Deliver an OSX notification with Swift

notification.swift

func showNotification() -> Void {
    var notification = NSUserNotification()
    notification.title = "Test from Swift"
    notification.informativeText = "The body of this Swift notification"
    notification.soundName = NSUserNotificationDefaultSoundName
    NSUserNotificationCenter.defaultUserNotificationCenter().deliverNotification(notification)
}

//showNotification()

@ixeau Without NSUserNotificationCenterDelegate your notification will be shown only into the Notification center. If you want to have the popup and probably interact with your Notification you need NSUserNotificationCenterDelegate.
Example:

func showNotification() -> Void {
            let notification = NSUserNotification()
            notification.title = "Test."
            notification.subtitle = "Sub Test."
            notification.soundName = NSUserNotificationDefaultSoundName
            NSUserNotificationCenter.default.delegate = self
            NSUserNotificationCenter.default.deliver(notification)
}

func userNotificationCenter(_ center: NSUserNotificationCenter,
                                         shouldPresent notification: NSUserNotification) -> Bool {
        return true
}

This will show the top-right popup.

Thanks @Valerio69 that worked for me, I was missing NSUserNotificationCenter.default.delegate = self

Thanks @Valerio69. Thank you so much, I could have an app that pops up notification upper-right of the screen.
