swift build writes to incorrect MacOS path

[iainhouston]

Description

swift’s —show-bin-path option correctly shows the correct path, namely …/.build/arm64-apple-macosx/release but the executable is incorrectly written to …/.build/x86_64-apple-macosx/release

Steps to reproduce

Using the Apple swift-argument-parser sample code on GitHub.

swift build with Package.swift as follows:

// swift-tools-version: 5.7
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "count",
    dependencies: [
      .package(url: "https://github.com/apple/swift-argument-parser.git", from: "1.0.0"),
    ],
    targets: [
        // Targets are the basic building blocks of a package. A target can define a module or a test suite.
        // Targets can depend on other targets in this package, and on products in packages this package depends on.
        .executableTarget(
            name: "count",
            dependencies: [.product(name: "ArgumentParser", package: "swift-argument-parser")]),
    ]
)

Expected behaviour

The executable should be written using the path as displayed by the —show-bin-path option , namely …/.build/arm64-apple-macosx/release

Environment

• Swift compiler version info

MacOS Ventura 13.0.1 Using Apple Swift version 5.7.1

• Xcode version info: N/A as I am building a script from the command swift build
• Deployment target: none explicitly stated in Package.Swift

Added transfer candidate because that sounds like a SPM or driver issue? But requires to take a more detailed look to confirm

@ddunbar Does this look like a SPM issue to you?

[tomerd]

if true, then this would be a SwiftPM bug. please move over to the SwiftPM repo.

I cannot reproduce this. I'm assuming this is on an arm64 host?

Could you run swift package clean && swift build --verbose and post the resulting output here?
