But for those who do not want to start from the very beginning, you can download this Xcode project to continue to work on the below tutorial.In the last tutorial, we already discussed how to fetch and save a managed object using Core Data API.Following the removal of the object from database, we also remove the record from the table view.Now, let’s run the app and try to remove a record from database.

However, for those with database background, you may want to know the exact SQLs executed behind the scene.

The context provides a method called “delete Object” that allows you to delete the specific object from database.

Note: If this is the first time you learn about Core Data, we recommend you to read the first tutorial.
