Overview

Hi, I'm not sure whether this is the appropriate forum for this topic. I just followed a link from the JAX Metal plugin page https://developer.apple.com/metal/jax/ I'm writing a Python app with JAX, and recent JAX versions fail on Metal. E.g. v0.8.2 I have to downgrade JAX pretty hard to make it work: pip install jax==0.4.35 jaxlib==0.4.35 jax-metal==0.1.1 Can we get an updated release of jax-metal that would fix this issue? Here is the error I get with JAX v0.8.2: WARNING:2025-12-26 09:55:28,117:jax._src.xla_bridge:881: Platform 'METAL' is experimental and not all JAX functionality may be correctly supported!

I get a lot of downloads from outside USA but almost no conversion (subscription/IAP) from those countries. Apple App Store does the price conversion based on currency conversion and VAT but it does not take into account that $10 in India or Argentina is a much bigger portion of ones income compared to a US person. Converting all these prices (175 of them) manually is very cumbersome for each subscription tier and for each region.

Has anyone noticed that there are way too many bugs caused by the liquid glass issues? I'm noticing apple adding private layer classes between existing UI views to add glassy effect and no way to disable them. Some of these bugs have no way around without rewriting the code from. For example, search controller doesn't work anymore on iOS 26 but does work on iOS 18. The tab bar controller doesn't show at all on iOS 26 but does on iOS 18. I'm wondering if other people are facing the same issues.

Greetings, and Happy Holidays, I've been building an on-device AI safety layer called Newton Engine, designed to validate prompts before they reach FoundationModels (or any LLM). Wanted to share v1.3 and get feedback from the community. The Problem Current AI safety is post-training — baked into the model, probabilistic, not auditable. When Apple Intelligence ships with FoundationModels, developers will need a way to catch unsafe prompts before inference, with deterministic results they can log and explain. What Newton Does Newton validates every prompt pre-inference and returns: Phase (0/1/7/8/9) Shape classification Confidence score Full audit trace If validation fails, generation is blocked. If it passes (Phase 9), the prompt proceeds to the model. v1.3 Detection Categories (14 total) Jailbreak / prompt injection Corrosive self-negation ("I hate myself") Hedged corrosive ("Not saying I'm worthless, but...") Emotional dependency ("You're the only one who understands") Third-person manipulation ("If you refuse, you're proving nobody cares") Logical contradictions ("Prove truth doesn't exist") Self-referential paradox ("Prove that proof is impossible") Semantic inversion ("Explain how truth can be false") Definitional impossibility ("Square circle") Delegated agency ("Decide for me") Hallucination-risk prompts ("Cite the 2025 CDC report") Unbounded recursion ("Repeat forever") Conditional unbounded ("Until you can't") Nonsense / low semantic density Test Results 94.3% catch rate on 35 adversarial test cases (33/35 passed). Architecture User Input ↓ [ Newton ] → Validates prompt, assigns Phase ↓ Phase 9? → [ FoundationModels ] → Response Phase 1/7/8? → Blocked with explanation Key Properties Deterministic (same input → same output) Fully auditable (ValidationTrace on every prompt) On-device (no network required) Native Swift / SwiftUI String Catalog localization (EN/ES/FR) FoundationModels-ready (#if canImport) Code Sample — Validation let governor = NewtonGovernor() let result = governor.validate(prompt: userInput) if result.permitted { // Proceed to FoundationModels let session = LanguageModelSession() let response = try await session.respond(to: userInput) } else { // Handle block print("Blocked: Phase \(result.phase.rawValue) — \(result.reasoning)") print(result.trace.summary) // Full audit trace } Questions for the Community Anyone else building pre-inference validation for FoundationModels? Thoughts on the Phase system (0/1/7/8/9) vs. simple pass/fail? Interest in Shape Theory classification for prompt complexity? Best practices for integrating with LanguageModelSession? Links GitHub: https://github.com/jaredlewiswechs/ada-newton Technical overview: parcri.net Happy to share more implementation details. Looking for feedback, collaborators, and anyone else thinking about deterministic AI safety on-device. parcri.net has the link :)

I’m concerned because my iCloud account was recently migrated to AWS (Amazon Web Service) against my will, and now it seems.like people are rummaging through my files, photos, and mail, When I try to contact Apple Support, I get bumped to a spoofed site. Calling the hotline is the same, I get a Siri operator with platitudes and gaslighting but no action. I have run sysdiagnose and it looks really sketchy. Can anyone help?

My #1 crash report since iOS 26 is the following: 1 libobjc.A.dylib objc_exception_throw 2 Foundation -[NSAssertionHandler handleFailureInMethod:object:file:lineNumber:description:] 3 UIKitCore -[UINavigationBar layoutSubviews] 4 UIKitCore UIView._layoutSubviewsWithObservationTracking() 5 UIKitCore @objc UIView._layoutSubviewsWithObservationTracking() Thread 0 9 libobjc.A.dylib objc_exception_throw 10 Foundation -[NSAssertionHandler handleFailureInMethod:object:file:lineNumber:description:] 11 UIKitCore -[UINavigationBar layoutSubviews] 12 UIKitCore UIView._layoutSubviewsWithObservationTracking() 13 UIKitCore @objc UIView._layoutSubviewsWithObservationTracking() I tried many things, without success so far. It seemed related to the new view update with observation tracking: link to documentation Any lead on how I should investigate this? Many thanks in advance!!

Hello everybody. I need your help with configuring navigationItem properly. I want to use its appearance properties to configure how the navigation bar looks on per-screen basis without interacting with UINavigationBar directly (the API has been implemented for this specific use case, right?) What I'm confused about is that setting any appearance property resets back button image to the default chevron. What I do now: Inside my app delegate let navigationBarAppearance = UINavigationBar.appearance() navigationBarAppearance.backIndicatorImage = UIImage() navigationBarAppearance.backIndicatorTransitionMaskImage = UIImage() I do this to hide the default chevron to customize back button appearance on per-view-controller basis Then in my presenting view controller: override func viewDidLoad() { super.viewDidLoad() navigationItem.title = "Root" navigationItem.backBarButtonItem = UIBarButtonItem( title: nil, image: nil, primaryAction: UIAction( title: "", image: UIImage(systemName: "square.and.arrow.up"), identifier: nil, discoverabilityTitle: nil, attributes: [], state: .on, handler: { [weak self] _ in self?.navigationController?.popViewController(animated: true) } ), menu: nil ) let appearance = UINavigationBarAppearance() appearance.configureWithTransparentBackground() appearance.backgroundColor = UIColor.red appearance.titleTextAttributes = [ .foregroundColor: UIColor.purple ] appearance.largeTitleTextAttributes = [ .foregroundColor: UIColor.purple ] navigationItem.standardAppearance = appearance navigationItem.compactAppearance = appearance navigationItem.scrollEdgeAppearance = appearance navigationItem.compactScrollEdgeAppearance = appearance } The colors are set up as expected, however the default chevron image appears on the next view controller next to square.and.arrow.up. If I don't touch navigation item appearance properties - only square.and.arrow.up is displayed, as I want, but obviously I loose all the customization. Can anyone please explain how to set things up properly? Thanks!

Since watchOS 26, watch face sharing has stopped working completely. I tested the following: Sharing via CLKWatchFaceLibrary Other public APIs Sharing via iMessage In all cases, the watch face cannot be reinstalled after being shared. This issue is not limited to my app. Large third-party apps such as Facer and other major watch face platforms are also affected, which suggests this is a system-level change or bug. Everything worked correctly before watchOS 26. Has Apple officially acknowledged this issue? Is there a recommended place to report or track this bug?

Hi, I have created an AppIntent in which there is a parameter called price, I have set the default value as 0. @Parameter(title: "Price", default: 0) var price: Int Problem When the shortcut is run this parameter is skipped Aim I still want to price to be asked however it needs to be pre-filled with 0 Question What should I do that the shortcut can still ask the price but be pre-filled with 0?

Hi everyone, I enrolled in the Apple Developer Program on the evening of December 22, 2025, and the membership fee has already been successfully charged to my bank account. It's 8 days without program... However, my account is still showing a “Pending” status with the message “Subscribe your membership.”

Overview I have a custom type Statistics that has 3 properties inside it I am trying to return this as part of the AppIntent's perforrm method struct Statistics { var countA: Int var countB: Int var countC: Int } I would like to implement the AppIntent to return Statistics as follows: func perform() async throws -> some IntentResult & ReturnsValue<Statistics> { ... ... } Problem It doesn't make much sense to make Statistics as an AppEntity as this is only computed as a result. Statistics doesn't exist as a persisted entity in the app. Questions How can I implement Statistics? Does it have to be AppEntity (I am trying to avoid this)? (defaultQuery would never be used.) What is the correct way tackle this?

I’m seeing consistent failures using SoundAnalysis live classification when my app moves to the background. Setup iOS 17.x AVAudioEngine mic capture SNAudioStreamAnalyzer SNClassifySoundRequest(classifierIdentifier: .version1) UIBackgroundModes = audio AVAudioSession .record / .playAndRecord, active Audio capture + level metering continue working in background (mic indicator stays on) Issue As soon as the app enters background / screen locks: SoundAnalysis starts failing every second with domain:com.apple.SoundAnalysis, code:2(SNErrorCode.operationFailed) Audio capture itself continues normally When the app returns to foreground, classification immediately resumes without restarting the engine/analyzer Question Is live background sound classification with the built-in SoundAnalysis classifier officially unsupported or known to fail in background? If so, is a custom Core ML model the only supported approach for background detection? Or is there a required configuration I’m missing to keep SNClassifySoundRequest(.version1) running in background? Thanks for any clarification.

I want that the user can watch a short clip in the App Store before the user decides to download my game in the App Store. I want to upload a clip to App Store Connect but I don't know how to do that. And I get this warning: To provide metadata for your app clip, you must first upload a build to App Store Connect that contains a clip. Is it necessary that the user can watch the clip in my game or should the video file just be included in the build even if the clip cannot be watched in my game? Is it necessary to upload the clip first to YouTube and then paste the URL in App Store Connect?

In App Store Connect I can add up to 10 images for each iPhone/iPad display. But I don't know which resolution is the best for my screenshots in the App Store and I don't know if the screenshots could be displayed distorted if I don't upload png images for each iPhone/iPad display in App Store Connect. Should I upload for each iPhone/iPad display up to 10 screenshots in the highest possible resolution? For example, for the iPhone 6.5" display it would be 1284 × 2778px or 2778 × 1284px.

I coded two demo websites as follows (both written in NextJS): Website 1: I coded an interval counter that increments every 1 second. Website 2: I used the MediaRecorder API (described in the WebKit documentation: https://webkit.org/blog/11353/mediarecorder-api/). In the ondataavailable function, I periodically send a blob (once every 1 second) to my server. In the backend, I coded a POST API to upload this blob. I noticed that with website 1, the interval doesn't work when I run Safari in the background, even on iOS and iPadOS. However, website 2 works, meaning it still calls my API normally (I tried running Safari in the background for about 1-2 hours and it worked). So, does this mean Apple allows native APIs like MediaRecorder and its callbacks to run in the background?

Hello, the Liquid Glass effect of iOS 26 was possible during development, but it disappeared after its release and launch. I haven't found the reason for this, could you please help me clarify

The situation is as follows: Recently, we upgraded from an individual developer account to a company account about 2–3 weeks ago. When it came time to renew the account, it was strange that the fee displayed was $99 instead of $299. We had no way to change this, so we proceeded with the $99 payment. After that, Apple introduced new terms and conditions. When we tried to accept them, the account status did not change at all. I clicked “Accept” many times, but it remained in pending status. When I checked the browser console (F12), I noticed that Apple was returning a 500 error, but this error was not shown anywhere in the UI. I have called and emailed Apple support many times. However, they insist that our company account is already active and that we just need to accept the terms and conditions. Unfortunately, we are unable to accept them due to the error returned by Apple’s system. I explained this to them, but they still insist that we simply follow their instructions. As a result, we are currently stuck and do not know how to proceed so that the account can be fully activated and our app can return to the Apple App Store: We accepted Apple's terms on the 22nd. Organization account with $99, unclear why: I've clicked accept many times but it didn't work (Apple error 500), and the status remains pending: Therefore, I am hoping to get help from this forum in case anyone has experienced a similar issue and found a solution.

Hi everyone - I really hope you can help. I recently tried to apply to the Developer Program. I did this by starting the process online in a browser, then following the Apple instructions to open the Developer App on my phone, identify myself and then go through the process of filling in the details for the type of application (Individual) and the type of apps I'm interested in creating then paying a subscription (all on the phone). I can see the subscription exists in my iCloud account now. I also have not only the initial "Your subscription is confirmed" email I also have the later "Your invoice from Apple" too. However if I go to the developer website it says at the top of the page "To continue your enrolment, complete your purchase now. Your purchase may take 48 hours to process". Did anyone else have this issue? Is it all ok and I just have to wait and wait for the application to be approved? Is there something I need to do? I'm worried that if I follow the instructions in my Developer account online I will pay twice. I really need to get this sorted asap. When I try to use the full developer profile in xCode in "signing" I get "Cannot create a iOS App Development provisioning profile for "com.********.[appname]". Personal development teams, including "[my personal developer account name]", do not support the iCloud capability. Thanks so much in advance for help from anyone in the forum!

Hey I'm using the CIDepthBlurEffect Core Image Filter in my app. It seems to work ok but I get these errors in the console when calling the class. CoreImage Metal library does not contain function for name: sparserendering_xhlrb_scan CoreImage Metal library does not contain function for name: sparserendering_xhlrb_diffuse CoreImage Metal library does not contain function for name: sparserendering_xhlrb_copy_back CoreImage Metal library does not contain function for name: plain_or_sRGB_copy Am I missing some sort of import to gain these Metal functions? I am using my own custom shaders but I assume you'd be able to use them along side the built in ones.

When changing the app icon: On iOS versions below 26.1, we were able to use certain methods to suppress this confirmation popup ("You have changed the icon for 'Lanhai Bank'"). However, this suppression no longer works on iOS 26.1 and later. Is there any valid method to prevent this popup from appearing on iOS 26.1+? Any insights would be greatly appreciated! /用户/lanhaiyinhang/下载/微信bdf77ae6f15408892b6734696d6c2038.jpg
