class WebViewLogPlugin: WebViewPluginProtocol {

    func log(_ msg: Any) {
        print(msg)
    }
    
    // MARK: - WebViewPluginProtocol
    var identifier: String {
        return "holo.webView.bridge.log"
    }
    
    var javascript: String {
        return """
        window.bridge.log = function(msg) {
            window.bridge.js_msgSend("holo.webView.bridge.log", "log()", msg)
        }
        """
    }
    
    func didReceiveMessage(_ fun: String, args: Any?) {
        if fun == "log()" {
            self.log(msg ?? "")
        }
    }
}

3, Call function in JS

window.bridge.log("hello world")

Note that if your JS methods are complex, you can also define the JS method in a .js file and return the contents of the file in the var javascript: String { get } protocol method, like WebViewAlertPlugin.swift & alert.js.
