osx - Adding the WebView to NSPopover doesn't show the WebView, just the NSView -

in appdelegate init() have

 popover = nspopover()  popover.behavior = .transient  popover.contentviewcontroller = contentviewcontroller() 

now in contentviewcontroller : nsviewcontroller

 override func loadview() {          view = nsview()         view.translatesautoresizingmaskintoconstraints = false         view.addconstraint(nslayoutconstraint(             item: view, attribute: .width, relatedby: .equal,             toitem: nil, attribute: .notanattribute, multiplier: 1.0, constant: 580))         view.addconstraint(nslayoutconstraint(             item: view, attribute: .height, relatedby: .equal,             toitem: nil, attribute: .notanattribute, multiplier: 1.0, constant: 425))          nsuserdefaults.standarduserdefaults().registerdefaults(["useragent": "tick mac app"])         let url = nsurl(string: tickextensionurl )!         var request = nsurlrequest(url: url)          var webview = webview(frame: view.bounds)         webview.mainframe.loadrequest(request)         view.addsubview(webview)      } 

as can see view appears not webview. doing wrong?

you have tell controller whats view add @ end of load view

self.view = view
