In macOS, how can I use UnmutableNotificationContent notifications to prevent the main window from activating when clicking the notification?
code:
import Cocoa
import UserNotifications // Mandatory import for notification functionality
class ViewController: NSViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Automatically request permissions and send a test notification when the view loads
sendLocalNotification()
}
/// Core method to send a local notification
func sendLocalNotification() {
let notificationCenter = UNUserNotificationCenter.current()
// 1. Request notification permissions (Mandatory step; user approval required)
notificationCenter.requestAuthorization(options: [.alert, .sound, .badge]) { [weak self] isGranted, error in
guard let self = self else { return }
// Handle permission request errors
if let error = error {
print("Permission request failed: \(error.localizedDescription)")
return
}
// Exit if user denies permission
if !isGranted {
print("User denied notification permissions; cannot send notifications")
return
}
// 2. Construct notification content using UNMutableNotificationContent
let notificationContent = UNMutableNotificationContent()
notificationContent.title = "Swift Notification Test" // Notification title
notificationContent.subtitle = "macOS Local Notification" // Optional subtitle
notificationContent.body = "This is a notification created with UNMutableNotificationContent" // Main content
notificationContent.sound = .default // Optional notification sound (set to nil for no sound)
notificationContent.badge = 1 // Optional app icon badge (set to nil for no badge)
// 3. Set trigger condition (here: "trigger after 3 seconds"; can also use time/calendar triggers)
let notificationTrigger = UNTimeIntervalNotificationTrigger(
timeInterval: 3, // Delay in seconds
repeats: false // Whether to repeat (false = one-time only)
)
// 4. Create a notification request (requires a unique ID for later cancellation if needed)
let notificationRequest = UNNotificationRequest(
identifier: "SwiftMacNotification_001", // Unique identifier
content: notificationContent,
trigger: notificationTrigger
)
// 5. Add the request to the notification center and wait for triggering
notificationCenter.add(notificationRequest) { error in
if let error = error {
print("Notification delivery failed: \(error.localizedDescription)")
} else {
print("Notification added to queue; will trigger in 3 seconds")
}
}
}
}
}

In macOS, when using UNMutableNotificationContent to send notifications, clicking on the notification (or the buttons on the notification) will automatically activate the window. How can this be prevented?
Clicking on the notification only triggers the click event and does not activate the window.
