Hi everyone, 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

Hi, I'm using LanguageModelSession and giving it two different tools to query data from a local database. I'm wondering how I can have the session generate structured content as the response that includes data one or both tools (or no tool at all). Here is an example of what I'm trying to do: Let's say the app has access to a database that contains information about exercise and sleep data (this is just an analogy). There are two tools, GetExerciseData() and GetSleepData(). The user may then prompt something like, how well did I sleep in November. I have this working so that it calls through to the right tool, which would return a SleepSummary. However, I can't figure out how to have the session return the right structured data. I can do this and get back good text data: let response = session.respond(to: userInput), but I believe I want to do something like: let response = session.respond(to: trimmed, generating: ) Sometimes the model I run one tool or the other, or both tools, or no tool a

Hi everyone, I am seeking urgent advice or attention from the App Review team regarding a Pending Termination Notice I received for Section 3.2(f). The Situation: I recently acquired a portfolio of apps from another developer to start my business on the App Store. Three months after the transfer, my account was flagged for removal because one of these acquired apps repeatedly violated guidelines to evade the review process. The Problem: I am being punished for the previous owner's actions. I have never submitted a new build, metadata update, or review request for this specific app since acquiring it. The Timeline (Proof of Innocence): August 4, 2025: Last update submitted by the Previous Owner. September 6, 2025: I signed the Purchase Agreement to start my business. September 9, 2025: App Transferred to my account. December 11, 2025: Termination Notice received. As the timeline proves, the alleged evasion attempts via submissions occurred before I even owned the app. Regarding Unresolved Issues: I am aware th

I am trying to notarize a VS-Code Fork Electron based app for non-App store distribution. Its just same for more than 24hrs, it just says processing. Looking for someone who could help me. Thanks

I built this very simple example to demonstrate the issue im facing on iOS 26 when trying to use custom ToolbarItem element for .largeTitle. Code: struct ContentView: View { var body: some View { NavigationStack { Screen() .navigationTitle(First) .toolbar { ToolbarItem(placement: .largeTitle) { Text(First) .font(.largeTitle) .border(Color.black) } } .navigationDestination(for: Int.self) { integer in DestinationScreen(integer: integer) } } } } struct Screen: View { var body: some View { List { ForEach(1..<50) { index in NavigationLink(value: index) { Text(index.description) .font(.largeTitle) } } } } } struct DestinationScreen: View { let integer: Int var body: some View { HStack { Text(integer.description) .font(.largeTitle) Spacer() } .padding() .navigationTitle(integer.description) .toolbar { ToolbarItem(placement: .largeTitle) { Text(integer.description) .font(.largeTitle) .border(Color.black) } } } } As shown on the gif, when navigating between pages, titles are going to overlap for a short wh

Hi, I am using xCode26.x. But my Metal4 classes are not compiling. I downloaded the sample code from Apple's website - https://developer.apple.com/documentation/Metal/processing-a-texture-in-a-compute-function. For example, I am getting errors like Cannot find protocol declaration for 'MTL4CommandQueue'; I have hit a deadline. Any recommendations are very welcome. I have downloaded the Metal Tool chain. When I run the following commands on the terminal - xcodebuild -showComponent metalToolchain ; xcrun -f metal ; xcrun metal --version I get the following response - Asset Path: /System/Library/AssetsV2/com_apple_MobileAsset_MetalToolchain/86fbaf7b114a899754307896c0bfd52ffbf4fded.asset/AssetData Build Version: 17A321 Status: installed Toolchain Identifier: com.apple.dt.toolchain.Metal.32023 Toolchain Search Path: /Users/private/Library/Developer/DVTDownloads/MetalToolchain/mounts/86fbaf7b114a899754307896c0bfd52ffbf4fded /Users/private/Library/Developer/DVTDownloads/MetalToolchain/mounts/86fbaf7b114a899

SwiftUI's colorScheme modifier is said to be deprecated in favour of preferredColorScheme but the two work differently. See the below sample app, colorScheme changes the underlying view colour while preferredColorScheme doesn't. Is that a bug of preferredColorScheme? import SwiftUI struct ContentView: View { let color = Color(light: .red, dark: .green) var body: some View { VStack { HStack { color.colorScheme(.light) color.colorScheme(.dark) } HStack { color.preferredColorScheme(.light) color.preferredColorScheme(.dark) } } } } #Preview { ContentView() } @main struct TheApp: App { var body: some Scene { WindowGroup { ContentView() } } } extension UIColor { convenience init(light: UIColor, dark: UIColor) { self.init { v in switch v.userInterfaceStyle { case .light: light case .dark: dark case .unspecified: fatalError() @unknown default: fatalError() } } } } extension Color { init(light: Color, dark: Color) { self.init(UIColor(light: UIColor(light), dark: UIColor(dark))) } }

When a user enables an SMS filtering extension via iOS Settings → Messages → Text Message Filtering and selects an app, the following prompt appears: The developer of [App Name] will receive the text, attachments and sender information in text messages from senders not in your Contacts. Messages may include personal or sensitive information like bank verification codes. This message cannot be modified by developers, and we're receiving complaints and negative reviews from users who are alarmed by it, despite our app not collecting any data. iOS should allow developers to customize this message or reword this message to not make false claims about data collection. We've opened a feedback assistant report here: FB21445903

Hello, We are experiencing on some occasions a wrong behavior with PDFDocument method: func page(at index: Int) -> PDFPage? With certain PDF files, this method returns the wrong PDFPage. This occurs on iOS 18.3, 18.5 and 18.6.2 (an maybe on other versions). Try this PDF for instance (page 81 is returned when index = 2): https://drive.google.com/open?id=1MHm2wjfsbWB8OiRmARUMmvODYxp4DIqP&usp=drive_fs Also, I mention that this doesn't occur systematically with this PDF. When making a copy of this file we don't observe the issue. Could this be linked some kind of internal cache issue ?

Since upgrading to Mac OS 10.5 Beta-2, daemons launched with launchctl are failing to open Desktop/Documents/Downloads files and folders even in read mode with an error Operation not permitted.Does anyone facing this issue?

Hi! We have created an app that communicates with devices over BLE, and it is currently out in Testflight. It works as expected for almost everyone, but for some users we get a strange behaviour. We start by scanning for devices with scanForPeripherals(withServices:options:), then connect, and finally initiate pairing by subscribing and writing to a pair of characteristics, which both require encryption. The issue is that for these users, the following code: func peripheral( _ peripheral: CBPeripheral, didDiscoverCharacteristicsFor service: CBService, error: Error? ) { guard error == nil else { LogManager.shared.log( ❌ Error discovering characteristics: (error!) ) return } for characteristic in service.characteristics ?? [] { if characteristic.uuid == controlPointUUID { controlPointCharacteristic = characteristic LogManager.shared.debugLog( Control Point characteristic found. ) } else if characteristic.uuid == statusUUID { statusCharacteristic = characteristic LogManager.shared.debugLog(Notify charac
