Latest Trunk Toolchain Missing `lib_SwiftSyntaxMacros.dylib` for arm64?

Development Compiler

I'm trying to use the latest Swift Trunk Development toolchain builds (from December 4th and 5th), but it seems like lib_SwiftSyntaxMacros.dylib was only built for x86 and not arm64. This causes every swift invocation to fail immediately as shown below:

> export PATH=/Library/Developer/Toolchains/swift-DEVELOPMENT-SNAPSHOT-2022-12-05-a.xctoolchain/usr/bin:"${PATH}"
> swift --version

I am on macOS Version 13.0.1 (22A400) on an M1 Pro MacBook Pro.

Am I using it wrong, or will this be fixed again with the next toolchain builds? Is there a simple fix I could apply in the meantime?

Thanks for your help!

Can confirm this, I am having the same issue.

@Douglas_Gregor sorry to tag you, but are you aware of this?

I am, and I'm looking into it today. I suspect a CMake bug that's tripped us up before, and if it's that---the workaround is simple.

Update: this took longer than I'd hoped, but the fix is finally merged and the toolchain built in the PR has the right content in it. Thanks for your patience, everyone.
