Get the NSEntityDescription of that object (that's the entity property of the NSManagedObject). And then you can simply iterate on the names (via the attributesByName property) and set all values to nil

for (name, attributes) in entity.attributesByName { setValue(nil, forKey: name) }

You can do the same for the relationships of that object (via the relationshipsByName property)

for (name, relationship) in entity.relationshipsByName { setValue(nil, forKey: name) }

With this methods you can also exclude specific properties (if there are some you don't want to clear).
