Swift Coding AgentsPreview
In Swift repos on public GitHub, 168K PRs carried an agent mark between 2026-10 window start and end, which is 42.6% of all Swift PRs. Claude Code does the most of it.
Coverage: tracks Claude Code, Codex, Copilot agent, Cursor, Devin, and Jules. Codex is measured through hosted task metadata, checked against sampled PRs. Gemini CLI and other terminal agents work through the developer's own identity, leaving nothing public we can detect yet, so they cannot be measured here. We are expanding coverage. Methodology
