Internal module; not exported from main entry.

Transpile a simple Swift function to JavaScript using Shift.js API.

const shift = require('shift-js'); const swiftCode = ` func greet(name: String) -> String { return "Hello, " + name + "!" } let result = greet(name: "World") print(result) `; shift.transpile(swiftCode).then(js => { console.log(js); }).catch(err => { console.error(err); });

breakingRequires Node 4.0.0+; may not work with modern Node versions due to deprecated APIs.
fix
Use Node 4.x or a compatible runtime; upgrade not recommended.
affects: >=0.1.0
gotchaOnly supports a subset of Swift; complex features like generics or protocols may fail.
fix
Stick to basic Swift constructs or transpile manually.
affects: >=0.0.0
deprecatedDependencies include Bluebird and Commander.js; these may be outdated with security vulnerabilities.
fix
Audit dependencies or use isolated environment.
affects: >=0.1.0
Errors
Common errors & fixes
