Question: data attribute for macos_command_line_application or alternative

[stepango]

I want to run my python script(py_binary) from Swift and I ended up having the following setup, which compiles without an issue

swift_library(
    name = "Sources",
    srcs = ["main.swift"],
    visibility = ["//visibility:public"],
    data = ["//src/image_gen:main"], # py_binary
)

apple_bundle_version(
    name = "CommandLineSwiftVersion",
    build_version = "1.0",
)

macos_command_line_application(
    name = "CommandLineSwift",
    bundle_id = "com.example.command-line-swift",
    infoplists = [":Info.plist"],
    minimum_os_version = "13.6",
    version = ":CommandLineSwiftVersion",
    deps = [
        ":Sources",
    ],
)

According to docs, py_binary runfiles are supposed to end up in CommandLineSwift's bin folder(transitively trough swift_library), but Somehow py_binary runfiles never end up in there

However, the other way around - works. I can add CommandLineSwift to py_binary data attribute without any issues. Am I doing smth wrong here? Is there other way to do it?
