SwiftUI & Combine
summary
Covers the concrete mechanics of using Combine with SwiftUI and UIKit: wiring @Published properties and subscribing to their dollar bindings, transforming values with map, merging streams with combineLatest, and handling async JSON decoding with flatMap plus error fallback. Demonstrations include a clicker, a rock‑paper‑scissors pipeline, and UIKit target‑action wiring. Claims that Combine operators are the practical equivalents of array map/filter and discusses production readiness and integration tradeoffs.
