A preview of ComposableArchitecture 2.0: a fundamental redesign featuring the @Feature macro, implicit store access for async work, lifecycle hooks, new communication patterns, and deep integration with DebugSnapshots for testing.

PointFree's platform is a resource for Swift developers, offering insights into functional programming techniques, Swift language features, and iOS app development with Swift. Through articles, tutorials, and code samples, PointFree offers insights into functional programming patterns, monads, and composable architecture in Swift. Readers can learn about building robust and testable iOS applications, leveraging functional programming paradigms, and embracing type safety to write expressive and maintainable Swift code.

Point-Free Pointers

ComposableArchitecture 2.0 is a fundamental redesign of the popular Swift architecture library. Key changes include a new @Feature macro replacing reducer terminology, implicit store access for async work via store.addTask and store.modify, simplified SwiftUI bindings without boilerplate, lifecycle hooks (onMount/onDismount), and new inter-feature communication patterns including preferences, events, triggers, and delegate closures. Testing is improved through DebugSnapshots integration, better async determinism, and a new TestStoreActor for parallel test execution. Migration is eased via three modules: ComposableArchitecture2 (new API), ComposableArchitecture1 (1.x compatibility shim), and ComposableArchitecture (umbrella re-export). The release is currently in beta preview under the new Point-Free Max membership tier.
