is this à replacement for docker ? 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 its earliest conception, Swift was built to be fast. Using the incredibly high-performance LLVM compiler technology, Swift code is transformed into optimized machine code that gets the most out of modern hardware. The syntax and standard library have also been tuned to make the most obvious way to write your code also perform the best whether it runs in the watch on your wrist or across a cluster of servers. And Swift is the best choice to succeed C++. It includes low-level primitives such as types, flow control, and operators, and provides object-oriented features such as classes, protocols, and generics.

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