Bitrig Adds iPhone Duo Support with Interactive 3D Simulator for AI Development
AI coding platform Bitrig has updated its environment to support building and testing apps for the foldable iPhone Duo following Apple's Xcode 27.1 Beta 1 release. The update introduces an interactive 3D simulator that lets developers prototype dual-screen SwiftUI layouts and test real-time hinge interactions. This tool simplifies early adoption of foldable iOS form factors by allowing developers to simulate dual-screen device postures without requiring physical hardware. It enables AI-assisted platforms to bridge the gap between high-level prompt-based app generation and complex new hardware features like hinge state handling. The 3D simulator allows developers to fold, tilt, and rotate the virtual device while tracking real-time hinge data using SwiftUI modifiers like `onHingeChange` and layout primitives like `ArrangementView`. Bitrig also features multi-version Xcode management, enabling developers to test against beta SDKs while keeping stable build workflows intact.
## BACKGROUND
Bitrig is an AI-powered app builder that converts natural language prompts into native Swift and SwiftUI code for Apple platforms, supporting a prompt-driven workflow often referred to as 'vibe coding'. SwiftUI is Apple's declarative UI framework, which recently added APIs to support dynamic adaptive layouts across distinct screen orientations and fold states on dual-screen devices.
