The new platform picker we just added is the first part of Bitrig we’ve designed in Bitrig!

Digging into the Claude Agent SDK and wiring it into Bitrig was a lot of fun! Really excited about what this unlocks for users, and there's so much more we can do with it.

I just posted the final blog post about how the Bitrig Swift Interpreter works, check out the whole series if you're curious!

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. Check out the full video! #BuildInPublic youtube.com/watch?v=rz_7cu…

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 My viral video on building an iOS app with AI is obsolete.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 🧙

Bitrig just got a makeover! The UI now reflects the iOS 26 Liquid Glass design language, and it's ready to make your apps look just as great. It also incorporates the new Foundation Models, brings support for Sign in with Apple, and fixes a whole bunch of bugs. Check it out now, and don't forget to tell us what you make! apps.apple.com/us/app/bitrig/… #Bitrig #Swift #SwiftUI #BuildInPublic

Bitrig is making native iOS app development as easy as a quick chat. And today we’re revealing more about how we did it. Check out Part 2 of our series digging into how Bitrig works. #Swift #SwiftUI #BuildInPublic #Bitrig bitrig.app/blog/interpret…

I wrote a blog post to answer some questions about how our interpreter works - let me know if you have want to know more!

Today we’re happy to announce Bitrig for Mac. The Mac app is still in beta, but starting now we’re offering early access to Bitrig subscribers. If you hold a subscription, watch your email for your exclusive invitation to try it out.

@EastlondonDev @BitrigApp We don't support that yet, but I think that'd be a great addition!

@BitrigApp I’ve played with it a little bit - is there a way that I can sync the code with a GitHub repo?

Today we’re excited to launch Bitrig. Bitrig builds native Swift apps just by chatting with AI. In minutes, and with no code required, you can create an app and deploy it directly to TestFlight. youtu.be/e-DqSVEI50w #Swift #SwiftUI #BuildInPublic

Today we’re launching TestFlight integration in bitrig. Now you can vibe code, test, and deploy Swift apps. All from your iPhone. If you want to give bitrig a try, sign up here → bitrig.app

After selling his Apple Watch, Federico missed the Mindfulness app. So he used bitrig to build a better one, which plays haptics just the way he wanted. What will you build?

Thrilled to share that our former SwiftUI colleague and Apple Design Award winner @tdonnelly has joined the @BitrigApp team! Thanks to Tim, the welcome screen has gotten a much-needed facelift. Isn’t it mesmerizing?

Dante’s smart scale broke and logging his weight manually got old fast. So he built an app that made it as easy as replying to a daily reminder. What will you build?

Just accepted the first wave of testers off the waitlist into our TestFlight. If you didn't get in yet, don't worry! We'll be accepting more testers in the coming days. If you haven't already, join the waitlist here → bitrig.app

@camsoft2000 @rudrank Bitrig: bitrig.app

@rudrank @jacobx What's the app?

I found this so cool app by @jacobx that makes an app in an app! I got it to do the HealthKit integration as well to prototype an app to prepare for a marathon!!

There's a great new library for parsing command-line arguments in Swift! It provides type safety, automatically generates help and useful error messages, supports subcommands, and is really fun to use. Take a look! swift.org/blog/argument-…

It’s great seeing what everyone is building with SwiftUI! If you’re excited about SwiftUI, come join our incredible team and work on improving SwiftUI itself: jobs.apple.com/en-us/details/…
