You can check the JavaScriptCore framework to evaluate JavaScript. it is native iOS framework.

let context = JSContext()

let _ = context?.evaluateScript(evaluateScriptJSCode)

let method = context?.objectForKeyedSubscript("methodToCallInJavaScript")

let result = method?.call(withArguments: [params])
