Bitrig has rolled out support for developing and testing applications for the new iPhone Duo. This follows Apple's release of Xcode 27.1 beta 1, which introduced the necessary tools for iPhone Duo app creation. Bitrig's update provides developers with the ability to build and test apps specifically designed for the foldable device.
A key feature of Bitrig's update is an interactive 3D simulator for the iPhone Duo. This simulator allows developers to virtually fold, tilt, rotate, and position the device to observe how their applications respond to different physical configurations. This functionality is crucial for ensuring apps adapt correctly to the iPhone Duo's unique form factors, such as laptop mode, tent mode, and various open or closed states.
Bitrig, which started as a simple vibe-coding app, has expanded its platform to include a Mac application that provides access to the full Xcode toolchain, an integrated iPhone simulator, and on-device testing. The platform also supports exporting projects to Xcode and distributing apps via TestFlight and the App Store. The new iPhone Duo support extends these capabilities to the latest device.
The update enables developers to test app responses to hinge movements using `onHingeChange` and to build hands-free experiences with `ArrangementView` for split-screen layouts. It also supports utilizing both displays simultaneously, for example, by adding a `CameraCaptureAccessory` to the outer display. Bitrig also facilitates managing multiple Xcode versions, allowing developers to work with the iPhone Duo beta while maintaining compatibility with Xcode 27 for existing projects.
