Bug Description

The setup mentioned in the docs for SwiftPlugin doesn't work when executed with clonedSourcePackagesDirPath:
xcodebuild -clonedSourcePackagesDirPath ".build"

SWIFT_PACKAGE_DIR="${BUILD_DIR%Build/*}SourcePackages/artifacts"
SWIFTLINT_CMD=$(ls "$SWIFT_PACKAGE_DIR"/swiftlintplugins/SwiftLintBinary/SwiftLintBinary.artifactbundle/swiftlint-*/bin/swiftlint | head -n 1)

if test -f "$SWIFTLINT_CMD" 2>&1
then
    "$SWIFTLINT_CMD"
else
    echo "warning: `swiftlint` command not found - See https://github.com/realm/SwiftLint#installation for installation instructions."
fi

Packages are then stored in a that folder, not the %BUILD_DIR.

Environment

• SwiftLint version: any
• Xcode version: 15.0, 16.0
