NSStatusItem icon randomly dissappearing

Question

I'm trying to figure out a weird problem that's happening with my menu bar app. It would run perfectly fine for a couple of hours or even days but would randomly disappear from the menu bar.

In activity monitor, it's still running in the background. There's a global keyboard shortcut in the app to show the window and it brings out the app no problem but the menu bar icon is still missing.

I'm on macOS Monterery 12.2.1

StatusBarController

class StatusBarController {
    private var statusBar: NSStatusBar
    private var statusItem: NSStatusItem
    public var popover: NSPopover
    private var eventMonitor: EventMonitor?
    
    init(_ popover: NSPopover)
    {
        self.popover = popover
        statusBar = NSStatusBar.init()
        statusItem = statusBar.statusItem(withLength: 28.0)
        
        if let statusBarButton = statusItem.button {
            statusBarButton.image = #imageLiteral(resourceName: "link")
            
            statusBarButton.image?.size = NSSize(width: 18.0, height: 18.0)
            statusBarButton.image?.isTemplate = true
            
            statusBarButton.action = #selector(togglePopover(sender:))
            statusBarButton.target = self
        }
        

    }
.......}

App Delegate

@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {
    var popover = NSPopover.init()
    var statusBar: StatusBarController?
    

    func applicationDidFinishLaunching(_ aNotification: Notification) {
        // Create the SwiftUI view that provides the contents
        let contentView = ContentView()

        // Set the SwiftUI's ContentView to the Popover's ContentViewController
        popover.contentViewController = MainViewController()
        popover.contentViewController?.view = NSHostingView(rootView: contentView)
        popover.animates = false
     
        
        KeyboardShortcuts.onKeyUp(for: .triggerPopover, action: {
            self.statusBar?.togglePopover(sender: self)
        })
        
        // Create the Status Bar Item with the Popover
        statusBar = StatusBarController.init(popover)
    }


    
}

Have you tried the system status bar `NSStatusBar.system`? See [About Status Bars](https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/StatusBar/Concepts/aboutstatusbars.html#//apple_ref/doc/uid/20000995-CJBJFCCH) "Only one status bar, the system status bar, is currently available" and "If the status bar extends into the current application’s menu bar, the leftmost status items are hidden to make room for the menus." — Willeke, Aug 04 '22 at 07:04
Wow, i didn't know that! always thought NSStatusBar would be the systems by default. I'll try that and test again. If that works i'll come back and let you know. Thank You! — swiftnoob, Aug 04 '22 at 07:26
problem is gone! :-) if you can post your comment as an answer I'll mark at is as solved. — swiftnoob, Aug 13 '22 at 17:10

From Status Bar Programming Topics:

A system-wide status bar resides at the right side of the menu bar and is the only status bar currently available.

NSStatusBar.init() doesn't return the system status bar. Use NSStatusBar.system instead.
