I have the following code that executes without error. The problem is it only saves the last entry ("Jack Daniels", 3). How do change this so it will save all three entries?

```
let employees = NSEntityDescription.insertNewObjectForEntityForName("Employees", inManagedObjectContext: managedObject)

employees.setValue("John Doe", forKey: "employeename")
employees.setValue(1, forKey: "id")
employees.setValue("Jane Doe", forKey: "employeename")
employees.setValue(2, forKey: "id")
employees.setValue("Jack Daniels", forKey: "employeename")
employees.setValue(3, forKey: "id")

do {
    try managedObject.save()
} catch {
    print("problem saving")
}

```
