Katana is a Swift framework for structuring iOS app business logic in a Redux-inspired, unidirectional data flow, where a single serializable state is updated only via dispatched StateUpdaters. It was used in production by Bending Spoons but the team has since migrated to The Composable Architecture.
Use cases
- manage ios app state with redux pattern
- unidirectional data flow in swift
- testable business logic for ios apps
- centralized app state container in swift
- predictable state updates in mobile apps
When to choose
- building a small or medium-sized ios app that fits a redux-style architecture
- you want a single serializable app state with ordered, testable updates
- you prefer a lightweight swift-native alternative to redux patterns
When to avoid
- starting a new large ios project needing modular architecture (authors recommend The Composable Architecture)
- you need a framework under active development
- your app targets platforms other than ios
