@seanchas116 made a Swift port of my minimal example https://github.com/seanchas116/SimpleDALPlugin
Overall it _was_ very difficult! Apple's documentation and sample code for CoreMediaIO DAL (virtual camera) plugins are terrible. I just brute forced it for hours trying all sorts of different combinations of things before I got something to work.
... and apples examples are in c++ but i ended up doing it using straight c out of frustration since thier (c++) examples were so convoluted
