I am using CoreData to insert an array of dictionaries ([[String: Any]]) representing objects into a PersistentStore. When inserting the objects, I get the error The operation couldn’t be completed. (Cocoa error 1605.). The next line printed to the console is:

Error Domain=NSCocoaErrorDomain Code=1605 "(null)" UserInfo={NSValidationErrorKey=date, NSValidationErrorObject=Bot}

I am creating the array of dictionaries from a JSON object that has more keys than the corresponding ManagedObject in CoreData. Can I use NSBatchInsertRequest with keys that aren't in the corresponding ManagedObject?

Here is the code:

let batch: [[String: Any]] = getBatch()
let request = NSBatchInsertRequest(entity: Bot.entity(), objects: batch)
let insertResult = try self?.managedObjectContext.execute(request) as? NSBatchInsertResult
let result = insertResult?.result as? Bool
print(result?.description ?? "")
