Gamepad is recognised in Comand Line app, but not in a Cocoa app

I can't get GameController class working with my joystick. However I found a simple library https://github.com/suzukiplan/gamepad-osx using IOKit written is C, and got it working in swift command line app using the following code for main.swift:

import Foundation
   
    func  callback(_  type: Int32, _ page: Int32,  _ usage: Int32, _ value: Int32) -> Void  {
        print("Type: \(type); page: \(page), usage: \(usage), value: \(value)")
    }
   
    let ctx = gamepad_init(1, 1, 0)
   
    if ctx == nil {
        print("Init  failed")
        exit(4)
    }
   
    gamepad_set_callback(ctx, callback(_:_:_:_:))
   
    CFRunLoopRun()
    exit(0)

Console messages:

    attched device: Controller
    attched device: 2.4G RX
    attched device: VirtualHIDKeyboard
    Type: 2; page: 7, usage: 227, value: 1
    Type: 2; page: 7, usage: -1, value: 6
    ....

Since I am actually targeting MacOS app, I created a single-view Cocoa app with the following (very similar) code in Main View:

   import AppKit
   
    class MainView: NSView {
   
        required init?(coder decoder: NSCoder) {
            super.init(coder: decoder)

            print("Init started")
           
            let ctx = gamepad_init(1, 1, 0)
            if ctx == nil {
               print("Init  failed")
               return
           }
   
            print("Init succeeded")
   
            gamepad_set_callback(ctx, callback(_:_:_:_:))
   
            print("Callback attached")
   
        }
    }
   
    func  callback(_  type: Int32, _ page: Int32,  _ usage: Int32, _ value: Int32) -> Void  {
        print("Type: \(type); page: \(page), usage: \(usage), value: \(value)")
    }

The window appears, but console output has only that:

    Initialising started
    Initialising succeeded
    Callback attached

No attachment messages, and quite obviously no callback from device

Also tried an running and additional thread (DispatchQueue) in Main view and in AppDelegate

    func applicationDidFinishLaunching(_ aNotification: Notification) {
       DispatchQueue(label: "Joy").async {
            print("Initialising started")

            let ctx = gamepad_init(1, 1, 0)
            if ctx == nil {
                print("Init  failed")
                return
            }
       
            print("Initialising succeeded")
            gamepad_set_callback(ctx, callback(_:_:_:_:))
   
           CFRunLoopRun()
       }
    }

Again, no attachment messages

Any ideas?
