I'll be a mentor at this year's Swift Island in Texel! 🦭 Super excited to hang out with everyone in September. Hope to see you there! swiftisland.nl/mentors

I have encountered the term "full actor isolation" numerous times lately. I find this vexing.

Swift Effect is now in public preview! it is an architecture-agnostic effect system that makes side effects (such as I/O, networking, randomness, concurrency) controllable, composable, and testable without forcing structural changes to your application code. github.com/Alex-Ozun/sw... #swiftlang

Happy Morning Gang! Just thought I'd share that I remain very not into Apple actively supporting the destruction of democracy worldwide in exchange for a favorable regulatory environment.

Finished The Pedestrian. Incredible creativity with some difficult puzzles. Fun, interesting, surprising, on the short side. Next up: Pirate Outlaws

There is an intense discussion going on in the house and I have now staked my reputation on Lego releasing a Borg cube.

Excited to share Peak 5, a big update for my fitness tracking app! 🧩 New dashboard with grouping and filtering! 🎨 Liquid Glass design and icons 💨 Fast as hell This app has been so important for me in my own fitness journey, and I really hope it can be the same for you too

"Whoops. There I go again getting mixed up between making something good and making it profitable. Apologies."

I keep running into Swift packages that use versioned manifests and I decided to have feelings about it. www.massicotte.org/blog/packa...

I'm a complete LLM outsider - never written a prompt. But I believe people when they share their experiences. And the variety of those experiences is absolutely mind boggling to me.

Taking a break from the grown up game (Witcher 3), trying The Pedestrian. *Incredibly* creative concept.

"with great reach comes great responsibility" or something like that

This is a very valuable message and worth thinking about. For AI, yes, for sure. But also more broadly too. https://mister.computer/@kyle/115775710250060682

The two hardest problems in Computer Science are 1. Human communication 2. Getting people in tech to believe that human communication is important

debit, credit debt, cred debibility, credibility hope this helps

Almost a year to the date of my last *new* app release, SingTheSong is now out on visionOS! I'm still building apps for visionOS because it's FUN. This one listens to the music playing in your environment and displays real-time lyrics. Made this one for my fellow vinyl enthusiasts.

I'm trying to come up with a good joke about Stockholm Syndrome, but honestly, I'm starting to think maybe it's just really misunderstood and not so bad after all

I was speaking with someone struggling terribly with Swift. They shared two summaries from Claude along the way. One even had a quote from me (!!). A remarkable combination of right, wrong, and totally unhinged. Still shook.

Mark your calendars for July 2026 because we have another conference in this hemisphere of the world friends! No other than Calgary, Canada! And in the amazing rockies next to the national park Banff 🇨🇦 🏔️🌊 swiftrockies.com

After a number of truly awful attempts, I have a post about "Non-Sendable First Design" that I think I can live with. I like this approach and I think you might like it too. It's simple, flexible, and most importantly, it looks "normal". www.massicotte.org/blog/non-sen...

If you are into this kind of thing, I recommend checking out Sia's Everyday is Christmas. The whole thing is quality. "It's Christmastime so run for your lives oh hallelujah"

Working on a bug, no clue what was going on. Was about to give up for the day, which always really bothers me. But! At the last second I figured out *what* was happening! So now I am, of course, bothered by *why* it's happening…

Swift compiler: you must now document how your APIs actually work API owners:<flips table> how many times do I have to tell you no one knows how they actually work

Ohh. I didn't notice earlier, but it looks like UndoManager's API now actually makes sense in the 26 SDKs.

🚀 I’ve been working on this project just for fun, and I’m happy to share that it’s now open source. ✨ SF Symbols Lite is a lightweight, fast alternative to Apple’s SF Symbols app, focused on better search, custom tags, and a clean macOS experience. ✨ macOS 26. ❤️ ☛ github.com/ruiaureliano...

My new hobby: looking at CLAUDE.md, Package.swift, glancing around at the code, and having Opinions

There's a great joke about cancel culture and structured concurrency but I haven't quite figured it out, someone help me out here

I'm going to try to make "syntactic salt" happen

I'm very excited to have a first beta out of a new SDK that I so far call MediaKit (I regret the name already). The idea is to make it super simple to create streaming media apps with Swift and SwiftUI. It's is so far pretty simple, but I look forward to working on it. github.com/Kankoda/Medi...

A second attempt at writing today resulted in 0 (zero) things worth reading. It's fun sharing my process of producing garbage though.

The Swift subreddit is incredibly good… … at trying my patience

Do we have a name for trying to do something with AI and failing in a spectacular and extremely obvious way that makes it clear you spent no time on it? Is that still slop? Maybe flop?

I wrote this post nearly 5 years ago. I'm still a SwiftUI beginner. But I also still think capturing a "parent" in a coordinator is questionable. www.massicotte.org/swiftui-co...

Ok who else knew about this subscript(_enclosingInstance) stuff??? www.swiftbysundell.com/articl...

Substack is being very tentative to start, but I'd be shocked if this doesn't end in mandatory programmatic ads attached to all free Substack posts

I have consistently seen better design and branding from random independent coffee shops than from any large company. Just putting them to shame.

Does anyone know where the "if someone says something is complicated, then it is" idea came from? I picked it up a while ago and love it, but I cannot recall where I found it.

Did a little writing. Read it over. Absolutely hated everything about it. And with that, the day is done.

It's fascinating to look though AGENTS.md and other similar kinds of LLM context stuff geared towards Swift.

Yes, sure, things look like they aren't going so great for Apple's executives lately. But I'm sure that you, a rank-and-file employee, can think of some perfectly legal thing to do, or not do, that could make it just a tiny bit worse.

Ever had that person where every interaction just ends up awkward. And you don’t know how it’s possible but then bad luck strikes, it somehow happens again. And you grab them by the shoulders, shaking them saying “I’M NOT ACTUALLY LIKE THIS I AM NOT WEIRD I’M VERY NORMAL”

You ever see a product and think “this is so weird and such a bad idea and … I think I’m going to buy it”?

Swift compiler settings are a critical part of your project configuration. I took some time to take stock of the current situation, including some (light) recommendations. www.massicotte.org/blog/what-se...

"I forgot that I forgot that. But now that I remember I forgot, I wish I could forget"

I just received a letter from Volkswagen saying that a (dealer-installable only) software update will be available for my ID.4 to address four specific issues all of which are brutal and I hit regularly. I seriously thought the day would never come.

Ahh and there is it. A US bill that would strip me and my son of our citizenships. I knew this was coming, and isn’t passed yet. But still.

Regardless of how you feel about passkeys, 2FA, or password stuff in general I think we can all agree that it’s good every financial institution has invented their own custom solution
