ci: add EXCLUDED_ARCHS=x86_64 to eliminate redundant x86_64 builds#306
Merged
Conversation
SPM dependency targets (ArgumentParser, ZIPFoundation, macOSdbKit) were being fully compiled and linked for x86_64 in addition to arm64 because `EXCLUDED_ARCHS` was only set at the app target level, not propagated to SPM-generated targets. This added ~30 redundant SwiftCompile steps plus linking — overhead that also slowed CodeQL tracing. Add `EXCLUDED_ARCHS=x86_64` at the project level in `project.pbxproj` (covers Xcode GUI builds) and as a command-line override on all `xcodebuild` invocations in the justfile and CI workflows (covers CLI and CI builds).
