CoreData Batch request error in a Swift program

Question

I'm getting a failure trying to perform a batch delete, and I cannot figure what is happening.

I call the request:

self.deleteAllRecords(entity: self.someEntity)

and the function is:

func deleteAllRecords( entity : String)
    {
        let delegate = UIApplication.shared.delegate as! AppDelegate
        let context = delegate.persistentContainer.viewContext

        
        let fetch = NSFetchRequest<NSFetchRequestResult>(entityName: entity)
        let request = NSBatchDeleteRequest(fetchRequest: fetch)
        
        do {
            let result = try context.execute(request)
            print("result: ", result)
        }
        catch {
             print ("There was an error 1")
        }
        do {
            try context.save()
        } catch {
            print ("There was an error 2")
            }

    }

I'm getting hung up at error 1. What can I try to resolve this?

Answer 1

Seam3 does not currently support the NSBatchDeleteRequest operation, so an invalidOperation error is thrown.
