"Application is agent" doesn't work in Swift

Question

I'm working on a status bar app in Swift. I tried to hide the window by adding Application is agent (UIElement) item and set it to YES, but it just doesn't work - it always shows the window and the menu bar.

My storyboard:

Info.plist:

What can I do ?

Answer 1

The option for "Target -> Info -> Curstom macOS Appli.. : Application is agent (UIElement)" only hide the App from Dock

To hide the window on SwiftUI you need to change your App Scene:

var body: some Scene {
    Settings{
        EmptyView()
    }
}

Alternatively you can change the ApplicationDelegate

func applicationDidFinishLaunching(_ notification: Notification) {
    if let window = NSApplication.shared.windows.first {
        window.close()
    }
    ...
 }
