@karpathy If anyone is interested to run "autoresearch" on an Nvidia Jetson Orin Nano (more for education purposes than speed) here is a PR: github.com/karpathy/autor…
English

I packaged up the "autoresearch" project into a new self-contained minimal repo if people would like to play over the weekend. It's basically nanochat LLM training core stripped down to a single-GPU, one file version of ~630 lines of code, then:
- the human iterates on the prompt (.md)
- the AI agent iterates on the training code (.py)
The goal is to engineer your agents to make the fastest research progress indefinitely and without any of your own involvement. In the image, every dot is a complete LLM training run that lasts exactly 5 minutes. The agent works in an autonomous loop on a git feature branch and accumulates git commits to the training script as it finds better settings (of lower validation loss by the end) of the neural network architecture, the optimizer, all the hyperparameters, etc. You can imagine comparing the research progress of different prompts, different agents, etc.

Part code, part sci-fi, and a pinch of psychosis :)

@NathanBLawrence @Baconbrix An issue I found: As Xcode uses its own MCP tools for list, read, write etc the permissions (allow/deny) set in .claude/settings.json are entirely ignored. Any workaround for this as there is no permission system for MCP yet?
English

@Baconbrix We us the Claude Agent SDK, with full blessing from Anthropic: anthropic.com/news/apple-xco…
English

@machinamentum Agreed. Also problematic: Xcode's MCP tools bypass Claude Code's settings.json permissions entirely for file operations.
English

The agentic coding addition to Xcode 26.3 looks disappointing. I would really have liked to see an Apple-made offline model that doesn’t require paying a sketchy AI company and uploading parts of your private code to their servers

@mikeyk Nice work! There seems to be an oversight though: Since Xcode uses its own MCP tools (mcp__xcode-tools) for ls, read, and write operations, the permissions set in settings.json aren't respected. Any workaround for this, given there's no MCP permissions system yet?
English

Xcode 26.3 launched today with a native integration with the Claude Agent SDK, the same harness that powers Claude Code.
Devs get the full power of Claude Code (subagents, background tasks, and plugins) for long-running, autonomous work directly in Xcode 🤖

@ian_mcdowell @mgorbach FB13711844 demonstrates the issues. Any ideas for workarounds more than welcome:)
English

@ian_mcdowell @mgorbach on a further note in the extact.actionsdata file the AppIntents are correctly annotated regarding iOS version availably, but there is no such information for the AppShortCuts.
English

@ian_mcdowell @mgorbach Is there a way to make AppShortCuts that reference AppIntents that are only for iOS 17 not appear on iOS 16? Both are annotated with only avail. on iOS 17, but this seems to be ignored by the metadata extractor.
English

@mgorbach @ian_mcdowell I hope it was possible to reproduce the issue-
Something else: Is it possible to use the property of an AppEntity in the When clause for the ParameterSummary? I am however getting compile errors that the entity property does not conform to AnyIntentValue, though being annotated.
English

@ian_mcdowell @holtmann Hi, do you mind adding to your bug an example project that reproduces the issue?
English

@ian_mcdowell Latest Xcode/swift compiler has a pretty serious regression affecting AppIntents/AppShortcuts on iOS 16 devices. Please see: FB13664020
English

@mgorbach @ian_mcdowell I’ve just attached a sample project to FB13664020

@jordibruin The native interface often runs into timeouts, when the expected answer is long (e.g. write a python program…). Suggestion: Increase the timeout for the http request or make use of the stream feature of the API and on the client side use something like github.com/launchdarkly/s…

Reading the @viticci iOS 16 review and I no idea this new interaction existed. When batch selecting, if you try to bring up a context menu on any of the items - you get this rad interaction grouping them together.
Is there new API for this, or do you just get it for free?
English

@timroesner Thanks for the quick reply. Did a quick test in a custom app and the default behaviour seems to be that all selected cells are used for the UIContextMenuContentPreviewProvider as stacked imaged preview. I am also getting the slow performance when many items are selected.
