Migrating outdated TCA code involves applying the @Reducer macro, @ObservableState, and struct-of-closures dependencies to replace deprecated patterns. This skill guides you through validating pre-1.7 migrations and modernizing large codebases for clean, testable SwiftUI reducers.

Implement sheet and push navigation in TCA by using tree-based @Presents and stack-based StackState. This approach enables direct store access and modern navigation structures, allowing you to manage complex routing and view presentation cleanly within your SwiftUI features.

AI tools generate outdated TCA code because they lack the latest 1.7+ enterprise patterns. This skill encodes modern conventions like @Reducer, @ObservableState, and @DependencyClient to ensure generated code satisfies current compiler requirements and architectural standards.

Yes, you can manage dependencies and parent communication using @DependencyClient and delegate actions. This pattern decouples child features from their parents, allowing scalable decomposition with Scope and ifLet while maintaining comprehensive TestStore testability.

The best way to structure TestStore tests is by validating state changes and delegate actions exhaustively. This skill provides patterns to build TestStore tests that satisfy modern @Reducer macro requirements and verify dependency interactions and navigation flows.

You need StackState for stack-based push navigation like drill-in lists, and @Presents for tree-based modal sheet presentation. This skill helps you implement both direct store access patterns to manage complex navigation routes within scalable SwiftUI architectures.
