I have made these changes to the code   func loadData() {     self.reminders.removeAll()     let ref = Database.database().reference()     ref.child("usersEvents").observeSingleEvent(of: .value, with: { (snapshot) in       if let reminderDict = snapshot.value as? [String:AnyObject] {         print(reminderDict)    // Just to check         for (_,reminderElement) in reminderDict {           if let remindIt = reminderElement as? [String: Any] {  // Cast AnyObject to [String: Any]             let reminder = Reminders             reminder.event = (remindIt["event"] as? String) ??             reminder.dateAndTime = (remindIt["data and time"] as? String) ?? // <<-- Is the key data and             reminder.message = (remindIt["notes"] as? String) ??             self.reminders.append(reminder)           }         }       }         }, withCancel: { (error) in       print(error.localizedDescription)             })     However I keep getting the error messages let reminder = Reminders Cannot find 'Reminders' in scope and self.reminders.append(reminder) Cannot convert value of type '()' to expected argument type 'String' I am unsure of what the " let reminder = Reminders:" is meant to be. I assume that it connects and stores the variables however I am unsure. It has been the biggest problem I have faced so far and just cant wrap my head around it.

Thank you for the reply, apologies I did not see your response on my other post and I am new to the language. I am unsure of what you mean by call reminders[someIndex].dateAndTime or more probably reminder.dateAndTime (not reminders with an s). When i change let reminder = Reminder()   reminders.event = reminderElement["event"] as? String     reminders.dateAndTime = reminderElement["data and time"] as? String           reminders.message = reminderElement["notes"] as? String           self.reminders.append(reminder) to this let reminder = reminders reminder.event = reminderElement["event"] as? String reminder.dateAndTime = reminderElement["data and time"] as? String reminder.message = reminderElement["notes"] as? String self.reminders.append(reminder) I just get a bunch of errors. I am not sure if I understand what it is your saying to do or if I have missed a step

When I made the adjustments to the code I keep getting one error Cannot find 'of' in scope I keep getting this error here. ref.child("usersEvents").observeSingleEvent(of .value, with: { (snapshot) in This is the new code with the adjustments made I have made every change I can think of but just cant get it to go away import UIKit import FirebaseAuth import Firebase import FirebaseDatabase import FirebaseFirestore class DashboardViewController: UIViewController {   @IBOutlet weak var reminderList: UITableView!   var reminders = [EntryViewController]()      override func viewWillAppear(_ animated: Bool) {      super.viewWillAppear(animated)      loadData()   }     func loadData() {   self.reminders.removeAll()   let ref = Database.database().reference()   ref.child("usersEvents").observeSingleEvent(of .value, with: { (snapshot) in     if let reminderDict = snapshot.value as? [String:AnyObject] {       for (_,reminderElement) in reminderDict {         print(reminderElement);         let reminder = Reminder()         reminders.event = reminderElement["event"] as? String         reminders.dateAndTime = reminderElement["data and time"] as? String         reminders.message = reminderElement["notes"] as? String         self.reminders.append(reminder)                 }             }     self.tableView.reloadData() // Should it be inside the if let ?              }, withCancel: { (error) in     print(error.localizedDescription)         })               func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {     return self.reminders.count   }   func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {     if let cell = tableView.dequeueReusableCell(withIdentifier: "ToDoCell") {       var content = cell.defaultContentConfiguration()       content.text = reminders[indexPath.row].event       cell.contentConfiguration = content       return cell      } else {        return UITableViewCell()      }   }     }     }
