swiftlang/swift has 2,131,342 source lines of code out of 3,073,988 total lines across 12,504 files, counted from the 0a93b4f984f4602abb4404e4333b481190b9d61e ref at commit 0a93b4f984f4 by the OctoCounts tokei engine on 2026-09-13. The report is cached by commit, tokei version, and analysis options, so recounting the same revision returns exactly these numbers.

OctoCounts produced this report by resolving swiftlang/swift to commit 0a93b4f984f4, downloading the repository source archive, and counting every source file with tokei, the open-source line counter written in Rust. The table below breaks the count down by programming language into files, total lines, code lines, comment lines, and blank lines, so the figures can be compared across languages and projects. Results are cached by commit, tokei version, and analysis options, so counting the same revision again reproduces exactly these numbers.
