Doesn’t encode object with NSSet? property

[ns-vasilev]

I'm trying to encode the following model:

final class ManagedHabit: NSManagedObject, CoreDataCodable {
    @NSManaged var id: String
    @NSManaged var name: String
    @NSManaged var notifications: NSSet?
    
    enum CodingKeys: String, CoreDataCodingKey {
        case id
        case name
        case notifications
    }
}

final class ManagedNotification: NSManagedObject, CoreDataCodable {
    @NSManaged var id: String
    @NSManaged var userNotificationId: String
    @NSManaged var enabled: Bool
    @NSManaged var habit: ManagedHabit
    
    enum CodingKeys: String, CoreDataCodingKey {
        case id
	case userNotificationId
	case enabled
    }
}

…

let encoder = JSONEncoder()
let jsonData = try encoder.encode(object)

I get an error.

The CoreDataEncoder class contains a method

private func encode (_ relationship: NSRelationshipDescription, object: ManagedObject, key: Keys, container: KeyedContainer) throws

that uses NSStringFromClass in its implementation, which always returns nil. This is because you need to use NSClassFromString(“<ModuleName>.<ClassName>”). I checked this and it works.

The same problem is present in the CoreDataDecodable extension in the method

private func set (_ relationship: NSRelationshipDescription, from container: CoreDataKeyedDecodingContainer <Self>, with codingKey: CodingKeys) throws

Please, can you fix this?

It works with my tests if I set current module in the Module setting within the class definition in the model file. I guess you use “global namespace”, aren’t you?. I’ll check if I can find a universal solution.

Yes, I use "Global namespace". Thanks.

I am trying to write a failable tests of your issue but I can't. Could you point me to some sample project so I can check it?

[ns-vasilev]

I could but I need some time.
