I had a great time chatting with @younata.hachyderm.io.ap.brid.gy about what's new in Swift Testing. If you are looking to learn about what's coming to Swift soon, check this episode out.

Here are the 2 tools I use to stay productive every week:
* @BearNotesApp for my daily goals
* @Apple #Numbers for my weekly goals (one week per sheet)
I can't believe I've been doing this for 6 years and still haven't built my own todo app as a replacement. 😅

So I wasn’t planning on buying physical games for the Switch 2 but if I buy something for the kids for Christmas ahead of time it’d have to be right? 🤷♂️

Just released SyntaxKit - a declarative DSL for Swift code generation
I went from attempting to train a custom LLM to successfully using Cursor and @anthropic.com's Claude Code for iterative development.
Perfect for anyone building code generation tools.

Just completed a full rewrite of MistKit – my Swift Package for server-side and command-line CloudKit Web Services!
This time I used AI to generate an OpenAPI document for the API, then built abstractions on top. Article coming soon on the rebuild process.

Working on a developer conference talk about AI adoption journeys.
The theme: most of us went from "this is overhyped" to "oh no, p-doom" to "actually, this is pretty useful for specific things."
How do we maintain healthy skepticism while embracing useful tools?
Anyone else speaking about AI?

My current AI development workflow:
• Claude Code for project-level management
• Cursor for focused iterations
• Regular human code reviews (AI makes mistakes)
• Clear constraints and examples

I've lived through: 3D printing, VR "this time it's different", crypto, self-driving cars "next year"
AI feels different because the tools actually work TODAY. Not perfect, but useful.
The question isn't "will AI take over?" It's "how do I use these effectively?"
