Tigorn / DAO

DAO

An implementation of DAO pattern for CoreData and Realm. Helps you think less about database in your application.

Features

• Use your persistence layer synchronously for CRUD operations.
• Abstraction of database objects (entries) from application objects (entities).
• Abstraction from concurrency.

Install

Cocoapods

For using with CoreData:

pod 'DAO/CoreData'

Or with Realm:

pod 'DAO/Realm'

Usage

// 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.

When not recommended to use

• 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.

Requirements

• XCode 9
• Swift 4
• iOS 9
