v602.0.0
Apache-2.0
Command-line code formatter for Swift source code that powers SourceKit-LSP.
Why you might care
Provides consistent, automated formatting for Swift projects via CLI or as a Swift Package Manager dependency. Official tool from the Swift project; integrates with SourceKit-LSP for IDE support. Decoupled from Swift toolchain version as of 5.8, allowing broader compatibility.

"github_readme_excerpt": "# swift-format\n\n`swift-format` provides the formatting technology for\n[SourceKit-LSP](https://github.com/swiftlang/sourcekit-lsp) and the building\nblocks for doing code formatting transformations.\n\nThis package can be used as a [command line tool](#command-line-usage)\nor linked into other applications as a Swift Package Manager dependency and\ninvoked via an [API](#api-usage).\n\n\u003e NOTE: No default Swift code style guidelines have yet been proposed. The\n\u003e style that is currently applied by `swift-format` is just one possibility,\n\u003e and the code is provided so that it can be tested on real-world code and\n\u003e experiments can be made by modifying it.\n\n## Matching swift-format to Your Swift Version\n\n### Swift 5.8 and later\n\nAs of Swift 5.8, swift-format depends on the version of\n[SwiftSyntax](https://github.com/swiftlang/swift-syntax) whose parser has been\nrewritten in Swift and no longer has dependencies on libraries in the\nSwift toolchain.\n\nThis change allows `swift-format` to be built, developed, and run using\nany version of Swift that can compile it, decoupling it from the version\nthat supported a particular syntax. However, earlier versions of swift-format\nwill still not be able to recognize new syntax added in later versions of the\nlanguage and parser.\n\nNote also that the version numbering scheme has changed to match\nSwiftSyntax; the 5.8 release of swift-format is `508.0.0`, not `0.50800.0`.\n\n### Swift 5.7 and earlier\n\n`swift-format` versions 0.50700.0 and earlier depend on versions of\n[SwiftSyntax](https://github.com/swiftlang/swift-syntax) that used a standalone\nparsing library distributed as part of the Swift toolchain. When using these\nversions, you should check out and build `swift-format` from the release\ntag or branch that is compatible with the version of Swift you are using.\n\nThe major and minor version components of `swift-format` and SwiftSyntax must\nbe the same\u2014this is expressed in the `SwiftSyntax` dependency in\n[Package.swift](Package.swift)\u2014and those vers",
