Rebuilt my server-side CloudKit library (MistKit) using Claude Code 12 months of work → 3 months with AI Here's how we turned Apple's 2016 REST API docs into modern type-safe Swift 🧵

It’s so beautiful! After a year and half I finished wiring my speakers and Ethernet! 😭🥲 Truly a piece of art!

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. 😅

I am excited to release Bushel 2.3.0 with a new "Glassy" icon and major bug fixes. mailchi.mp/8b1d66e20337...

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? 🤷‍♂️

Hey! It's been a while since I introduced myself. I'm Leo Dion, and I create content about software development in the Apple Space and Swift for Swift developers interested in growth and quirky tech topics. Whether you're new or have been around, I'm glad you're here.

How many switch case statements do you have before you refactor it into something else like a Dictionary?

Is there a use case for this if it crashes when there's no object? developer.apple.com/documentatio...

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. us12.campaign-archive.com?u=cb3bba007e...

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. github.com/brightdigit/...

I decided to use the LLM tools out there to simplify and abstract SwiftSyntax and build a DSL for creating code templates and Macros. It was an interesting experience to say the least and glimpse into the possibilities of these tools and their limitations. brightdigit.com/tutorials/sy...

Bought an EV and then I realized… We should design the colors for iPhone Pros

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 What's yours? Where do you see it fall short? Where do you need to step in?

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?"

Just published BrightDigit Newsletter Issue #114! This week I'm sharing swift-build - a GitHub Action I built after getting tired of copying the same complex Swift CI/CD configurations across every project. Zero-config testing across all platforms. mailchi.mp/1c8d2d69bca8...

Let's give a big hand to those remarkable people who selflessly shared their precious insights with us: Jared Sinclair, @donnywals.bsky.social , Kyrylo Hanichev, Kyle Ye, Mikhail Isaev, Mathis Gaignet, @leogdion.bsky.social and Darren Ford

Speaking of swift-build... Just released v1.3.0 with support for Windows! Start testing your Swift package in Windows today. Thanks to help from @compnerd.bsky.social on this one. github.com/brightdigit/...

The Vision Pro Killer! Sorry Apple www.forbes.com/sites/mitchw...

Alright fellow iOS devs... I've got a high schooler looking for a great study app. Any recommendations? preferably an indie app and not just another LLM frontend

I loved chatting with @kayathomas.is about her new app Milk Diary what the market is like for moms. Check out this episode to learn more: brightdigit.com/episodes/203...

Introducing swift-build: a versatile GitHub Action for building and testing Swift packages across various platforms. I've been using it for over a year and appreciate its simplicity. It supports multiple versions of Swift , Xcode, iOS, macOS, or Linux. brightdigit.com/tutorials/sw...

🎙️ New BrightDigit newsletter: ✅ @kayathomas.is on building MilkDiary with iOS 26 ✅ @younata.hachyderm.io.ap.brid.gy on Swift Testing in Swift 6.2 ✅ Community question: How are you using AI? ✅ SyndiKit added to Swift Source Compatibility List mailchi.mp/fe714d180a4b...

Does anyone use the Speech Analyzer instead of SiriKit? It's interesting to get @kayathomas.is perspective on the differences between the 2 and how each serves a different purpose. brightdigit.com/episodes/203...

Even though @kayathomas.is is an expert in notifications she used AlarmKit in her latest app Milk Dairy. It's been 5 years since she talked about Notifications on the show and it's interesting here why she's using AlarmKit instead. brightdigit.com/episodes/203...

I was so proud of myself for getting this one! I'm always surprised when I pick load my 7 yo save file and still get new moons.

Snapshot Testing is one way to test your UI but has issues. In the latest episode , @younata.hachyderm.io.ap.brid.gy and I talk about what's new in Swift Testing and how to testing your app login and your UI. brightdigit.com/episodes/202...

Proud to have my first Swift Package, SyndiKit added to the Swift Source Compatibility Test Suite! Check out the list for more details: www.swift.org/documentatio...

After half a decade, @kayathomas.is came back to tell me about her new motherhood-inspired app Milk Diary. She talks about using new APIs like Foundation Models, SpeechAnalyzer, and AlarmKit to handle the complex stuff other feeding apps miss. brightdigit.com/episodes/203...

Just launched the iOS Backend Selection Guide v1.0.0! 🎉 This tool helps iOS developers choose the best backend by addressing key questions: MVP vs. enterprise, platform support, and options like Vapor and AWS Lambda.

I am hoping issue handing traits come to fruition soon in Swift Testing. In the latest episode, @younata.hachyderm.io.ap.brid.gy talks about what it'll let us do. Interested in the future of Swift Testing, check this latest episode out: brightdigit.com/episodes/202...

Kaya Thomas returns after 5 years to discuss her new app, Milk Diary. As a new mom, she focuses on creating a comprehensive baby feeding app. We explore her inspiration, iOS 26 development, Liquid Design, and Foundation Models. www.patreon.com/posts/milk-d...

I was sick of my hard drives getting full with old 26.0 simulator runtimes whenever I upgraded to a new beta. So I used some LLM magic to create a bash script to delete old betas. Give it a try: gist.github.com/leogdion/0bc...

Exit tests sound really cool. As a macOS and server-side dev, this would be really useful. It'd be cool to see it on other platforms too. Check out the latest episode with @younata.hachyderm.io.ap.brid.gy to learn what they are and how they can be helpful to you. brightdigit.com/episodes/202...
