Swift3でリマインダーの作成ボタンが押されたときに2番目のリマインダーを設定する

お客さま向けの予約リマインダーアプリを作成しましたが、予約時だけでなく、前日（24時間）までにアプリで早めに通知してほしいとの声もありましたが、よくわかりません。これを行うためにコードを編集する方法。

これは、日付ピッカーで選択した時間の予定を示す私の作業コードです。

import UIKit
import EventKit

class RemindersViewController: UIViewController {

    @IBOutlet weak var reminderText: UITextField!
    @IBOutlet weak var myDatePicker: UIDatePicker!
    @IBOutlet weak var activityIndicator: UIActivityIndicatorView!
    let appDelegate = UIApplication.shared.delegate
        as! AppDelegate

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

    }

    @IBAction func setReminder(_ sender: AnyObject) {

        if reminderText.text == "" {

            // Create the alert controller
            let alertController = UIAlertController(title: "Information Needed", message: "Please type in your treatment and select the correct date and time you wish to be reminded about before pressing the Create Appointment Reminder button.", preferredStyle: .alert)

            // Create the actions
            let okAction = UIAlertAction(title: "Got It", style: UIAlertActionStyle.default) {
                UIAlertAction in
                NSLog("OK Pressed")
            }

            // Add the actions
            alertController.addAction(okAction)

            // Present the controller
            self.present(alertController, animated: true, completion: nil)

        } else {

            activityIndicator.startAnimating()

            let eventStore = EKEventStore()
            eventStore.requestAccess(
                to: EKEntityType.reminder, completion: {(granted, error) in
                    if !granted {
                        print("Access to store not granted")
                        print(error!.localizedDescription)
                    } else {
                        print("Access granted")
                        self.createReminder(in: eventStore)
                    }
            })
        }

        self.reminderText.resignFirstResponder()
    }

    func textFieldShouldReturn(_ textField: UITextField) -> Bool {

        textField.resignFirstResponder()

        return true
    }

    func createReminder(in eventStore: EKEventStore) {

        let reminder = EKReminder(eventStore: eventStore)

        reminder.title = reminderText.text! + " " + "(Pose Beauty Salon)"
        reminder.calendar =
            eventStore.defaultCalendarForNewReminders()
        let date = myDatePicker.date
        let alarm = EKAlarm(absoluteDate: date)

        reminder.addAlarm(alarm)

        do {
            try eventStore.save(reminder,
                                             commit: true)
        } catch let error  {
            print("Reminder failed with error \(error.localizedDescription)")
        }

        // Create the alert controller
        let alertController = UIAlertController(title: "Reminder Created Successfully", message: "Your \(reminderText.text!) appointment reminder at Pose Beauty Salon has been successfully created in your iPhone Reminders app.  Thank You!", preferredStyle: .alert)

        // Create the actions
        let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) {
            UIAlertAction in
            NSLog("OK Pressed")
            self.reminderText.text = ""
            self.activityIndicator.stopAnimating() 
        }

        // Add the actions
        alertController.addAction(okAction)

        // Present the controller
        self.present(alertController, animated: true, completion: nil)
    }

    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        reminderText.endEditing(true)
    }
}

コードを次のように変更しましたが、リマインダーは1回しか保存されません。

func createReminder(in eventStore: EKEventStore) {

    let reminder = EKReminder(eventStore: eventStore)
    let secondReminder = EKReminder(eventStore: eventStore)

    reminder.title = reminderText.text! + " " + "(Pose Beauty Salon)"
    reminder.calendar =
        eventStore.defaultCalendarForNewReminders()
    secondReminder.title = reminderText.text! + " Tomorrow " + "(Pose Beauty Salon)"
    secondReminder.calendar =
        eventStore.defaultCalendarForNewReminders()
   // let date = myDatePicker.date
    let actualDate = myDatePicker.date
    let earlyReminderDate = actualDate.addingTimeInterval(-3600*24)
    //let alarm = EKAlarm(absoluteDate: date)
    let alarm = EKAlarm(absoluteDate: actualDate)
    let secondAlarm = EKAlarm(absoluteDate: earlyReminderDate)

    reminder.addAlarm(alarm)
    secondReminder.addAlarm(secondAlarm)
