This reminds me of Node.js fs module that enables interacting with the file system on standard POSIX functions. Probably in 2030 we will have GPT-400 wrapping all of this primitive functions again and we will be relieved that progress is being made once again.
Except Swift is developed by apple with Systems integrating the *NIX functions within a BSD foundation.
Very shrewd from Apple, with linux on ARM looking the next big leap for cloud computing (amazon etc) being able to program in swift natively on a mac running apple silicon and host in an ARM box on the cloud, having open sourced the systems api, is a very attractive offering.
