swift - Not able to load WebView on button click -

i trying load url on dynamically created webview when user clicks on button nothing loads.

code :

import cocoa import webkit  class viewcontroller :nsviewcontroller {      override func viewdidload() {         super.viewdidload()          // additional setup after loading view.     }      override var representedobject: any? {         didset {         // update view, if loaded.         }     }      @ibaction func mybutton(_ sender: any) {         let url = url(string: "https://www.google.com")         let request = urlrequest(url: url!)         let webview =  webview(frame: nsrect(x: 0, y: 0, width: 400, height: 400))         webview.mainframe.load(request)     }  } 

you still have add webview subview of viewcontroller:

@ibaction func mybutton(_ sender: any) {     let url = url(string: "https://www.google.com")     let request = urlrequest(url: url!)     let webview =  webview(frame: nsrect(x: 0, y: 0, width: 400, height: 400))     webview.mainframe.load(request)     self.view.addsubview(webview) }
