Sho would u please implement Team and History as a core data object? The model structures are already committed, so we only need schemas and handlers.

Sho372 commented 4 years ago

I've implemented Team and History core data object. I merged it to dev. I don't think I understand how to use the core data properly, but it's working anyway.

Note:

Do not do this. Using foreign keys is something that you do in a database. CoreData is not a database.

https://stackoverflow.com/questions/40083934/coredata-swift-3-how-to-join-two-entities (Never mind this note.)

CoreData isn't a Database. It's an object persistence layer. There is no concept of primary keys or foreign keys in CoreData.
