610.0.1 binary frameworks for https://github.com/swiftlang/swift-syntax
Status 27/4/25: Rebuilt taking the above tag of the swift-syntax repo using Xcode 16.3 and seems to be working quite well using that Xcode. It can work with earlier versions particularly if you open the project in Xcode 16.3 first.
This is a Swift Package containing precompiled binary frameworks of the main modules of the swift-syntax project. It is intended this can be packaged up and used in place of the swit-syntax source repo by Swift Macro projects to avoid this problem people have experienced It operates by overriding the swift-syntax source repo pulled in by your macros by dragging it onto your project as you would to work on a Swift package as is documented here.
To use, build your project (and view any previews you would like to view), then clone this repo, renaming the InstantSyntax directory to swift-syntax and unpack the compressed archives using a script exactly as follows:
git clone https://github.com/johnno1962/InstantSyntax -b main --single-branch swift-syntax
./swift-syntax/601.0.1/unpack.sh
Now, drag this swift-syntax clone onto the top level of your project
that uses macros. This binary distribution should then take the place
of the swift-syntax source repo in the side bar in all macro packages.
If your project builds but you see errors in the source editor run the script ./fix_source_editor.sh supplying the plugin executable path the error mentions and the next time you edit the error should go away.
If you still experience problems involving "duplicate copy commands being generated" when you try to build, this is beacuse the repo's Package.swift seems to tickle some sort of bug in the build system related to binary frameworks and you won't be able to use the package with that version of Xcode.
These .xcframeworks were a bit involved to build. First, you need to use
an old Xcode 13 version of "swift package generate-xcodeproj" to generate
a swift-syntax.xcodeproj project file and add a build top level setting
BUILD_LIBRARY_FOR_DISTRIBUTION = YES. Then, you can generate and package
the binary frameworks using xcodebuild in the normal way. Where extra
security is imperitive (even though compiler plugins execute in a very
restrictive sandbox) there is a script package_syntax.sh in the repo
that allows you to rebuild your own fork of this repo directly from the
Apple sources which you can use instead.
