Core Data Tutorial - Lesson 3: CRUD - Create, Retrieve, Update, and Delete

Learn how easy it is to create, retrieve, update and delete from your Core Data database! In this lesson, I’ve pre-built the user interface and we’ll fill in the Core Data code to make the whole app work.

This not only the best Core Data tutorial out there but the best tutorial I've watched in my beginner career. It made me feel I am actually starting to understand coding! I am graduating from a 2-year programming course now and I love iOS development. Thanks a lot!

[RahulYadav-tiqi]

Your Core Data series is so much helpful and understandable. Thank you Chris

[yeserguitar]

Your Core Data series were the best among I watched. Thank you so much Chris!

[ashishnimbria]

Thank you so much Chris. You explain the things in a very easy way. great job bro. :) :)

[cruiseqe]

Chris, you make it look so simple. I thought that it would be much harder. Apart from what you are going to show us next time (filtering & sorting), the only issue remaining is what happens when you have two tables/entities joined together.

[LexoneRUS]

Thank you Chris! Your lessons is a gift for me! Everything is clear and straightforward! There are no usefull information about ios dev in russian.. Best regards.

[arcerc]

The best Core Data tutorial by far. Thank you so much.

[jmd]

I saw many vidéos on coredata on youtube, and i never understand, but this Time, i understood all, it’s well explain even for a french guy 👌, well done 😊

[shubham]

Thanks Chris, you made core data very simple.

[youtubechannel-qxkj]

core data was a headache before i get your series on it, thanks man

[guhanboopathi]

One of the finest videos for core data

[mohamednidhalmrad]

thank you so much it's more easier than I expect

[narenkumar]

I feel after seen your videos, it’s easy for me 👍🏻

[ahmedelawady]

Thanks Chris for the op content, you really have the easiest way to explain.
Is there a resource to handle multiple views in segmentControl

[dashapalshau]

This tutorial is so helpful, I finally managed to understand core data much better. I have a question though about where should I keep all core data related methods, such as fetch, save and delete? Is it more appropriate to put them in controller, or somewhere in the model layer?

[pawelpow]

At the beginning I thought Core data is going to be very easy but as I dived in it was the first actual challenge I faced while using SwiftUI, and I thought It was too hard, but that obviously isn’t true. So I’d say I’m in the middle, I underestimated it before and then I over complicated it whilst trying to learn it but then I stumbled across yours and Swiftful thinking videos.

[LebenWerden]

Hello CodeWithChris, thank you very much much for your CoreData videos. In the beginning CoreData is a big challange. But you did a good job.

You already have a video how to copy or rename Xcode projects?

[syedaurangzaib]

Hello, I really enjoy your way of teaching and your explanation style is also admirable :) core concepts are more clear after watching these videos :)
I have one question how can we add object in core data and specific index, like now on adding new item it append item which appears at the end of the list.
Thanks in advance :)

[batuhanipci]

First off, thank you for these tutorials really helpful!
As side note, just particularly for this sample project I wanted to mention, at 13:30 instead of calling the fetchPeople function and do the fetch I would do something like this to create the user;
self.items?.append(newPerson)
DispatchQueue.main.async {
self.tableView.insertRows(at: [IndexPath(row: (self.items!.count - 1), section: 0)], with:
}
This is only because every time you call the fetch we are fetching entire data just for single insertion in the Core data. Hence it may not be so efficient in performance. Of course it would be different scenario if we needed more data to save.

Thanks, Chris for this wonderful video and simplifying things for us. I wanted to know how you inserted "Ted" initially in core data when the application was built. I tried doing that by using the same insert code in viewDidLoad but it's not working. 🤔🙁
