implement-plan

Canon TDD is a strict test-first methodology where every production change is preceded by a failing test. Applied to SwiftUI feature implementation, it manages the lifecycle from plan derivation and test list creation to final verification, ensuring architectural consistency and test coverage.

To implement SwiftUI features test-first, derive a plan, create an evolving test list, and write a failing test before any production code. This workflow automatically integrates domain-specific expertise for SwiftData and Swift Concurrency to ensure architectural compliance across feature modules.

Yes, the test-driven development workflow supports SwiftData and Swift Concurrency. It automatically leverages domain-specific specialist expertise to ensure architectural compliance across feature modules and data layers when implementing Popcorn SwiftUI features.

The best way to maintain test coverage and architectural consistency is enforcing a strict test-first Canon TDD workflow. This approach manages feature development from plan derivation to final verification, satisfying requirements for public API documentation and architectural consistency across data layers.

Strict test-first development requires a visible, evolving test list to bridge the gap between high-level project plans and granular code implementation. This list maintains a high-quality, verifiable codebase by ensuring every production change is preceded by a failing test.

You need to document public APIs during test-driven feature implementation as a final verification step. The strict test-first Canon TDD workflow explicitly satisfies requirements for public API documentation and architectural consistency across feature modules and data layers.
