День томуLearn how to use Core Data for iOS to do local data storage! In this lesson, you'll learn how Core Data works and the basics of how you'll use it in your iOS app.
You'll learn all about the Core Data Persistent Container, Managed Object Context, Entities, Attributes and the Core Data Model.
Please note that working with Core Data isn't a beginner level topic. Make sure you've gone through my 29 Day Beginner Challenge first here:

I was checking several youtube videos and series for learning to work with core data, all of them seemed either to simple or confusing because they jumped to a huge code base really quickly without explaining the core data properly first. Your explanation is perfect and easy to follow. Thanks.

I am making an iOS app that uses the camera to capture a flower image, classifies it using a pre-trained Core ML model, retrieves additional information from Wikipedia using an API request, and updates the UI accordingly. I want to create a core data local database with machine learning capabilities inside it. That's why I am here watching this tutorial. Very nicely explained all the steps. I will re-watch it again to build a better understanding. Thank you, please don't stop making tutorials.

Thank. It helped to refresh the memory very quickly regarding CoreData. Very simple and straightforward, and most importantly without unnecessary water. The only thing I want to add is that there is not enough demonstration of how to bind an array to one object, for example, a contact to which a list of messages is attached, because developers, including beginners, often face this. Thanks for the guide!

Hey Chris, first, I have to say your tutorial is so helpful, thanks for providing so many wonderful videos. Then, I have a question on core data, is that only stored in local machine? could the data be shared with other users? for example, if I try to develop an app there has user login, and can I use core data to store all user info? or I have to let my app connect a real db, sql?

Great tutorial and I have to really appreciate the time and effort that has gone into making this so detailed. I have used CoreData with Obj C some time ago so I wanted to refresh my knowledge and I learned so many new things. I would say one thing I was hoping to see was about the migrations if we need to change the DataModel when shipping a new version of the app - does this still need to be done or has Apple taken made this easier somehow ?
@CodeWithChris 2 роки тому
"Hello, supposedly all the datamodels or the ""set-up"" should be the same accross different versions because its an apple ""core"" database.. however, do remember that this is a local only database,, so if the user decides to change phones then the data won't get carried over, for that it would be ideal to check out cloud solutions like Firebase. - Francis"

This is why I wish Swift worked nicely with C++. I like being able to create my own persistent storage libraries and it’s so much easier and less convoluted in C++ than anything you can do with Swift.

Hello, there might be some 3rd party library/framework that can be used to run or add c++ files on your project, i suggest looking at options in github or cocoapods - Francis

Not often you hear something is "less convoluted" in C++. Usually, it's very much the opposite case. But with CoreData, unfortunately, it retains its reference baggage from ObjectiveC. We need a new SwiftDataStorage framework from Apple, that fundamentally uses value types, with Swift idioms, and a SwiftUI-like API.

Hi chris. It is good explaination in coredata. But In advance I am or most people use SwiftUI not storyboard every more. It is over 2 years since I've seem it again. More codes and confused.... I like the layout in coredata person relation to family. But not storyboard. If I used swiftUI, please show me CRUD in coredata for swiftUI. Look forward to see it Thanks. Toan Nguyen

Soon we will focus more on SwiftUI. We will do both actually as Storyboard is beginner friendly. Meanwhile, I found a couple of interesting tutorials for you on Google, feel free to search for more. www.hackingwithswift.com/books/ios-swiftui/how-to-combine-core-data-and-swiftui www.raywenderlich.com/9335365-core-data-with-swiftui-tutorial-getting-started developer.apple.com/forums/thread/650876 @AdrienVillez

What website or app do you use to get images that you use in your Xcode projects and how do you make the quality of those images differ for different phones???
@CodeWithChris 3 роки тому
You can get images from pixabay.com, unsplash, or icons8.com - Kat

quick question about relationships would it work the same way if our family entity had an attribute of an array of people? and we just put the attribute type set to transformable? and then set the custom class to [Person]

"Hello, yes its possible to make a ""Family"" class with an array of members from a ""Person"" class, just make sure you have created the Person class first - Francis"
