SwiftWebAssembly

SwiftWebAssembly has one purpose, to load WebAssembly compiled modules and exposes them to Swift.

Example

import SwiftWebAssembly
import JavaScriptCore

let context = JSContext()
let file = URL(fileURLWithPath: "example.wasm")
let data = try! Data(contentsOf: file)

context.loadWebAssemblyModule(data: data, success: { exports in
    let result = exports?["add"]?.call(withArguments: [1, 2])
    print("result: \(result)") // result: 3
})

Integration

Swift Package Manager

The package can be installed through SwiftPM.

  .package(url: "[email protected]:therealbnut/SwiftWebAssembly.git", from: "0.2.0"),

A more complete example:

// swift-tools-version:4.0
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(

        .package(url: "[email protected]:therealbnut/SwiftWebAssembly.git", from: "0.2.0"),
