Is there a new way to create, execute and manage processes to run command line tools in macOS?

Yes, there is a new way to create, execute, and manage processes to run command line tools in macOS. Apple introduced a new framework called Containerization, which provides a command line tool that lets you create, download, and run Linux container images right on your Mac. This tool is built on an open-source framework optimized for Apple Silicon and provides secure isolation between container images. You can learn more about this in the session Meet Containerization.

Additionally, the session What’s new in Swift introduces a new package with APIs for launching subprocesses, which can be used for scripting tasks. This package allows you to start subprocesses by calling the run function and awaiting the result, streamlining the process of managing command line tools.
