I have created one entity called “Devices”. You can see in the above screenshot.

Import the Core Data framework

For the functionalities of core data we have to import the core data framework.

Lets Save the Data in the Entity

We will get the NSManagedObjectContext reference from the AppDelegate.

NSEntityDescription is used for find the Entity.
NSManagedObject will create new object in the Entity.
save() method is used for save the context.

Get all Data from Entity and Fill the table

NSFetchRequest is used to fetch the data from the Entity.

Sample Code

In the next tutorials I will try to add about the Insert, Update and Delete functionality with the use of Core Data.
Happy Coding 🙂
