How to compile Swift from the command line for distribution

Question

I have one Swift script command line file (it uploads the contents of the menu bar with the process identifier).

To give an idea of ​​the APIs I use, here are a few relevant lines:

import Foundation
import Cocoa

// ...
func getAttribute(element: AXUIElement, name: String) -> CFTypeRef? {
    var value: CFTypeRef? = nil
    AXUIElementCopyAttributeValue(element, name as CFString, &value)
    return value
}

// ...
var app: NSRunningApplication? = nil
if pid == -1 {
    app = NSWorkspace.shared().menuBarOwningApplication
}
else {
    app = NSRunningApplication(processIdentifier: pid)
}

// ...
let axApp = AXUIElementCreateApplication(app.processIdentifier)

The whole file is available here .

When I compile this with swiftc menu.swift, I can just run it on my system where Swift is installed.

When I transfer the executable to menusomeone who does not have Swift, they get the following error when starting through Terminal:

Code 6: dyld: Library not loaded: @rpath/libswiftAppKit.dylib
  Referenced from: ./menu
  Reason: image not found

I suppose I need to statically link something, but I'm not sure. I cannot verify this easily since I do not have access to the macOS assembly without Swift.

swiftc, script, macOS?
