swift-format is the official Swift source code formatter, providing formatting technology used by SourceKit-LSP. It can be used as a command line tool or linked into other applications as a Swift Package Manager dependency via its API.

Use cases

• format swift source code
• enforce consistent swift style across a codebase
• integrate swift formatting into an editor or lsp
• run swift code style checks in ci
• build custom swift code transformation tools

When to choose

• you write Swift and want automatic, consistent formatting
• you need formatter integration with SourceKit-LSP or Xcode tooling
• you want to build tooling on top of a Swift syntax formatter API

When to avoid

• you need a formatter for languages other than Swift
• you require a fully agreed-upon official Swift style guide, which does not yet exist
• you are on Swift 5.7 or earlier and cannot match toolchain versions
