How to give an NSPopover focus when NSStatusItem is clicked?

Question

I am building a macOS menubar app in Swift, using an NSStatusItem, which opens an NSPopover when the NSStatusItem's button is clicked.

How can I also give the NSPopover focus? Currently, the user needs to click on the popover to focus it, but I want to grab focus programmatically.

Thanks in Advance

The solution is to call makeKey() on the owning window.

This can be done either from the main NSApplicationDelegate, e.g.

func applicationDidFinishLaunching(_ aNotification: Notification) {

     // Other setup

     popover.contentViewController?.view.window?.makeKey()
}

Or from the relevant NSViewController, e.g.

override func viewDidAppear() {
    super.viewDidAppear()
    view.window?.makeKey()
}
