Lets say I use https://github.com/vtourraine/AcknowList

Some nice people put it on GitHub so people like me can make apps with it. But, what if the tap was turned off and the owners of the repository made it a private repo? What if my beautiful app was in source control, but my copy of AcknowList was now seemingly lost forever?

In other languages, like Java, I guess I could maintain copies of the library, which is probably a jar, in my artifact repository.

If I am super paranoid about this what should I do?

Fork the repo?
Put it into my artefact repository somehow?
Something else?
Thank you in advance

I’ve researched options and haven’t found anything else. I would expect that swift packages could be easily published and put into an artifact repository.
