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
},
failure: { error in
print("oh no!")
})The package can be installed through SwiftPM.

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