A set of Swift libraries for parsing, inspecting, generating, and transforming Swift source code via a source-accurate syntax tree (SwiftSyntax). It is the backbone of Swift's macro system, letting macros generate SwiftSyntax trees inserted into source files.
Use cases
- parse Swift source code into a syntax tree
- build Swift macros
- generate Swift source code programmatically
- write linters or refactoring tools for Swift
- transform or rewrite Swift source files
- analyze Swift AST for tooling
When to choose
- building Swift macros or compiler-adjacent tooling
- writing code generators, linters, or formatters for Swift
- you need a source-accurate, lossless representation of Swift code
When to avoid
- parsing languages other than Swift
- you only need lightweight regex-based text manipulation of Swift files
- you need a stable API surface across major versions without migration effort
