Bitrig<\/a> (tweet<\/a>):<\/p>\n

Turn your ideas into apps in seconds, just by chatting with AI. No programming languages to learn, no complex tools to set up.<\/p>

[…]<\/p>

Bitrig speaks Swift and SwiftUI. Your apps are built with the same technologies Apple uses, and can tap into powerful features like your health data, notifications, and Home Screen widgets.<\/p>

[…]<\/p>

It’s always in your pocket, so you can experiment whenever and wherever inspiration strikes.<\/p><\/blockquote>\n\n

The fathers of SwiftUI left Apple and are working on a new project together to create native apps in with phone just through prompting! Super impressive technology!<\/p>\n<\/blockquote>\n\n

Jacob Xiao and Kyle Macomber presented SwiftUI at WWDC 2019<\/a>.<\/p>\n\n

Bitrig builds Swift and SwiftUI apps, which run on your iPhone using a custom Swift interpreter.<\/p>\n

Your apps call directly into the native SDK, so they can do things like access health data, post user notifications, and play haptics.<\/p>\n

We’re ingesting the iOS SDK into bitrig piece-by-piece. Tell us what you’re building, we’ll prioritize what you need!<\/p>\n<\/blockquote>\n\n

It’s a custom interpreter for swift, written in swift. Whenever it encounters library calls, the interpreter makes native calls.<\/p>

While shipping, we ship the swift code that runs natively and compiled using the actual compiler.<\/p><\/blockquote>\n\n

This sounds great, though I don’t understand how it’s compatible with the App Review Guidelines.<\/p>\n\n

Today we’re launching TestFlight integration in bitrig.<\/p>\n

Now you can vibe code, test, and deploy Swift apps. All from your iPhone.<\/p>\n<\/blockquote>\n\n

Seeing Bitrig hot-reloading code changes makes me wonder why hasn’t Apple brought us something like that in years instead of booting a simulator within Xcode and labelling it as previews.<\/p><\/blockquote>\n\n

Interesting that the payments link goes to Stripe instead of using in-app purchases, and that you can use it to distribute native code outside of the App Store.<\/p>\n<\/blockquote>\n\n
