EasyCoreData

• Helps you quickly assemble CoreData stack

• Provides a generic wrapper around NSFetchedResultsController

Installation:

Swift Package Manager

If you want to use EasyCoreData in any other project that uses SwiftPM, add the package as a dependency in Package.swift:

dependencies: [
  .package(url: "https://github.com/Anastasia-Petrova/EasyCoreData.git", from: "0.2.0"),
]

Example of Usage:

1. Initialize CoreDataController specialized with PersonManagedObject and decoded into PersonViewModel:

   let coreDataController = CoreDataController<PersonManagedObject, PersonViewModel>(
   	entityName: PersonManagedObject.firstName, 
   	keyForSort: PersonManagedObject.firstName, 
   	sectionKey: PersonManagedObject.lastName
   )

2. Set update callbacks:

   coreDataController.beginUpdate = {
       tableView.beginUpdates()
   }
   coreDataController.endUpdate = {
       tableView.endUpdates()
   }

3. Set change callback:

   coreDataController.changeCallback = { change in
       switch change.type {
       case let .row(rowChangeType):
           switch rowChangeType {
           case let .delete(indexPath):
               tableView.deleteRows(at: [indexPath], with: .automatic)
           case let .insert(indexPath):
               tableView.insertRows(at: [indexPath], with: .automatic)
           case let .move(fromIndexPath, toIndexPath):
               tableView.deleteRows(at: [fromIndexPath], with: .automatic)
               tableView.insertRows(at: [toIndexPath], with: .automatic)
           case let .update(indexPath):
               tableView.reloadRows(at: [indexPath], with: .automatic)
           case let .error(error):
               print(error)
           }
       case let .section(sectionChangeType):
           switch sectionChangeType {
           case let .delete(index):
               tableView.deleteSections(IndexSet(integer: index), with: .automatic)
           case let .insert(index):
               tableView.insertSections(IndexSet(integer: index), with: .automatic)
           case let .error(error):
               print(error)
           }
       }
   }

   To Do:

• Implement generic CoreDataController that wraps NSFetchedResultsController
• Implement CoreDataStack that assembles stack
• Unit Test CoreDataController
• Unit Test CoreDataStack
