TCA Action Boundaries

Read Original

This technical article analyzes a problem in The Composable Architecture (TCA) for Swift: the lack of boundaries for Action enums. The author, drawing from experience building large apps like Arc, explains how parent reducers observing child feature actions can lead to tight coupling, anti-patterns, and hard-to-debug issues, as Swift enums provide no access control. It proposes the need for better encapsulation.
