title: Set a second reminder when create reminder button pressed in Swift 3
body: <p>I've created an appointment reminder app for customers but a few have said they would like the app to give them an earlier notification say one day in advance (24 hours) as well as at the time of the appointment, but I'm unsure how I can edit my code to do this.</p>
  
  <p>Here is my working code that shows the appointment at the chosen time on the date picker:</p>
  
  <pre><code>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) -&gt; 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&lt;UITouch&gt;, with event: UIEvent?) {
          reminderText.endEditing(true)
      }
  }
  </code></pre>
  
  <p>I've changed my code as follows but I only get the reminder saved once:</p>
  
  <pre><code>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)
  </code></pre>
