NSStatusItem links klicken

Question

Erstens: Ich bin neu mit Swift Entwicklung.
Ich benutze this Tutorial, um ein Popup zu erstellen, das erscheint, wenn ich auf meine obere Leiste Symbol klicke.

Also mein AppDelehgate Code ist:

func applicationDidFinishLaunching(_ aNotification: Notification){ 
    print("START !"); 
    if let button = statusItem.button { 
     button.image = NSImage(named: "logo"); 
     button.action = Selector(("togglePopover:")); 
     //button.target = self; 
    } 

    popover.contentViewController = QuotesViewController(nibName: "QuotesViewController", bundle: nil); 
} 

func togglePopover(envoyeur: AnyObject?){ 
    print("TOGGLE !"); 
    if popover.isShown{ 
     closePopover(sender: envoyeur) 
    } else { 
     showPopover(sender: envoyeur) 
    } 
} 

aber nie die "TOGGLE!" Text erscheint, das Ereignis funktioniert nicht.
Ich habe die "button.target = self;" in Kommentar, weil es abstürzt, wenn ich es nicht mache. Das Ereignis scheint die trigged sein, aber ich habe einen Fehler bekommt:

START !

die #selector Syntax Swift Verwenden

button.action = #selector(togglePopover(_:)) // or just #selector(togglePopover)
