Could you build this?

Partial A macOS tiling window manager requires native Swift/Objective-C development using low-level Accessibility APIs and window server quirks that AI assistants frequently hallucinate or struggle to debug.

What it would actually take: Built with Swift using macOS Accessibility APIs (AXUIElement) and event taps (CGEventTap) without crashing or lagging the OS. The hard part is managing complex multi-display layouts, app-specific accessibility quirks, and handling macOS spaces without private APIs. This demands an experienced macOS systems developer familiar with Cocoa and Core Graphics.
