Swiftpack.co - Package - joehinkle11/SwiftSyntaxStubExporter


SwiftSyntaxStubExporter provides all SwiftSyntaxStubs structs (found at https://github.com/joehinkle11/SwiftSyntaxStubs) the ability to be exported the JSON. This export ability is put in this separate repo to allow the App Maker App Clip to use the smallest possible version of the Swift Syntax Stubs.


Don't work directly on the .swift files, but instead work on SwiftSyntaxStubs.swift.gyb and run build-script.py to produce all the Swift.

  • SwiftSyntaxStubExporter relies on a modified version of Apple's GYB (GYB2) which allows a simple GYB file to produce multiple Swift files.
  • The default branch is main, not master
