Super interesting that they're using swift. Does this mean the project is only a wrapper for system libraries ? I can't imagine writing low-level system code in swift yet.
From Apple's point of view it is perfectly fine for such purposes.

Swift goes further down the stack than you might at first imagine -- there's a lot of Swift written at Apple even in places where you might expect C.
The container CLI tool wraps the underlying Containerization framework, which in turn vends packages for things like EXT4 file system support -- all written in Swift. Here's one example as a jumping off point.

From my point of view, if Go does it, Swift is much better at the same game.

This project is very similar to docker with a background daemon server that you control via a cli to launch Linux containers.
Because Linux containers need Linux namespaces, each container is run in a virtual machine with a Linux kernel.
