WasmKit

A WebAssembly runtime written in Swift. Originally developed and maintained by @akkyie.

Implements all of WebAssembly 2.0 binary parsing and execution core spec, with an exclusion of SIMD instructions. The validation and text format parts of the spec are not implemented yet.

It also has rudimentary support for WASI with only a few WASI imports implemented currently, with a goal of eventual full support for wasi_snapshot_preview1. See WASI module for more details.
