Why "The Composable Architecture" Matters for iOS App Development
summary
Introduces The Composable Architecture (swift-composable-architecture) for iOS app development and demonstrates concrete Swift code: a simple counter, two composed counters, and a counter with a 1s delayed increment plus a “number fact” web API. Shows reducer composition using scope, effects implemented as Combine publishers that map back to actions, dependency injection via an environment, and tests with TestStore and a test scheduler by swapping real effects for stubs to keep state changes deterministic and avoid a giant global reducer.
