Grant Hinkson Built 2 Custom Bridges to Bring CONNECTOME to Apple Vision Pro

Summary
CONNECTOME is now available on Apple Vision Pro, but Grant Hinkson said the port only shipped after he built two custom native bridges and post-build patchers around Unity.
Unity’s default visionOS path, PolySpatial, could not run the Shapes library that drives the app’s visuals, pushing Hinkson to switch rendering to Metal to keep custom shaders working.
That fix broke Apple Vision Pro’s eye-hover behavior because Unity still lacks support for Apple’s 2025 Metal eye-tracking API, so Hinkson wrote compositor-level code to inject gaze data frame by frame.
SwiftUI color controls for the app’s room-by-room hues were also unavailable through Unity, requiring a second bridge and another patcher to preserve changes after each build export.
Hinkson’s account highlights a broader XR bottleneck: new headsets may offer APIs, but without full engine support developers still spend time building private workarounds instead of shipping apps faster.
