Is 10x designer a thing?
To make this video, I made a mini After Effects native app with Bitrig that allows me to work with sequences, transitions all using the power of my Mac. It was really fun to build as I was thinking and making the video and examples!

You can now type, click, draw, and speak to Bitrig.
Use whichever interaction mode the situation calls for, and turn the idea in your head into a real app as quickly and faithfully as possible.
Jun 2
Bitrig now lets you select to edit elements in the App Preview.
Spend less time describing what's on the screen. Just point directly at the parts of your interface you want to change.

Sean has helped make iOS development accessible to an entire generation of developers.
I couldn’t be more excited to have him joining Bitrig as we carry that mission forward into the AI era of native iOS development.

I've joined @BitrigApp and I'm pumped to work with such an awesome team (which includes the co-creators of SwiftUI at Apple).
AI has changed how we build and I love what Bitrig is cooking up for this new era of native iOS dev with Swift & SwiftUI.

One cool thing about App Intents: Xcode extracts intent metadata at compile time, so Shortcuts, Siri, and Spotlight can discover and display your app’s actions before it’s ever been launched.
May 27
Bitrig can now build App Shortcuts and App Intents.
Make your app’s most important actions and content available in Shortcuts, Siri, and Spotlight.

One thing we learned building SwiftUI: make native technologies more accessible to designers, and they can do incredible things.

Fun Fact:
For this video I built a Mac app using @BitrigApp that let me create an animated carousel of watchOS examples.
I can control rotation, scale, blur etc, and use the arrow keys to move left and right.
It was easier to build it and record than learning a new tool!

Swift Playgrounds is genuinely impressive technology.
It’s disappointing it never evolved from a learning environment into a professional app development tool.
Now that we’re no longer at Apple, we’re building the version we always wanted 🙂

There are two kinds of people.
Coke people and Pepsi people. Coffee people and tea people. Morning people and night people. And, increasingly, Claude Code people and Codex people.
We’re building Bitrig for all of you 🙂

So excited to have Fede joining. He’s helping us make Bitrig even better for designers.
One thing we learned building SwiftUI: make native technologies more accessible to designers, and they can do incredible things. Fede has already built mind-blowing stuff with Bitrig.

There’s debate about whether you can vibe code a polished native app.
From what we see at Bitrig, yes. But it still takes skill, taste, and iteration.
You need to live with the app, TestFlight it, gather feedback, and refine.
That’s how Stu built Prolost Watches prolost.com/blog/prolostwatc…
