i'm trying to save my API response in my core data entity. I have some attributes that have custom classes. These custom classes are from third party library which i cannot make a change. This is my entity which contains custom class attributes, enter image description here
When i try to save the response in my entity like this,
let appDelegate = UIApplication.shared.delegate as? AppDelegate
let context = appDelegate?.persistentContainer.viewContext
let entity = NSEntityDescription.entity(forEntityName: "SingleChatCoreData", in: context!)
let user = NSManagedObject(entity: entity!, insertInto: context)
for items in dateWiseSortedSingleRooms
{
user.setValue(items.name, forKey: "name")
user.setValue(items.actualNameFor_1_2_1_chat, forKey: "actualNameFor_1_2_1_chat")
user.setValue(items.isGroup, forKey: "isGroup")
user.setValue(items.lastMsgRead, forKey: "lastMsgRead")
user.setValue(items.lastMsgTimeActual, forKey: "lastMsgTimeActual")
user.setValue(items.lastMessage, forKey: "lastMessage")
user.setValue(items.lastMsgTime, forKey: "lastMsgTime")
user.setValue(items.profilePic, forKey: "profilePic")
user.setValue(items.roomSID, forKey: "roomSID")
user.setValue(items.isNewGroup, forKey: "isNewGroup")
user.setValue(items.unReadMsgsCount, forKey: "unReadMsgsCount")
user.setValue(items.unReadMsgsCount, forKey: "unReadMsgsCount")
user.setValue(items.members, forKey: "members")
user.setValue(items.messages, forKey: "messages")
user.setValue(items.twChannelObj, forKey: "twChannelObj")
}
do {
try context?.save()
print("Saved successfully.")
} catch {
print("Fail to save")
}
The app crashes with an error message in console,
error: SQLCore dispatchRequest: exception handling request: <NSSQLSaveChangesRequestContext: 0x28389ff20> , -[TCHMember encodeWithCoder:]: unrecognized selector sent to instance 0x2809f75c0 with userInfo of (null)
I have searched for the error and i just to come to result that NSCoding protocol should be used . Then i have used NSCoding protocol in my NSManagedObjecClass for the entity like this,
import CoreData
import TwilioChatClient
@objc(SingleChatCoreData) public class SingleChatCoreData: NSManagedObject,NSCoding {

} Now ,again when i try to save the response it crashes on same point with same error, I'm stuck to this issue more than a week, kindly can anyone let me know why this issue is so what the mistake i'm doing?
