Overview

The SwiftParser framework implements a parser that accepts Swift source text as input and produces a SwiftSyntax syntax tree.

Quickstart

The easiest way to parse Swift source code is to call the Parser.parse method, providing it with a string containing the source code:

import SwiftParser
#if compiler(>=6)
internal import SwiftSyntax
#else
import SwiftSyntax
#endif

let sourceText =
"""
func greeting(name: String) {
  print("Hello, \(name)!")
}
"""

// Parse the source code in sourceText into a syntax tree
let sourceFile: SourceFileSyntax = Parser.parse(source: sourceText)

// The "description" of the source tree is the source-accurate view of what was parsed.
assert(sourceFile.description == sourceText)

// Visualize the complete syntax tree.
dump(sourceFile)
