How it got here

2015–2021 · Modernization and tooling standardization

This period focused on modernizing the codebase by migrating to Swift 6.3 and replacing the legacy Xcode project structure with standardized configuration files and build systems. The team also enhanced the CLI experience by adding shell completion scripts and refactoring the application's entry point.

2024–2025 · Swift 6.2 migration and CLI modernization

This period focused on modernizing the codebase by migrating to Swift 6.2 and adopting async/await concurrency patterns across the CLI and model layers. The work introduced new command-line options for app identification and update accuracy, while also standardizing build tooling and expanding test coverage for the new model structures.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 3 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit c29d020431 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
