Hyperdeck
summary
Hyperdeck is a Markdown-based presentation app for iPad and Mac that actually parses slides into a tree and renders them live; it uses Rust Aho-Corasick concurrent parser to split and parse ~150 slides, returns UTF‑8 ranges converted to Swift/ObjC, and applies a fast FMV hash for cache validation. The codebase is ~34k Swift + 11k Rust with 1,600 commits, typing stays under <10 ms latency, iOS is stable but macOS via Catalyst is fragile and requires many workarounds.
