About This Tool

Tool identifies code quality issues by leveraging clang's static analysis on Xcode projects, scanning source files and build metadata to surface diagnostics with precise locations. It supports C, C++, Objective-C, and Swift, and integrates with compile_commands.json or Xcode build data to reflect the real build configuration. The approach is language-aware and architecture-aware, producing actionable diagnostics rather than generic warnings.
The core value is early defect detection that reduces debugging time, prevents crashes, and improves maintainability across teams. It exports structured results such as per-diagnostic details, summary counts, and SARIF for downstream tooling, enabling automation in CI pipelines and code review workflows.
Core features include: multi-target analysis, incremental operation with caching, suppression and whitelisting, and straightforward export to SARIF or logs. The tool is designed to fit existing Xcode workflows without requiring UI changes, and it surfaces precise file/line locations for rapid triage.

Frequently Asked Questions

Find Quick Answers

What languages are supported?

The tool analyzes C, C++, Objective-C, and Swift code using the clang static analyzer. It accommodates mixed-language Xcode projects by resolving per-file language contexts and correlating diagnostics to source locations across targets.

Can results be used in CI?

Yes. Diagnostics can be exported as SARIF for integration with CI scanners and code review systems. You can configure the workflow to fail the build on high-severity issues, enabling gatekeeping before merges.

What inputs are required?

Essential inputs include project_path, target_name, build_config, and language. Optional inputs include compile_commands_path and extra_args to tailor the analysis depth and rules for specific projects.

What outputs are produced?

The tool emits a diagnostics array with file, line, column, severity, and message, plus a summary of counts. Optional outputs include a SARIF payload and log files suitable for ingestion by CI and code-review pipelines.
