Create a simple dylib in objective c macos

Job ID: 35120399

Budget: $10 – $30 USD

I need a simple macos library which is programmed in objective c.
The library must contain one function which accepts the handle of the window.
Then with the handle it must cast to NSWindow and change the title of that window.
The library must be testable by another swift project which creates the window and sends the handle to the library which changes the title of the widnow.
