xcconfig extractor

xcconfig extractor is a developer-focused tool that parses Apple XCConfig files to reveal build settings, environment overrides, and conditional values. It targets iOS and macOS teams, CI engineers, and project maintainers who need a fast, auditable view of configuration state. By converting raw key-value lines into a structured report, it eliminates manual search, reduces misconfigurations, and accelerates debugging when build settings diverge between schemes or targets.
Conceptually, the tool reads XCConfig text, trims comments, resolves includes, and merges base values with conditional blocks. It records the origin of each value (file, line) and can show the effective value for a given configuration context. Optional features highlight duplicates, report unused keys, and flag common mistakes such as quoted vs unquoted values or missing values. Outputs are structured and machine-friendly to support automation.
Core outputs include a JSON-like map of keys to values, source references, and optional metadata. Use cases include pre-merge audits, release tagging, and environment-specific builds. The extractor also supports batch processing of multiple XCConfig files, preserving hierarchical relationships and providing a consolidated view for large projects. This simplifies onboarding and reduces time-to-build for new contributors.
Because it is domain-focused, it delivers precise insights without UI noise and integrates into existing workflows via export formats and scripting interfaces. It is designed to be deterministic, repeatable, and suitable for parameter-driven pipelines.
