Cupertino moved to Codeberg.

The SwiftUI Oracle: Measuring a Clean Room Against the Real Thing In the last post I claimed I had measured SwiftUI until its behavior was predictable.

SwiftUI Is One Graph, Over 40+ Years of Engineering I wanted to know what SwiftUI really is, not what the tutorials say it is.

Indistinguishable From an Attack An autonomous bounty bot opened a pull request on my project that quietly repointed a core dependency to a fork it controlled.

The rules my AI coding agent is not allowed to break Left to its own defaults, an AI coding agent is an enthusiastic shortcut machine.

Validations Are Values Here is the validation function almost everyone writes the first time.

Swift Runs Everywhere.

Cupertino v1.0.2: the duplicate that LOWER(uri) could not see A few weeks ago I shipped cupertino v1.0.1 and closed the bug that was supposed to make it impossible for the same Apple page to appear twice in the local search index.

Cupertino v1.0.0 “First Light” The first release I’d actually call stable.

iRelay: Text Your Mac, Run an AI Agent I created a GitHub repo from my phone while walking around the house.

Cupertino: Offline Apple Documentation for AI Agents TL;DR: I built an MCP server that gives Claude Desktop offline access to 22,000+ Apple documentation pages across 261 frameworks.

Authentication is one of those things that every API client needs, yet implementing it cleanly and safely can be surprisingly tricky—especially in Swift’s modern concurrency world.

When I first published ExtremePackaging, the goal was simple — to prove that highly modular Swift architectures can scale across platforms while keeping build times fast, dependencies isolated, and the mental model crystal clear.

Introduction In the world of OpenAPI-driven Swift servers, visibility is everything.

A Modular Architecture Methodology for Swift Projects By Mihaela Mihaljevic Introduction Extreme Packaging is a methodology for structuring Swift projects with maximal modularity and minimal responsibility per module.

CVBuilder is a powerful Swift package that I developed to solve a common problem: managing and rendering professional CVs in multiple formats.

When I first discovered SwiftUILab’s Advanced Animations, I was impressed by the beautiful animations and transitions it demonstrated.

I’ve been researching Core Animation framework for the past few months.
