Swift Code Formatter

The formatter analyzes Swift source to apply a consistent code style, including 4-space indentation, spaces around operators, and braces placement. It preserves comments and pragmas while reflowing lines to respect a maximum line length. It operates as a non-destructive formatting pass, leaving semantics intact and only adjusting whitespace.
It tokenizes input into Swift constructs and uses a lightweight AST-guided model to decide where to insert newlines, how to align parameters, and how to wrap long declarations. It handles let/var, type annotations, function and closure signatures, generics, enums, and control-flow blocks, ensuring readable, uniform formatting across files. It also preserves trailing comments, respects nested generics, and avoids moving code into semantically different regions during formatting.
This tool benefits teams seeking stable style, learners building good habits, and code reviewers who need predictable diffs. Its unique value is deterministic formatting aligned with Swift conventions, straightforward integration into CI pipelines, and a low-risk approach that avoids refactoring or semantic changes.
Use cases include preparing pull requests, standardizing legacy code, and enforcing a project-wide style guide. When adopted, teams experience faster reviews, fewer formatting debates, and higher code quality with consistent appearance regardless of individual contributors.
