An implementation of DAO pattern for CoreData and Realm. Helps you think less about database in your application.
- Use your persistence layer synchronously for CRUD operations.
- Abstraction of database objects (entries) from application objects (entities).
- Abstraction from concurrency.
Cocoapods
For using with CoreData:
pod 'DAO/CoreData'
Or with Realm:
pod 'DAO/Realm'
// Create DAO instance
let dao = RealmDAO(RLMMessageTranslator())
//...
// Create message entity
let message = Message(entityId: "abc", text: "text")
// Save message to database
try? dao.persist(message)
// Read saved message from database
let savedMessage = dao.read(message.entityId)
// Delete message from database
try? dao.erase(message.entityId)
Please look at the example project for more information.
- If you have big and complex database schema. Many entities, many relationships.
- If you want to use specific features of database. Realm Mobile Platform, for instance is not compatible with DAO implementation.
- If you have thousands of objects (> 10-20K). Performance can be the issue.
