periphery

historique

Historique du projet et usages

Periphery is an archived open-source command-line analyzer that identifies unused declarations in Swift projects by combining build index data with source analysis.

Historique du projet

Periphery was developed as an open-source Swift static-analysis tool centered on Xcode and Swift Package Manager projects. Its changelog identifies version 1.3.0 in February 2019 as the first open-source release.

The scanner evolved from syntax-oriented analysis toward index-store-based whole-project analysis, adding configuration persistence, CI reuse of existing builds, Bazel support, and handling for newer Swift and Xcode constructs.

The last documented release before archival was in the 3.8 series in July 2026. The official GitHub repository was archived the following month.

Historique d'adoption

Periphery was adopted in iOS, macOS, and Swift package maintenance as a focused way to detect declarations that compile but are no longer reachable. Its support for Xcode, Swift Package Manager, Bazel, local command-line use, and continuous integration made it practical across several Swift build workflows.

Official Homebrew support was added in 2019. In December 2024 the project moved from its custom Homebrew tap into Homebrew's main formula collection. The upstream repository was archived and made read-only on 12 August 2026.

Modes d'utilisation

Run `periphery scan --setup` for guided initial configuration, then persist established options in `.periphery.yml` at the project root and use `periphery scan` for repeatable analysis.

Periphery builds projects to generate an index store, or CI can reuse a previous build with `--skip-build` and `--index-store-path`. All relevant targets must be built to reduce false positives; standalone frameworks may require `--retain-public`.

Pourquoi les passionnés de paquets s'y intéressent

Periphery fills a narrow gap between compiler diagnostics and general linting: it builds or consumes an index store, constructs a declaration-reference graph, and searches that graph for unused code across project targets.

Its archived status is operationally important to package users. Existing releases remain useful, but adopters should account for the absence of ongoing upstream maintenance when new Swift, Xcode, or project-file formats appear.
