Could you build this?
No Rendering SwiftUI headless without the iOS Simulator by extracting accessibility trees and hot-reloading in ~2 seconds requires low-level Swift compiler and private Apple runtime hacking.
What it would actually take: This requires reverse engineering Apple's closed-source SwiftUI layout engine and AttributeGraph private runtime on macOS, or compiling SwiftUI views natively against macOS runtimes while injecting custom accessibility accessibility-tree builders. It involves dynamic Mach-O hooking, Swift runtime metadata reflection, and custom JIT/dlopen hot-reloading mechanisms. Deep systems programming and internals knowledge of Apple's private frameworks are essential.
