What it is

SwiftFormat is a command-line tool and Xcode editor extension that reformats Swift code beyond simple whitespace adjustment—it can insert/remove implicit self, eliminate redundant parentheses, correct operator spacing, and enforce idiomatic Swift patterns. It's deployed as a standalone binary, Xcode extension, Swift Package Manager plugin, and Docker image to standardize code style across teams and CI/CD pipelines. Dual-architecture project: CommandLineTool/main.swift wraps a core formatting engine; EditorExtension/ contains the Xcode UI in EditorExtension/Application/Source/ (AppDelegate, RulesViewController, UserSelection) and extension hooks in EditorExtension/Extension/…

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/nicklockwood/SwiftFormat.git && cd SwiftFormat && swift build -c release. The CommandLineTool/main.swift is the entry point; binary output goes to .build/release/swiftformat. For Xcode exten…

Daily commands:

swift build -c release && .build/release/swiftformat --help (for CLI). For editor extension: open EditorExtension/Application.xcodeproj in Xcode, select SwiftFormatter target, press Run. For Docker: docker build -t swif…

Key cautions & unknowns

• Concentrated ownership — top contributor handles 71% of recent commits
• 1. macOS notarization (notarize.yml) requires valid signing credentials and AppleID secrets—local builds skip this but distributed binaries must be notarized. 2. Windows builds (windows_release.yml) use a separate…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
