Ants in My Chans
summary
Compares Clojure primitives (atoms, refs, STM, core.async channels) to iOS patterns (GCD/Dispatch queues and NSOperation), shows how message-passing via channels maps to queues and avoids shared-state races, and demonstrates an ants simulation re‑written with core.async channels and Swift that runs and coordinates many agents. Gives concrete tradeoffs: atoms/ref snapshots are fast for isolated state, STM handles coordinated multi-var updates, channels simplify composable async pipelines; shows long‑running work offloaded to threads with promise‑style callbacks.
