Matt is one of the most thoughtful people I’ve ever worked with—from engineering to product to leadership. It’s a privilege to work with him again on @BitrigApp.

Excited to share that I've joined @BitrigApp! I love helping people learn to code. As a co-creator of SwiftUI, I also love building native apps for Apple's platforms. At Bitrig, we're developing new tools for making native app development more accessible and fun for everyone. I first got hooked on coding as a kid, making games on my TI-83 calculator. It felt magical to build apps with just the computer in my pocket. Using Bitrig to build native apps right on my phone rekindles that same playfulness, but with so much more versatility, and it's only just the beginning 🙂 I'm also joining an incredibly talented team, including some of the same people I worked with on SwiftUI. And we're hiring! Check out our jobs page to learn more.

Curious how Bitrig runs native Swift on your iPhone without compiling in Xcode?
Intern with us and learn alongside some of the smartest folks I've ever worked with like @jacobx and @tdonnelly.
The interview process is simple. No live coding. No LeetCode questions.

*Cue epic music*
The trilogy concludes.
In the final chapter of the Bitrig Swift Interpreter series, we reveal how complex expressions are evaluated at runtime and how they connect to real system frameworks. #BuildInPublic

We gave @superbetsy the power of Apple’s on-device Foundation Models… and she used it to build an app that translates GenZ slang for millennials, but is wrong 75% of the time and super duper confident about it.

Bitrig tech is really something (check their blog bitrig.app/blog/swift-int…). I'm super happy to be part of the experience of building apps by chatting with AI

I'm thrilled to share that @_julianschiavo is joining the @BitrigApp team!
It was a privilege to work with Julian on SwiftUI at Apple. He brings conviction and energy to everything he does. I can’t wait to see what we’ll accomplish together 🙂

This is the most insane leap in software creation I've ever seen...
My viral video on building an iOS app with AI is obsolete. I just built a fully native iOS app ON MY PHONE just by chatting. NO Mac. NO Xcode.
What @kylemacomber @jacobx @tdonnelly have built feels like actual magic... ✨ You guys are wizards 🧙
