PBXProj Validator Online

This tool analyzes PBXProj content to verify correctness of the Xcode project structure. It parses the file’s sections, cross-references UUIDs, and validates targets, build configurations, file references, groups, and project metadata. Conceptually it treats the PBXProj as a graph of objects and relations, and checks for orphaned references, missing files, duplicates, and inconsistent configurations. The result is a detailed report of errors and warnings with location hints to guide developers. Beneficiaries include iOS/macOS team members, build engineers, and CI pipelines who maintain large or multi-target projects. Unique value lies in deterministic, line-accurate feedback without requiring a full build, enabling faster cleanup, safer merges, and earlier detection of structural regressions. Core features include syntax validation, cross-reference checks, UUID consistency, duplicate detection, missing file references, and basic lint rules for common misconfigurations. Use cases include pre-commit checks, CI validates on pull requests, and on-demand project audits for refactors.
