I'm able to programmatically create menu items using the following code.
primaryMenu.addItem(NSMenuItem(title: "MenuTitle", action: nil, keyEquivalent: ""))
I want to be able to update the title from this menu item. I have been able to do it very easily when I manually create the menu using Interface Building.
I don't have a way to identify the menu item.
Store a reference to your NSMenuItem
(such as in an instance variable), and set the title on it whenever you wish:
let myMenu = NSMenuItem(title: "MenuTitle", action: nil, keyEquivalent: "")
primaryMenu.addItem(myMenu)
//somewhere else:
myMenu.title = "xyz"
