This is the second article for our Core Data series. Previously, we gave you a brief introduction of Core Data and created a simple app to store all your device information. However, we only showed you how to insert records into data store through Core Data API and left out the update & delete operations.
In this tutorial, we’ll continue to work on the app and focus on the following areas of Core Data:
- Updating or deleting an object using Core Data API
- Viewing the raw SQL statement for debugging purpose
