📝 New series: Type-Driven Design with Swift! I've been working hard over the past few weeks to bring this material to life. The topic of Type-Driven Design is very near and dear to me because it's had a massive impact on my Swift programming mindset. https://t.co/QAony88VQ4

Hey look what just dropped! A recording of my recent talk from @iOSKonf ! The recording didn't capture the stage camera's feed, but that's totally fine because I have a radio face anyway 🫥 #swift #swiftui #swiftlang #ios https://t.co/t5dVb0dio0

I had a blast presenting at @iOSKonf this week! I heard great things about this conference and I now can say that the praise was well-deserved! It was pretty scary to be on the lineup with so many accomplished engineers, but the vibe was good and everyone was easy to be around.

In the second talk of @iOSKonf we have @AlexOzun explaining how we can avoid illegal states in our apps. This is not only relevant for us developers but also for crafting excellent experiences for our users. Love the elegant implementations he shares.

@AlexOzun just delivered an incredible talk on making invalid states impossible in your app. Definitely one for the books! 🙌 #iOSKonf25

There are better ways to get back to the main stage after lunch? @AlexOzun 🧨🧨🧨

Good software design is about adding the necessary amount of indirection without compromising performance too much. Good performance optimization is about removing unnecessary indirection without compromising software design too much.

Heading into 2025 with 3 brand-new talks is kinda crazy, but I'm feeling good about this decision. I'm excited to share these talks with the community later this year! If you'll be at any of these conferences, drop me a message.

My 2025 #swift conference schedule, so far: 1. @swiftheroes_it (April 8-9): Controlling Side Effects with Swift. 2. @iOSKonf (May 13-15): Make invalid state impossible in your apps. 3. @swiftcraftuk (May 20-21): Swift Abstractions Demystified.

Caffeinated and ready to learn how to build fast and efficient apps from #Apple engineers at the new Dev Center in Battersea Power Plant.

If you're interested in Noncopyable types, type-level programming, and State Machines, check out the recoding of my talk from Swift Heroes 2024. I had a lot of fun researching the feasibility of Typestate programming in Swift, and I'm happy about how this presentation tuned out

The best VisionOS-related talk I've seen so far, well-presented and showcasing an actually meaningful use case (sign language recognition). Well done @monika_mateska @iosconfsg

Yes, they really flew me all the way from London to Singapore just so I could show a photo of an elephant to @iosconfsg audience.

I'm on Bluesky in case you want to connect https://t.co/Xzzjl1oJ00

Huge fan of @iosconfsg and it's a great honour to be on a speaker line-up. I'm bringing a new talk on managing side effects and building effect systems. There's been interesting developments in this area in mainstream functional programming, let's see how modern Swift keeps up.

Limited to integer values (for now?), but still open up some interesting possibilities for creatively exploiting the type system.

Wake up babe, Swift is getting dependent types! Looks like all the time I spent noodling with Idris wasn't a complete waste after all 🙃 What a time to be a Swift programmer! https://t.co/tKmwN9yEuI

This paper on reference counting claims that Swift programs spend avg 30% of their runtime on RC. Which is quite unbelievable. Is it real? Granted, it's from 2018, and Swift coding patterns shifted more to using value types and now borrowing, but still. https://t.co/bEX71eUn7C

Just had a random intrusive thought that Mono Lisa would be a fun name for monospaces font. So googled it, and sure enough, it already exists! https://t.co/E37QtQZlBf
