Still running into this on the newest toolchain 2023-08-03 |
|
I was able to reproduce this issue on the nightly Swift release 2023-08-12 Running eg. a modified main.swift import KeyPathIterable
@KeyPathIterable
struct Thing {
var foo: Double
var bar: Double
}
var thing = Thing(foo: 1, bar: 20)
for keyPath in Thing.keyPaths {
debugPrint(keyPath)
}
print("Hello")
Building for debugging...
error: emit-module command failed due to signal 6 (use -v to see invocation)

I'm creating an extension macro in a swift package.
On compiling the executable target that is using my Macro I get the following:
Command SwiftEmitModule failed with a nonzero exit codeSteps to reproduce
This can be reproduced as follows:
Package.swift file with the following:
Sources/MyMacroClient/main.swift:
Sources/KeyPathIterable/KeyPathIterable.swift
Sources/KeyPathIterableMacro/KeyPathIterableMacro.swift
Expected behavior
Macro would compile or give me better compiler errors to fix my code.
Environment

Target: arm64-apple-macosx13.0
