SwiftSyntax is a set of Swift bindings for the libSyntax library. It allows Swift tools to parse, inspect, generate, and transform Swift source code.

Its API is designed for performance-critical applications. It uses value types almost exclusively and aims to avoid existential conversions where possible.

Note: SwiftSyntax is still in development, and the API is not guaranteed to be stable. It's subject to change without warning.

Declare SwiftPM dependency with release tag

Add this repository to the Package.swift manifest of your project:

// swift-tools-version:5.3
import PackageDescription

let package = Package(
  name: "MyTool",
  dependencies: [
    .package(name: "SwiftSyntax", url: "https://github.com/apple/swift-syntax.git", .exact("<#Specify Release tag#>")),
  targets: [
    .target(name: "MyTool", dependencies: ["SwiftSyntax"]),

Replace <#Specify Release tag#> by the version of SwiftSyntax that you want to use (see the following table for mapping details).

Xcode Release Swift Release Tag SwiftSyntax Release Tag
Xcode 13.3 swift-5.6-RELEASE 0.50600.1
Xcode 13.0 swift-5.5-RELEASE 0.50500.0
Xcode 12.5 swift-5.4-RELEASE 0.50400.0
Xcode 12.0 swift-5.3-RELEASE 0.50300.0
Xcode 11.4 swift-5.2-RELEASE 0.50200.0

Then, import SwiftSyntax in your Swift code.
