Swift: Bug when try to access value of object in array - swift

Question

I encounter a very strange bug, I have a PodEvent type array, and with a second function I get another array that I cast, when I make a print of the casted array with the result it shows me all the objects of the board...
PodEvent {
eventID = 2;
podID = 1;
drinkDate = 2018-09-25 10:00:00 +0000;
actualDrinkingTime = (null);
keyDate = 2018-09-25 13:00;
rawState = Forgotten;
}
But when I want to access the value of the object it returns to me as the default values! for example:
print(self.podEvents[1].eventID)
print(self.podEvents[1].podID)
outpout:
-1
-1
Here my class:
class PodEvent: Object {
#objc var eventID: Int = -1
#objc var podID: Int = -1
#objc var drinkDate: Date = Date()
#objc var actualDrinkingTime: Date? = Date()
var state: PodState = .future
#objc var keyDate: String = ""
#objc private var rawState: String!
convenience init(eventID: Int, podID: Int, drinkDate: Date, actualDrinkingTime: Date?, state: PodState){
self.init()
self.eventID = eventID
self.podID = podID
self.drinkDate = drinkDate
self.actualDrinkingTime = actualDrinkingTime
self.state = state
self.rawState = state.state
}
func setState(state: PodState){
self.state = state
rawState = state.state
}
override class func primaryKey() -> String? {
return "keyDate"
}
This bug is very strange
My code to fetch my array:
//Fetch pod history in internal database
self.databaseManager.fetch(object: PodEvent.self, predicate: nil, sortedBy: "keyDate", ascending: true) { success, results, error in
guard error == nil else {
Alerts.alertMessage(for: self, title: "ERROR".localized,
message: error!.localizedDescription,
closeHandler: nil)
return
}
self.podEvents = (results as! [PodEvent])
self.pods = pods
print(self.podEvents[1].eventID)
print(self.podEvents[1].podID)
}
and:
func fetch(object: Object.Type, predicate: NSPredicate?, sortedBy: String, ascending: Bool, completion: DatabaseCompletion?) {
do {
let realm = try Realm()
let objects: Results<Object>!
if let predicate = predicate {
objects = realm.objects(object).filter(predicate).sorted(byKeyPath: sortedBy, ascending: ascending)
} else {
objects = realm.objects(object).sorted(byKeyPath: sortedBy, ascending: ascending)
}
let objectsArray = Array(objects)
completion?(true, objectsArray, nil)
} catch let error {
print("Could not write object (type \(object)) to Realm:", error.localizedDescription)
completion?(false, nil, error)
}
}
im using realm

Your object definition is flawed, you need to add the dynamic keyword to all persisted properties.
class PodEvent: Object {
#objc dynamic var eventID = -1
#objc dynamic var podID = -1
#objc dynamic var drinkDate = Date()
#objc dynamic var actualDrinkingTime: Date? = Date()
var state: PodState = .future
#objc dynamic var keyDate = ""
#objc dynamic private var rawState: String!
...
}
