How to organize interaction between the browser component and the site in xcode?

Question

Apple Xcode

We created an application, marked up a web view in it, asked it to open a specific site, how to make it so that when a button is pressed on the site, an action is performed inside the xcode application.
An example from QT: there is a QWebChannel class that, by raising a websocket server inside a QT application and a special JavaScript library that is built into the site and sends commands via the QT websocket protocol to the application, provides the necessary interaction. How to do something like this in xcode?
