I really appreciated how you stuck to Core Data and didn't get lost in the UI of everything. This got me started in a great way. Thank you!

[@CodeWithChris]

Core Data is a tough cookie to get at first, glad we were able to help! @AdrienVillez

[@SejutiSharminMethila]

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.

[@CodeWithChris]

We're happy that our content gives value to you. We wish you all the best on the project you're working @SejutiSharminMethila! Happy Coding! --Joash

Glad to hear that! - Kat

[@konstantin215]

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!

[@CodeWithChris]

Thanks for the feedback! - Kat

[@s.mohammadmousavi4684]

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.

[@shawnfrank5303]

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]

"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"

How to start ? Knowing the basics to stater to advance. Do you have something as a step by step process tell advance and tell I am able to launch my app ??? Please advice

[@CodeWithChris]

Hey there, you've come to the right channel. Start with this Beginner playlist bit.ly/BeginnersPlaylist - Kat

[@SteveGoodwinAuthor]

The advice regard using and INT64 is incorrect. An INT64 will take up 4 times the disk space, 4 times the bandwith etc over an INT16. An INT 16 will also only take up 2 bytes of memorys, while and INT 64 will take 8 bytes. The achritecture of the chip doesn't reflect the storage requirement of the object. Hence why an 8 bit image only takes up x, a 16 bit image takes up x, a 24 bit image takes up x etc.

This has to use a formula to calculate grades depending on whether there is a win, draw or loss. I would like it so that I can have a Public database with the data of games played and supply code in the app to calculate a new grade and also possible to have a graph to show the progress of the grade of a player with each game played.

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.

[@CodeWithChris]

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

[@w0mblemania]

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.

[@kasunjayasekara3052]

Thank you very much this is an excellent explanation :). Is that any difference between SwfitUI core data and this tutorial?
