SwiftSyntax is a set of Swift libraries for parsing, inspecting, generating, and transforming Swift source code.
Note: SwiftSyntax is still in development, and its API is not guaranteed to be stable. It is subject to change without warning.
The mainline branch of SwiftSyntax tracks the latest developments. It is not
an official release, and is subject to rapid changes in APIs and behaviors. To
use it, add this repository to the Package.swift
manifest of your project:
// swift-tools-version:5.7
import PackageDescription
let package = Package(
name: "MyTool",
dependencies: [
.package(url: "https://github.com/apple/swift-syntax.git", branch: "main"),
],
targets: [
.target(name: "MyTool", dependencies: [
.product(name: "SwiftSyntax", package: "swift-syntax"),
]),
]
)
Mainline SwiftSyntax also includes
SwiftParser
for natively parsing source codeSwiftOperators
for folding SwiftSyntax trees containing operatorsSwiftSyntaxBuilder
for generating Swift code with a result builder-style interface
Releases of SwiftSyntax are aligned with corresponding language
and tooling releases and are stable. To use them,
add this repository to the Package.swift
manifest of your project:
// swift-tools-version:5.7
import PackageDescription
let package = Package(
name: "MyTool",
dependencies: [
.package(url: "https://github.com/apple/swift-syntax.git", exact: "<#Specify Release tag#>"),
],
targets: [
.target(name: "MyTool", dependencies: [
.product(name: "SwiftSyntax", package: "swift-syntax"),
]),
]
)
Replace <#Specify Release tag#>
by the version of SwiftSyntax that you want to use (see the following table for mapping details).
