To keep the example simple our data model will have one entity with two attributes.
A Person with name and age: Person -name: “Create NSManaged Object Subclass…”.
When the project has Core Data Xcode add a bunch of code to our App Delegate.swift.A piece of that code is the managed Object Context.This is the object that we need to access the data model.This post is part of my collection: Swift 2 – For Beginners.Core Data is a persistence framework provided by Apple.
In this example we will see how to use it in our i OS application.
First we will see how to create our data model and then how to perform the following basic operations: A data model consist of a group of entities.
The concept of entity in Core Data is similar to the concept of table in SQL.
Each entity can have attributes in the same way that a table can have columns.
To create a new entity you need a project with Core Data included.
Then go to your xdatamodel file and click “Add Entity”, “Add Attribute” to configure it.
