I'm trying to use transformable with my entity class. Is that possible? if so how can i do that? It's my core data properties code import Foundation import CoreData extension PersonEntity {   @nonobjc public class func fetchRequest() -> NSFetchRequest<PersonEntity> {     return NSFetchRequest<PersonEntity>(entityName: "PersonEntity")   }   @NSManaged public var gender: String?   @NSManaged public var id: UUID?   @NSManaged public var name: String?   @NSManaged public var volunteered: Bool   @NSManaged public var schedules: NSSet? } // MARK: Generated accessors for schedules extension PersonEntity {   @objc(addSchedulesObject:)   @NSManaged public func addToSchedules(_ value: ScheduleEntity)   @objc(removeSchedulesObject:)   @NSManaged public func removeFromSchedules(_ value: ScheduleEntity)   @objc(addSchedules:)   @NSManaged public func addToSchedules(_ values: NSSet)   @objc(removeSchedules:)   @NSManaged public func removeFromSchedules(_ values: NSSet) } extension PersonEntity : Identifiable { } and it's my core data class import CoreData @objc(PersonEntity) public class PersonEntity: NSManagedObject, NSSecureCoding {   public static var supportsSecureCoding: Bool = true       enum Key: String {     case id = "id"     case name = "name"     case gender = "gender"     case volunteered = "volunteered"   }       init(id: UUID, name: String, gender: String, volunteered: Bool) {     self.id = id     self.name = name     self.gender = gender     self.volunteered = volunteered // I'm getting Error here // Must call a designated initializer of the superclass 'NSManagedObject'     super.init(entity: , insertInto: )   }       public func encode(with coder: NSCoder) {     coder.encode(id, forKey: Key.id.rawValue)     coder.encode(name, forKey: Key.name.rawValue)     coder.encode(gender, forKey: Key.gender.rawValue)     coder.encode(volunteered, forKey: Key.volunteered.rawValue)   }       required convenience public init?(coder: NSCoder) {     let decodedId = coder.decodeObject(forKey: Key.id.rawValue)     let decodedName = coder.decodeObject(forKey: Key.name.rawValue)     let decodedGender = coder.decodeObject(forKey: Key.gender.rawValue)     let decodedVolunteered = coder.decodeObject(forKey: Key.volunteered.rawValue)     self.init(id: decodedId as! UUID, name: decodedName as! String, gender: decodedGender as! String, volunteered: (decodedVolunteered != nil))   } } I'm really new here... sorry
