func notifyme(){
    
    print("notification will be triggered in five seconds..Hold on tight")
    let content = UNMutableNotificationContent()
    content.title = "Intro to Notifications"
    content.subtitle = "Lets code,Talk is cheap"
    content.body = "Sample code from WWDC"
    content.sound = UNNotificationSound.default()
    
    //To Present image in notification
    if let path = Bundle.main.path(forResource: "monkey", ofType: "png") {
        let url = URL(fileURLWithPath: path)
        
        do {
            let attachment = try UNNotificationAttachment(identifier: "sampleImage", url: url, options: nil)
            content.attachments = [attachment]
        } catch {
            print("attachment not found.")
        }
    }
    
    // Deliver the notification in five seconds.
    //let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 5.0, repeats: false)
    
    
    var dateComponents = DateComponents()
    dateComponents.hour = 12
    dateComponents.minute = 13
    let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)

    let request = UNNotificationRequest(identifier:requestIdentifier, content: content, trigger: trigger)
    
    UNUserNotificationCenter.current().delegate = self
    UNUserNotificationCenter.current().add(request){(error) in
        
        if (error != nil){
            
            print(error?.localizedDescription as Any)
        }else{
            
        //    print("Notifcation is there.")
            
            
        }
    }
}

This is what i have done for daily notification but i want notification on alternate days.
