Bitrig brings “vibe coding” to iPhone — build native SwiftUI apps with AI

Bitrig is a new iPhone app — developed by a team of former Apple engineers involved with SwiftUI — that lets you create native SwiftUI apps directly on your iPhone using AI. The app runs a custom Swift interpreter on the device, enabling generated code to call into iOS frameworks and access hardware (camera, GPS, motion, etc.) without a Mac or Xcode.

Quick summary

• AI-driven “vibe coding”: describe or speak your idea and Bitrig generates runnable Swift & SwiftUI code on-device.
• Native features: generated apps can use MapKit, Photos, Notifications and device hardware.
• Edit & share: tweak the code, preview instantly, and share projects via AirDrop, Messages or export to Xcode/TestFlight.
• Built by ex-Apple engineers (including contributors to SwiftUI), aiming to democratize app creation on iPhone.

Why it matters

Bitrig demonstrates a shift toward powerful on-device AI tools that let people prototype and ship native apps without traditional desktop tooling. For developers it can speed iteration; for creators and entrepreneurs it lowers the barrier to building mobile apps.
