# macOS SwiftPM Runner ## Quick Start Use this skill when `Package.swift` is the primary entrypoint or when SwiftPM is the fastest path to a reproducible result. ## Workflow 1. Inspect the package. - Read `Package.swift`. - Identify executable, library, and test products. 2. Build with SwiftPM. - Use `swift build` by default. - Use release mode only when the user explicitly needs it. 3. Run the right product. - Use `swift run <product>` when an executable exists. - If multiple executables exist, explain the default choice. 4. Test narrowly. - Use `swift test`. - Apply filters when a specific test target or case is known. 5. Summarize failures. - Module/import resolution - Package graph or dependency issue - Linker failure - Runtime failure - Test regression ## Guardrails - Prefer SwiftPM over Xcode when both exist and the package path is clearly simpler. - Do not assume an app bundle exists in a pure package workflow. - Explain when the package is library-only and therefore not directly runnable. ## Output Expectations Provide: - the package products you found - the command you ran - whether build, run, or test succeeded - the top blocker if not
