How to make multiple local notifications in Swift?

Question

Swift

The bottom line is that I made one local notification at a time interval of 10 seconds.
How to add multiple notifications to this code with different time delay? That is, different notifications with different delays (several hours, days, etc.).
If it is possible, then on the example of my code, please.

import UIkit
import UserNotifications

class ViewController UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        let center = UNUserNotificationCenter.current()
        
        let content = UNMutableNotificationContent()
        
        content.title = "Hi"
        content.body = "Bear"
        content.sound = UNNotificationSound.default
        content.threadIdentifier = "local-notifications"
        
        let date = Date(timeIntervalSinceNow: 10)
        
        let dateComponents = Calendar.current.dateComponents([.year, .month, .day, .hour, .minute, .second], from: date)
        
        let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: false)
        
        let request = UNNotificationRequest(identifier: "content", content: content, trigger: trigger)
        
        center.add(request) {(error) in 
            if error != nil {
                print (error)
            }
        }
    }

Put different and different time. PS I strongly do not recommend copy-pasting the code, understand how it works - then such questions will not appear. And you will know more. identifier: "content"
