In video we look at what CoreData is, how to set it up in an existing project, along with how to Create/Read/Update/Delete a simple Entity.

Any other Core Data topics you'd like covered? Let me know below.

How to sort data in Data Core and then use it in a line chart. Dates on one data axis (Mon-Sun) and miles driven by car on the other, as an example.

@@magnusagnwik9018 Hi Magnus. This is doable but tricky. I don't think the hard part will be the sorting of data (Core Data is really strong here). The hard part is displaying the graph. One way I have seen this done is through Core Graphics. I have an intro to Core Graphics in my Starbucks playlist. You can start there. Let me know how it goes. kzfaq.info/get/bejne/npeTqcx-x9bUlJ8.html

08:29 shouldn't be something like save(employee) ? Seems the arg employee: Employee is not used within the updateEmployee func..

Thanks for such a well-explained tutorial. I have one question regarding Core Data, how to connect it to the server. More specifically, do you have a tutorial where I can see how Core Data communicates with a server and pulls data online from an API and then writes it to Core Data, also to track changes on the server and synchronize them? Of course, it can also work in offline mode. It's very useful and specific, and a little different from this one.

Did you make a video on updating without updating any attributes?

Hi Jonathan, this is by far the most coherent tutorial on CoreData that I've come across. I have a couple of questions - When creating a new application with CoreData checked, the creation of the Persistent container takes place in App Delegate, and Apple recommends passing this container to other View Controllers as needed. Can you tell me the advantages of using the method you've described over that of Apple's recommended? Also, do I need to instantiate the class CoreDataManager anywhere?

@swiftarcade7632 4 жыл бұрын

Hi Calum. Thank you so much! Glad you enjoyed it. The main advantage of knowing how to set these things up from scratch is the ability to add CoreData after a project has already been created. If you are creating something new, by all means use the one Xcode provides. But by knowing how to create from scratch you have a little bit more flexibility in how you integrate CoreData into your project - which some projects need. Hope that helps!

Hi, I'm using Codable to decode json to NSManagedObject, decoding is success, but when save context is called app crashes with message encodeWithCoder:]: unrecognized selector sent to instance
