the device? It depends on what you mean by the store. The SQLite file will be smaller, but the files are still stored on the device. Are there any recommended size thresholds or known limits for how many externally stored blobs can safely be managed this way? There is in general no limit. CoreData will decide when it's worth using an external file. If the blob you are storing is only a few bytes, it'll remain inline. If you expect to have a lot of assets, you should consider how you expect your app to behave when the use

Reply to Cannot Update Age Rating
I was able to change the age rating by making minor changes to my original app, checking “Yes” for the “Unrestricted Web Access“ question, uprating the age to 18 yrs and resubmitting. The app has no objectionable materials and aimed at adult and teen windsurfers and kite-boarders. This process seems a bit contrived, but it worked for me. Not sure it was necessary to actually change the code. Re-archiving and validating the original code may have been enough.

Apple not responding about upgrading to Organization account
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.

How can third-party iOS apps obtain real-time waveform / spectrogram data for Apple Music tracks (similar to djay & other DJ apps)?
Hi everyone, I’m working on an iOS MusicKit app that overlays a metronome on top of Apple Music playback. To line the clicks up perfectly I’d like access to low-level audio analysis data—ideally a waveform / spectrogram or beat grid—while the track is playing. I’ve noticed that several approved DJ apps (e.g. djay, Serato, rekordbox) can already: • Display detailed scrolling waveforms of Apple Music songs • Scratch, loop or time-stretch those tracks in real time That implies they receive decoded PCM frames or at least high-resolution analysis data from Apple Music under a special entitlement. My questions: 1. Does MusicKit (or any public framework) expose real-time audio buffers, FFT bins, or beat markers for streaming Apple Music content? 2. If not, is there an Apple program or entitlement that developers can apply for—similar to the “DJ with Apple Music” initiative—to gain that deeper access? 3. Where can I find official documentation or a point of contact for this kind of request? I’ve searched the

LockedCameraCapture Does Not Launch The App from Lock Screen
My implementation of LockedCameraCapture does not launch my app when tapped from locked screen. But when the same widget is in the Control Center, it launches the app successfully. Standard Xcode target template: Lock_Screen_Capture.swift @main struct Lock_Screen_Capture: LockedCameraCaptureExtension { var body: some LockedCameraCaptureExtensionScene { LockedCameraCaptureUIScene { session in Lock_Screen_CaptureViewFinder(session: session) } } } Lock_Screen_CaptureViewFinder.swift: import SwiftUI import UIKit import UniformTypeIdentifiers import LockedCameraCapture struct Lock_Screen_CaptureViewFinder: UIViewControllerRepresentable { let session: LockedCameraCaptureSession var sourceType: UIImagePickerController.SourceType = .camera init(session: LockedCameraCaptureSession) { self.session = session } func makeUIViewController(context: Self.Context) -> UIImagePickerController { let imagePicker = UIImagePickerController() imagePicker.sourceType = sourceType imagePicker.mediaTypes = [UTType.image.identifier, U

Performance degradation of HTTP/3 requests in iOS app under specific network conditions
Hello Apple Support Team, We are experiencing a performance issue with HTTP/3 in our iOS application during testing. Problem Description: Network requests using HTTP/3 are significantly slower than expected. This issue occurs on both Wi-Fi and 4G networks, with both IPv4 and IPv6. The same setup worked correctly in an earlier experiment. Key Observations: The slowdown disappears when the device uses: · A personal hotspot. · Network Link Conditioner (with no limitations applied). · Internet sharing from a MacBook via USB (where traffic was also inspected with Wireshark without issues). The problem is specific to HTTP/3 and does not occur with HTTP/2. The issue is reproducible on iOS 15, 18.7, and the latest iOS 26 beta. HTTP/3 is confirmed to be active (via assumeHttp3Capable and Alt-Svc header). Crucially, the same backend endpoint works with normal performance on Android devices and using curl with HTTP/3 support from the same network. I've checked the CFNetwork logs in the Console but haven't found

Can't Install WatchOS 26.1 beta 2
Beta two keeps hanging during the download process and says connect to wifi (which I am) or after hours it may download the beta 1.4gb file only to have to freeze in next processing step. I have tried all the resets, reinstalling both the watch and the phone running OS26.1 Beta 2 etc. The impact is the watch and the current software implementation is only getting a couple hours of battery usages before going dead

Reply to iPAD: achieve UserClient's privileges in background to have robust IOServiceAddMatchingNotification(...) as if ~[Background modes][Enable external communications].
Thanks a lot! ...adding external-accessory is not changing ANYTHING about how your app wakes/sleep in the background. You will not be allowed to use it, but that's because it's not relevant to your app. In my tests 2 weeks ago I (might be by my mistake) saw a correspondence between external-accessoryand the facts of callbacks from IOServiceAddMatchingNotification. Or at least correlation with the moments of such callbacks at the time of application moves from background to foreground. Having your unambiguous statement I tediously rechecked my environment now and I found 2 possible weak-points: A) I conducted the tests above having 2 identical DExts (for 2 different but very similar UserClient-Apps) formally enabled in Settings|Applications|Drivers. Though, of course, only one UserClient was active. I shall repeat the test (on near weeks) with single DExt physically installed. Another Q&A in TestFlight was being conducted in distant country. I shall reconfirm about the environment there. B)To distinguish t

Reply to Foundation Models inside of DeviceActivityReport?
Yeah, I see the following error when trying to prompt the on-device foundation model from within a device activity report extension (DeviceActivityReportExtension), which I believe is the same as what you mentioned: establishment of session failed with Unrecognized underlying error: Underlying connection was invalidated. Reason: failed at lookup with error 159 - Sandbox restriction ModelManagerError: got unrecognized error Underlying connection was invalidated. Reason: failed at lookup with error 159 - Sandbox restriction I am pretty sure that is as-designed. To give you more context, when responding your prompt, the model needs to communicate with the model manager, which is a system daemon that manages the inference requests. To protect the user’s privacy, however, the system doesn't allow a device activity report extension to move data outside the extension’s address space, and that prevents the model from creating a connection to the model manager. Having said that, if you have a compelling case
