dead-code-scanner

To find unused Swift code after refactoring, you need static analysis that tracks symbol declarations and usages across your entire codebase. This dead code scanner identifies orphaned functions, types, and properties with no references, generating a markdown report with per-symbol confidence and remediation suggestions.

Detecting unused functions and types in a Swift codebase requires reference tracking that maps every declaration to its usages. A full codebase scan analyzes these symbols, respects allowlists and inline annotations to prevent false positives, and outputs structured findings for review.

You can prevent certain Swift symbols from being flagged as dead code by using allowlists and inline annotations. The scanner respects these exclusions during reference tracking, ensuring symbols exposed via reflection or external interfaces are not mistakenly reported as unused.

Dead code detection with Swift static analysis works by parsing symbol declarations and cross-referencing them against usages throughout the codebase. It calculates per-symbol confidence scores for unused declarations and generates a markdown report under .agents/research with remediation suggestions.

Dead code scanning may report false positives for public APIs because static analysis cannot detect external references outside the codebase. You can suppress these false positives by adding affected symbols to an allowlist or annotating them inline to exclude them from unused code detection.
