Swift System

Swift System provides idiomatic Swift interfaces to low-level system calls and types, aiming to be the canonical home for these building blocks on all supported Swift platforms. It wraps platform details behind portable APIs while still allowing you to drop down to exact OS semantics when needed. The design follows Swift’s value semantics and protocol orientation to keep code predictable and testable. It’s distributed via SwiftPM with tagged releases, making it straightforward to pin versions in larger stacks. Over time, the library is intended to centralize foundational syscalls so other packages don’t reinvent thin wrappers. Escape hatches to exact platform behaviors when required. This consolidation improves consistency, documentation quality, and cross-platform behavior for systems programming in Swift. Portable, idiomatic wrappers for system calls and types.
