Kernel / OS written with Embedded Swift https://github.com/bastie/SOS SOS is an Embedded Swift bare metal implementation on ARM64 platform. aarch64-none-none-elf https://github.com/spevans/swift-project1 A project to write a kernel in Swift that can run on x86_64 hardware. x86_64-none-unknown-elf https://github.com/MauriceElliott/MAGIos MAGIos is experimental. It is a conduit for me to learn how an OS works as well as giving me an outlet for creativity. riscv64-none-none-eabi
