As an experienced iOS developer who has never worked with Core Data (is that even possible), these 5 videos was an absolute life saver. Great explanation to the basics, and overall great pace. Will definitely come back for more tuts.

If your app isn’t going to add customized code to your managed objects, Xcode automatically generates managed object subclasses that can be used in your code. You should only need to manually subclass entities that need custom behavior.

[@nikhilmuskur7722]

Hi Chris, Just want to clear my confusion SQL -> allows for Create, Delete, Update operations directly Core Data -> Just put's a Persistent Layer Container over the whole SQL thing, where the CRUD operations are done via objects instead of manipulating the data directly Is the above correct interpretation ?

[@CodeWithChris]

Hello, technically yes its like theres a middle man that manages the flow of data, theres no direct connection so you don't know how the actual tables/database is structure which usually makes it safer - Francis

[@sinntechnologies6285]

I understood but coming from using entity framework in asp.net and room from the android side. So more or less have some experience with this type of framework.

[@CodeWithChris]

Hello.yes CoreData is local storage only and there should be plenty similar local storage solutions as well. It can even be as simple as UserDefaults - Francis

[@marcoleder]

Hi chris - short question: how much "skill / practise" do you think is required to do the following (easy, medium, hard): Create an app for IpadOS which always runs in the background and checks battery status all say 15min and sends notification to the user if battery has a certain status? Please let me know Best regards Marco Leder

[@CodeWithChris]

Hello, that would probably be medium-hard teritory because of the state of listening in the background, adding notification, and reading device status - Francis

[@marcoleder]

CodeWithChris Thank you for the quick answer! Well I hope that one day I will get there (got some spare time at the moment), so I'll see what I can do. Thing is, that on my ipad this is something that really sucks because I use it as my main computer now but I do not get any battery notification whatsoever when dropping under 20% or having charged to 80%...

What I got from this video sounds a lot like using JSON in Java, but more like Apple. Just sounds like you gotta serialize, deserialize and use the GUI functions to generate stuff.

[@CodeWithChris]

Thanks for sharing your insights, Kevin! :-) -Arthur

[@toanuk]

Hi Chris. It is very good basic lesson. I would like to you How many records can core data stores. Example family and person Each person can have many records, names, gender, height etc. What is an easier way to use Json or core data. I have basic knowledge in core data, not json. Look forward to your response. Thanks Chris. Toan Nguyen

[@CodeWithChris]

Hello, core data has no "limit" but it takes up storage space in the system so its as big as the internal memory, text data is small though so it will take a lot for it to take a significant amount of memory. JSON can also be stored in storage but it can also be saved in the cloud or a server so it might be more advantageous, it all depends on what app you are making if its online/offline and if its important to save to a server/cloud - Francis
