We built SwiftAI, an open-source Swift library that lets you use Apple’s on-device LLMs when available (Apple opened access in June), and fall back to a cloud model when they aren’t available — all without duplicating code. SwiftAI gives you: - A single, model-agnostic API - An agent/tool loop - Strongly-typed structured outputs - Optional chat state Backstory: We started experimenting with Apple’s local models because they’re free (no API calls), private, and work offline. The problem: not all devices support them (older iPhones, Apple Intelligence disabled, low battery, etc.). That…

Hey, A few weeks ago I randomly decided to build a seamless pattern engine for Swift/SwiftUI projects. I called it Tessera (GitHub link). It’s an open-source framework that lets you generate endlessly repeatable, seam-free patterns from pretty much anything you can build in code: shapes, SF Symbols, emojis, text, custom icons, etc. While working on it, I also built a demo app so developers could see how to use the framework. However, that demo turned out to be so much fun to play with that I decided to turn it into a full app. ## Introducing Tessera Designer Tessera Designer is a Mac…

hi everybody, I’ve been working on this harness that is all native Swift for macOS. It’s fully featured with every feature i could find in cline, codex, and claude code. There is all swift command line too It’s taking me a long, long time, a few months to build this, and it’s fully open source Apache 2 licensed. Hoping people fork this and make many branches I’m looking for people who want to work on something that has much lower memory usage and much more potential to be just more efficient. Every other single harness has is written in using electron, so this harness is really unique in…

We recently started to use agents to update some documentation across our codebase on a weekly basis, and everything quickly turned into cron jobs, logs, and terminal output. it worked, but was hard to tell what agents were doing, why something failed, or whether a workflow was actually progressing. We thought it would be more interesting to treat agents as long-lived workers with state and responsibilities and explicit handoffs. Something you can actually see and reason about, instead of just tailing logs. So we built Clawe, a small coordination layer on top of OpenClaw that lets agent…

I have created a Swift package (https://github.com/daspoon/tree-sitter-kit) enabling tree-sitter parsers to be written in Swift; specifically, as an array of production rules which map symbol types to pairings of syntax expression and type constructor. A member macro derives a tree-sitter grammar and embeds the generated parser in its expansion. This project is a work in progress, and I will be grateful for any feedback. Thanks, Dave

Hey HN – Stefan and Elijah here from DAGWorks (http://dagworks.io/, YC W23). If you don’t remember us from our previous HN launch (https://news.ycombinator.com/item?id=35056903), we’re the authors of Hamilton (https://github.com/dagworks-inc/hamilton), an open-source library for building self-documenting, modular dataflows in python that works for data, ML, LLM pipelines, & even web-workflows. We’ve been developing this UI for a while and we’re excited to say we open-sourced it! It comes out of the box with the following capabilities, and…

Hi HN, I'm a 19-year-old aerospace student. I spent the last 13 months building a custom Linux distro from scratch because I wanted to see if we could treat the OS kernel as a mathematical engine rather than a deterministic administrator. The Stack: Flux (The Shell): A custom math-native shell where x² and ∑ are valid syntax. It parses mathematical notation directly into optimized SIMD instructions (no Python wrapper). Tenet (The Scheduler): Written in Tenet (my custom DSL for game theory). The scheduler is a Nash Equilibrium solver compiled to native code. In my benchmarks (Ryzen 7 5800HS),…

Q12 is a new web-based 2D parametric drawing tool built specifically for geometric problem solving, for playing interactive "what if" games with drawings, and for the design and optimization of mechanisms. Q12 has the usual set of drawing constraints found in other CAD tools (e.g. "lines are parallel") but also supports inequality constraints, area constraints, and arbitrary expressions between geometric quantities. We built Q12 to solve problems like those below, after finding that existing CAD systems couldn't handle them well: * Given dimensions on a surveyor's map, figure out if the…

Hey everyone! I made a Mac app for exploring large language models. It’s fast, small, has a tiny memory footprint. It’s immutable by design with both immediate time travel and automatic versioning as foundational elements. The app is written in Swift and a bit of Rust for the tokenizer. I used SwiftUI for structure and animations and Cocoa for advanced behavior. All storage is SQLite and local-only. You can go through the database as needed and backup it as well. The app has support for variants, which is the `n` parameter in the OpenAI chat completion API—equivalent to the drafts feature in…
