Elevated Swift
summary
Swift code builds a working elevator simulator that implements the Knuth “keep going in your direction” policy, models hall vs car calls, runs an async event loop with a 60 Hz tick, and visualizes it in SwiftUI. Adding a fixed capacity = 5 shows single-elevator up‑peak failure; splitting logic into an multi-elevator dispatcher moves hall calls to the dispatcher and car calls into each elevator, and a two‑elevator simulation handles morning up‑peak while the single elevator cannot.
