A collection of utilities for building Core Data applications in SwiftUI.

🚧 Disclaimer

This library is still very much a WIP as I study some of the new best practices, patterns, and affordances for Core Data after the release of SwiftUI 2.0. Please treat it as a guideline/reference for the time being 🙂.

Features

  • ✅ A CoreDataManager that handles setting up your "Core Data Stack".
  • ✅ A FetchedResultsControlling protocol that helps architect NSFetchedResultsController instances and extract data from their NSFetchRequest results.
  • ✅ Predicate Utilities
  • ✅ Strongly-typed errors for save operations.
  • ✅ NSPersistentStore helpers for using NSSQLiteStoreType in production apps and NSInMemoryStoreType in tests or previews:
