Overview

Hello, I'm trying to make a DEXT for a thunderbolt device. I started from the DriverKit template that does a very simple Hello World. I added the DriverKit PCI (development) entitlement in the developer portal. The dext is installed and activated but when I connect my thunderbolt device this is what I see in the console log: kernel DK: mydrv-0x100010a85 waiting for server com.mycompany.mydrvApp.mydrv-100010a85 kernel Driver com.mycompany.mydrvApp.mydrv has crashed 0 time(s) kernelmanagerd Launching dext com.mycompany.mydrvApp.mydrv com.mycompany.mydrvApp.mydrv 0x100010a81 e675cb5ca6b6650163cc231c6af2f7e730b56b0bf394b857ce76f8e3105eb0f1 kernel DK: mydrv-0x100010a89 waiting for server com.mycompany.mydrvApp.mydrv-100010a89 kernelmanagerd Launching driver extension: Dext com.mycompany.mydrvApp.mydrv v1 in executable dext bundle com.mycompany.mydrvApp.mydrv at /Library/SystemExtensions/DC2F3964-043D-445E-A6CF-A9D7C529B39A/com.mycompany.mydrvApp.mydrv.dext default 16:52:31.551867-0500 kernel /Library/SystemExtensions/DC2F3964-043D-445E-A6CF-A9D7C529B39A/com.mycompany.mydrvApp.mydrv.dext/com.mycompany.mydrvApp.mydrv[15788] ==> com.apple.dext kernelmanagerd Found 1 dexts with bundle identifier com.mycompany.mydrvApp.mydrv kernelmanagerd Using unique id e675cb5ca6b6650163cc231c6af2f7e730b56b0bf394b857ce76f8e3105eb0f1 to pick dext matching bundle identifier com.mycompany.mydrvApp.mydrv kernelmanagerd Picked matching dext for bundle identifier com.mycompany.mydrvApp.mydrv: Dext com.mycompany.mydrvApp.mydrv v1 in executable dext bundle com.mycompany.mydrvApp.mydrv at /Library/SystemExtensions/DC2F3964-043D-445E-A6CF-A9D7C529B39A/com.mycompany.mydrvApp.mydrv.dext kernelmanagerd Launching dext com.mycompany.mydrvApp.mydrv com.mycompany.mydrvApp.mydrv 0x100010a85 e675cb5ca6b6650163cc231c6af2f7e730b56b0bf394b857ce76f8e3105eb0f1 kernel DK: com.mycompany.mydrvApp.mydrv[15788] has team identifier L86BQ63GK2 kernelmanagerd Launching driver extension: Dext com.mycompany.mydrvApp.mydrv v1 in executable dext bundle com.mycompany.mydrvApp.mydrv at /Library/SystemExtensions/DC2F3964-043D-445E-A6CF-A9D7C529B39A/com.mycompany.mydrvApp.mydrv.dext kernel kernel DK: mydrv-0x100010a81: provider entitlements check failed kernel DK: IOUserServer(com.mycompany.mydrvApp.mydrv-0x100010a81)-0x100010a8a::exit(Entitlements check failed) What am I missing for the check to pass?

Hi, My app uses the NetworkExtension framework to connect to an access point. For some reason, my app occasionally fails to find and/or connect to my AP (which I know is online and beaconing on a given frequency). This roughly happens 1/10 times. I am using an iPhone 17, running iOS 26.0.1. I am connecting to a WPA2-Personal network. In the iPhone system logs, I see the following: Oct 10 10:34:10 wifid(WiFiPolicy)[54] <Notice>: Dequeuing command type: "Scan" pending commands: 0 Oct 10 10:34:10 wifid(WiFiPolicy)[54] <Notice>: __WiFiDeviceCopyPreparedScanResults: network records count: 0 Oct 10 10:34:10 kernel()[0] <Notice>: wlan0:com.apple.p2p: WiFi infra associated, NAN DISABLED, , DFS state Off, IR INACTIVE, llwLink ACTIVE, RTM-DP 0, allowing scans Oct 10 10:34:10 kernel()[0] <Notice>: wlan0:com.apple.p2p: isScanDisallowedByAwdl[1148] : InfraScanAllowed 1 (RTModeScan 0 NonSteering 0 assistDisc 0 HTMode 0 RTModeNeeded 0 Immin 0 ScanType 1 Flags 0 ScanOn2GOnly 0 DevAllows2G 1) Oct 10 10:34:10 kernel()[0] <Notice>: wlan0:com.apple.p2p: IO80211PeerManager::setScanningState:5756:_scanningState:0x2(oldState 0) on:1, source:ScanManagerFamily, err:0 Oct 10 10:34:10 kernel()[0] <Notice>: wlan0:com.apple.p2p: setScanningState:: Scan request from ScanManagerFamily.

Simply opening Simulator app (26.0) causes high CPU usage on macOS Tahoe (26.1). ReportCrash process usage is very high throughout and causes the system to heat up pretty soon. Looking into Console app for the logs found MercuryPosterExtension process is keep on crashing. (Check under Crash Reports) simctl Diagnose https://download.developer.apple.com/OS_X/OS_X_Logs/simctl_Diagnose_Logging_Instructions.pdf Share the Simulator Diagnose report while reporting, Thanks. I have raised a ticket/feedback with Apple. I request all of you to raise one too so this gets fixed soon. Apple Feedback Assistant - FB20985249

I’m trying to use EXR lightmaps to overlay baked lighting on top of a base texture in the RCP Shader Graph. When I multiply an EXR image set to Image(float) with an 8-bit base texture, the output becomes Image(float). I can’t connect that to the BaseColor input on the UnlitSurface node, since it only accepts Color3f. I expected to be able to use a Convert node between the Multiply node and the BaseColor input, but when I do that, the result becomes black and white instead of the expected outcome: the EXR multiplied with the base texture using a baseline value of 1, where values below 1 in the EXR would darken the base texture and values above 1 would brighten it. Is there any documentation on how to properly overlay a 32-bit EXR lightmap in the RCP Shader Graph, or is the black-and-white output from the Convert node a bug?

I am constantly reaching my daily ChatGPT limit and even though it's recommending that I log in, I already am. What can I do to fix this?

Hi all, I'm trying to add Spotlight support to a macOS app that handles custom virtual machine bundles with the .vpvm extension. I’ve followed the current documentation and used the modern CSImportExtension approach with a Spotlight Importer extension target. Here’s what I’ve done: App Info.plist: Declared com.makeprog.vpvm as a UTI conforming to com.apple.package. Registered it under UTExportedTypeDeclarations and CFBundleDocumentTypes. Spotlight Importer Extension: Added a new macOS target using the Spotlight Import Extension template. Set the NSExtensionPointIdentifier to com.apple.spotlight.import. Used CSSupportedContentTypes = com.makeprog.vpvm. Implemented a minimal update(_ attributes:forFileAt:) method that sets displayName, title, and contentDescription. Other steps: Verified that the .appex is embedded under Contents/PlugIns/. Confirmed it appears in mdimport -e output with correct UTI. Used mdimport -m -d2 -t /path/to/file.vpvm, but I still get: Imported '/path/to/file.vpvm' of type 'com.makeprog.vpvm' with no plugIn. The extension is never invoked. I’ve also tried: Ensuring the .vpvm file is a valid directory bundle. Restarting Spotlight / rebuilding index. Ensuring the app and extension are properly signed. Tried installing the app in test virtual machine Question: Has anyone successfully used CSImportExtension for custom UTIs? Is there something additional I need to do for the extension to be recognized and triggered? Any advice or examples would be greatly appreciated! Thanks in advance.

I’m seeing unexpected scroll behavior when embedding a LazyVStack with dynamically sized views inside a ScrollView. Everything works fine when the item height is fixed (e.g. colored squares), but when I switch to text views with variable height, the scroll position jumps and glitches—especially when the keyboard appears or disappears. This only happens on iOS 26, it works fine on iOS 18. Working version struct Model: Identifiable { let id = UUID() } struct ModernScrollView: View { @State private var models: [Model] = [] @State private var scrollPositionID: String? @State private var text: String = "" @FocusState private var isFocused // MARK: - View var body: some View { scrollView .safeAreaInset(edge: .bottom) { controls } .task { reset() } } // MARK: - Subviews private var scrollView: some View { ScrollView { LazyVStack { ForEach(models) { model in SquareView(color: Color(from: model.id)) .id(model.id.uuidString) } } .scrollTargetLayout() } .scrollPosition(id: $scrollPositionID) .scrollDismissesKeyboard(.interactively) .defaultScrollAnchor(.bottom) .onTapGesture { isFocused = false } } private var controls: some View { VStack { HStack { Button("Add to top") { models.insert(contentsOf: makeModels(3), at: 0) } Button("Add to bottom") { models.append(contentsOf: makeModels(3)) } Button("Reset") { reset() } } HStack { Button { scrollPositionID = models.first?.id.uuidString } label: { Image(systemName: "arrow.up") } Button { scrollPositionID = models.last?.id.uuidString } label: { Image(systemName: "arrow.down") } } TextField("Input", text: $text) .padding() .background(.ultraThinMaterial, in: .capsule) .focused($isFocused) .padding(.horizontal) } .padding(.vertical) .buttonStyle(.bordered) .background(.regularMaterial) } // MARK: - Private private func makeModels(_ count: Int) -> [Model] { (0..<count).map { _ in Model() } } private func reset() { models = makeModels(3) } } // MARK: - Color+UUID private extension Color { init(from uuid: UUID) { let hash = uuid.uuidString.hashValue let r = Double((hash & 0xFF0000) >> 16) / 255.0 let g = Double((hash & 0x00FF00) >> 8) / 255.0 let b = Double(hash & 0x0000FF) / 255.0 self.init(red: abs(r), green: abs(g), blue: abs(b)) } } Not working version When I replace the square view with a text view that generates random multiline text: struct Model: Identifiable { let id = UUID() let text = generateRandomText(range: 1...5) // MARK: - Utils private static func generateRandomText(range: ClosedRange<Int>) -> String { var result = "" for _ in 0..<Int.random(in: range) { if let sentence = sentences.randomElement() { result += sentence } } return result.trimmingCharacters(in: .whitespaces) } private static let sentences = [ "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.", "Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.", "Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.", "Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum." ] } and use it like this: ForEach(models) { model in Text(model.text) .padding() .multilineTextAlignment(.leading) .background(Color(from: model.id)) .id(model.id.uuidString) } Then on iOS 26, opening the keyboard makes the scroll position jump unpredictably. It is more visible if you play with the app, but I could not upload a video here. Environment Xcode 26.0.1 - Simulators and devices on iOS 26.0 - 18.0 Questions Is there any known change in ScrollView / scrollPosition(id:) behavior on iOS 26 related to dynamic height content? Am I missing something in the layout setup that makes this layout unstable with variable-height cells? Is there a workaround or recommended approach for keeping scroll position stable when keyboard appears?

Hello Apple Developer Community, I'm experiencing an issue with file download functionality in the iOS Simulator after updating to Xcode 26 RC (Build 17A321). Issue Description: When attempting to download files in the iOS Simulator via Safari, the download prompt appears correctly, but after tapping the 'Download' button, files are not being saved to the Files app. The download appears to do nothing with no error message, no indication of failure, but the file simply doesn't appear in Downloads or anywhere in the Files app. Environment: Xcode Version: 26.0 RC (17A321) iOS Simulator Version: 26.0 RC (23A339) Device Simulated: iPhone Air Steps to Reproduce: Open Safari in the iOS Simulator Navigate to a downloadable file (PDF, ZIP, etc.) Tap to initiate download Download prompt appears as expected Tap the 'Download' button Check the Files app → Downloads folder (empty) Expected Behavior: Files should download normally as they do on physical devices and as they did in previous Xcode versions. Actual Behavior: The download prompt dismisses after tapping 'Download', but no file appears in the Files app. No error message is shown, and there's no indication that the download failed, it simply appears as if nothing happened. Additional Information: Downloads work correctly on physical device (iOS 26 RC 23A340) This functionality worked properly in previous Xcode versions I have created a bug report to Feedback assistant: FB20190927 Thanks in advance for any assistance.

I am trying to use the new SpeechAnalyzer framework in my Mac app, and am running into an issue for some languages. When I call AssetInstallationRequest.downloadAndInstall() for some languages, it throws an error: Error Domain=SFSpeechErrorDomain Code=1 "transcription.ar asset not found after attempted download." The ".ar" appears to be the language code, which in this case was Arabic. When I call AssetInventory.status(forModules:) before attempting the download, it is giving me a status of "downloading" (perhaps from an earlier attempt?). If this language was completely unsupported, I would expect it to return a status of "unsupported", so I'm not sure what's going on here. For other languages (Polish, for example) SpeechTranscriber.supportedLocale(equivalentTo:) is returning nil, so that seems like a clearly unsupported language. But I can't tell if the languages I'm trying, like Arabic, are supported and something is going wrong, or if this error represents something I can work around. Here's the relevant section of code. The error is thrown from downloadAndInstall(), so I never even get as far as setting up the SpeechAnalyzer itself. private func setUpAnalyzer() async throws { guard let sourceLanguage else { throw Error.languageNotSpecified } guard let locale = await SpeechTranscriber.supportedLocale(equivalentTo: Locale(identifier: sourceLanguage.rawValue)) else { throw Error.unsupportedLanguage } let transcriber = SpeechTranscriber(locale: locale, preset: .progressiveTranscription) self.transcriber = transcriber let reservedLocales = await AssetInventory.reservedLocales if !reservedLocales.contains(locale) && reservedLocales.count == AssetInventory.maximumReservedLocales { if let oldest = reservedLocales.last { await AssetInventory.release(reservedLocale: oldest) } } do { let status = await AssetInventory.status(forModules: [transcriber]) print("status: \(status)") if let installationRequest = try await AssetInventory.assetInstallationRequest(supporting: [transcriber]) { try await installationRequest.downloadAndInstall() } } ...

I have two feedbacks now where I’ve been requested additional info, and provided it, but the feedback still has an “unread” dot, and is still in the “Requests” folder. I’ve asked multiple times to clear this status in one of those feedbacks (FB14888965), but got no response. Not the end of the world as long as the engineers are notified, but iirc the dot would disappear as soon as I replied.

But, we are utilizing information contained in the points/features collected by ARKit. Currently, the range of rawfeaturepoints is limited to about 10 meter from the device. We see a great chance if the range is unlock. The global localization will be more robust and accurate. ARPointCloud - Apple ARKit - FindSurface YouTube SIdQRiLj2jY

Hello Apple Developer Support, I’m writing with a mix of enthusiasm and frustration after more than six months of full‑time development on my macOS window‑manager TilesWM (a feature‑rich competitor to Magnet, Divvy, BetterSnapTool, etc.). I have completed the Application, the product page, a knowledge-base with 90+ entries, an in-app onboarding flow, preparing the feedback-hub for submissions, all required marketing assets and finally; signing up for the $99 Developer Program... I am now blocked at App Store Connect validation. What I’m trying to submit App name: TilesWM Bundle ID: dev.steinhorst.tileswm Core functionality: Detect window movement & resize windows, optional global hot‑keys, persistent user settings are stored in a SQLite-DB located at: ~/Library/Application Support/<bundle‑identifier> Privacy: No analytics, no data collection, no runtime downloads. Tested on: macOS 15.6.1 (Apple Silicon M1) & macOS 26.0.1 (M3‑Max). The app works exactly like the existing mainstream window managers: it runs non‑sandboxed and requests Accessibility (AX) permissions on demand to control other windows dimensions and positioning. Validation errors Validation failed Invalid Code Signing Entitlements. Your application bundle's signature contains code signing entitlements that are not supported on macOS. Specifically, key 'com.apple.security.accessibility' in 'dev.steinhorst.tileswm.pkg/Payload/TilesWM.app/Contents/MacOS/TilesWM' is not supported. (ID: 13b13813-edd6-4be6-b392-9db5bddd39a0) Validation failed App sandbox not enabled. The following executables must include the "com.apple.security.app-sandbox" entitlement with a Boolean value of true in the entitlements property list: [( "dev.steinhorst.tileswm.pkg/Payload/TilesWM.app/Contents/MacOS/TilesWM" )] Refer to App Sandbox page at https://developer.apple.com/documentation/security/app_sandbox for more information on sandboxing your app. (ID: 28aa17e8-e7b2-4f3f-8def-15922c68ec8a) . In short, App Store Connect refuses to accept an app that uses the Accessibility API and is not sandboxed. Yet the same capability is openly used by Magnet, Divvy, BetterSnapTool and other competitors that are currently on the Mac App Store. Why this matters to me I am a full‑stack engineer with 15+ years of enterprise experience; side projects keep my skills sharp and give back to the macOS community. This would be my entry to the software-side of MacOS, the next product-ideas are scribbled already. Over the last six months I have designed, coded, documented, created marketing assets, purchased a domain, paid for hosting, and funded the Apple Developer Program, all in good faith that the app could be submitted. What I need help with Clarification – Is the com.apple.security.accessibility entitlement truly unsupported for macOS distribution, how can Magnet and other competitors exist in that case, shouldn't they be able to receive competition? Guidance – If sandboxing is mandatory (even though the competition doesn't use it either, looking at their entitlements with codesign -d --entitlements :-<path>). What is the recommended way to retain full window‑management functionality while remaining within Apple’s policies, I tried sandboxing it, but the only app I was able to "resize" was TilesWM (my App) itself. Additional resources A "basic"-demo video, feature comparisons, FAQ & knowledge-base as well as the feedback hub: https://www.tileswm.app I appreciate any insight you can provide. My goal is to bring a polished, useful tool to the Mac App Store while fully respecting Apple’s security requirements, without having to discard months of work or resort to an external distribution model. Thank you for your time and assistance. Best regards, Denis Steinhorst Full‑Stack Engineer – macOS enthusiast Bundle ID: dev.steinhorst.tileswm

Hello, I am having a recurring issue using Swift Playgrounds version 4.6.4 on macOS 26.1. Upon opening a file and every other time I start typing in the code section I get a prompt, the image below, two or three times. It doesn't matter if I accept or decline all or some of the prompts, as soon as I start typing on another line I get prompted another two or three times for permission. It appears to me that prompt generates every time the preview pane tries to update. Declining the prompt breaks the preview but accepting the prompt only gets you through a single line of code before it appears again. I believe this issue started after I updated to macOS26.1 as I had not encountered it before. I've also opened other files with Swift Playgrounds and encounter the same problem. It could also be unrelated to the update and could be an issue with some permission setting somewhere, however, I have been unable to find what or where it could be. Is anyone else experiencing this? Thank you for your time :)

I'm unable to sign in to Feedback Assistant on macOS. I have two Apple accounts and neither will sign in. I am able to sign in via the website.

Hello, We are experiencing an issue with the notarization queue and would appreciate your assistance. A few days ago, we helped another team submit their app for notarization. However, that submission has been stuck in the “In Progress” state for about three days now. Unfortunately, this also seems to have caused our own team’s notarization requests to get stuck as well. We ran the following command to review the submission history: xcrun notarytool history --apple-id "xxx" --team-id "xxx" --password "xxx" Successfully received submission history. Partial results: id: 0bafa66f-4f47-4327-811f-a05481be5d0b status: In Progress id: 2d00b75a-a17a-44fc-afa1-71e0e39ec2cd status: In Progress It appears that one of these belongs to another team’s app we helped submit, and the other is our own submission. Both have remained In Progress for several days, and we are now unable to proceed with any new notarization requests.

Hi, I’ve built an app that includes a Contacts Provider Extension (CPE). On iOS 18, I observed the expected behavior — when the main app is uninstalled, the corresponding CPE entry is also removed from the Contacts list. However, on iOS 26, this no longer happens. After uninstalling the app, the CPE remains visible and active in the Contacts list, even though the app is gone.

After the macOS Sequoia update, my app seems to have an issue with Bluetooth communication between macOS and iOS that uses CoreBluetooth for Central-Peripheral communication. Setup: The iPhone (in my case: iPhone 14 Pro with iOS 18.0 (22A3354)) acts as the Central, and the Mac (in my case: 14" MacBook Pro 2023 with macOS 15.0 (24A335)) as the Peripheral. I’ve implemented a mechanism where the Central (iPhone) sends a message to the Peripheral (Mac) every 15 seconds to keep the connection alive (Because it needs to wait for notify characteristic updates). I never noticed this kind of issue before, but with macOS Sequoia I get it permanently. Issue: The connection drops unexpectedly after a period of time (sometimes 20 seconds, sometimes a few minutes) with CBErrorDomain - code 6: The connection has timed out unexpectedly. Sample Code: Peripheral (Mac): ContentView (Peripheral).txt ContentViewModel (Peripheral).txt Central (iPhone): ContentView (Central).txt ContentViewModel (Central).txt Reproduce: I attached sample code including the Central-Sample (for iPhone) and Peripheral-Sample (for Mac). Just run the Peripheral-Sample (after granting Bluetooth permissions). Then run the Central-Sample and select the Mac device in the list After selecting it should connect, discover the service & characteristic and should start writing messages to it. After some time the func centralManager(_ central: CBCentralManager, didDisconnectPeripheral peripheral: CBPeripheral, error: (any Error)?) {should get called with timed out unexpectedly error. Could anyone please look into this issue and advise on whether there’s a known bug or any workaround? Any guidance would be greatly appreciated, as this impacts the stability of Bluetooth communication between the devices. Thanks in advance. Logs: I also ran the console.app during this issue which got these errors (if this is helpful): console_logs.txt

Hi Team, I want to perform bluetooth advertising (no need to pair) from a macOS machine even before the user login to the macOS(i.e before user provide password and submit). Is there a way to achieve this?

Hi all. My adapter model just won't invoke my tool. The problem I am having is covered in an older post: https://developer.apple.com/forums/thread/794839?answerId=852262022#852262022 Sadly the thread dies there and no resolution is seen in that thread. It's worth noting that I have developed an AI chatbot built around LanguageModelSession to which I feed the exact same system prompt that I feed to my training set (pasted further in this post). The AI chatbot works perfectly, the tool is invoked when needed. I am training the adapter model because the base model whilst capable doesn't produce the quality I'm looking for. So here's the template of an item in my training set: [ { 'role': 'system', 'content': systemPrompt, 'tools': [TOOL_DEFINITION] }, { 'role': 'user', 'content': entry['prompt'] }, { 'role': 'assistant', 'content': entry['code'] } ] where TOOL_DEFINITION = { 'type': 'function', 'function': { 'name': 'WriteUbersichtWidgetToFileSystem', 'description': 'Writes an Übersicht Widget to the file system. Call this tool as the last step in processing a prompt that generates a widget.', 'parameters': { 'type': 'object', 'properties': { 'jsxContent': { 'type': 'string', 'description': 'Complete JSX code for an Übersicht widget. This should include all required exports: command, refreshFrequency, render, and className. The JSX should be a complete, valid Übersicht widget file.' } }, 'required': ['jsxContent'] } } ... and systemPrompt = A conversation between a user and a helpful assistant. You are an Übersicht widget designer. Create Übersicht widgets when requested by the user. IMPORTANT: You have access to a tool called WriteUbersichtWidgetToFileSystem. When asked to create a widget, you MUST call this tool. ### Tool Usage: Call WriteUbersichtWidgetToFileSystem with complete JSX code that implements the Übersicht Widget API. Generate custom JSX based on the user's specific request - do not copy the example below. ### Übersicht Widget API (REQUIRED): Every Übersicht widget MUST export these 4 items: - export const command: The bash command to execute (string) - export const refreshFrequency: Refresh rate in milliseconds (number) - export const render: React component function that receives {output} prop (function) - export const className: CSS positioning for absolute placement (string) Example format (customize for each request): WriteUbersichtWidgetToFileSystem({jsxContent: `export const command = "echo hello"; export const refreshFrequency = 1000; export const render = ({output}) => { return <div>{output}</div>; }; export const className = "top: 20px; left: 20px;"`}) ### Rules: - The terms "ubersicht widget", "widget", "a widget", "the widget" must all be interpreted as "Übersicht widget" - Generate complete, valid JSX code that follows the Übersicht widget API - When you generate a widget, don't just show JSON or code - you MUST call the WriteUbersichtWidgetToFileSystem tool - Report the results to the user after calling the tool ### Examples: - "Generate a Übersicht widget" → Use WriteUbersichtWidgetToFileSystem tool - "Can you add a widget that shows the time" → Use WriteUbersichtWidgetToFileSystem tool - "Create a widget with a button" → Use WriteUbersichtWidgetToFileSystem tool When the script that I use to compose the full training set is executed, entry['prompt'] and entry['code'] contain the prompt and the resulting JSX code for one of the examples I'm feeding to the training session. This is repeated for about 60 such examples that I have in my sample data collection. Thanks for any help. Michael
