Core Data is Apple’s native framework for persisting data that works across all their platforms.
It has a reputation of being hard to use, not performant, and complicated to debug - many people have used other persistence methods such as SQLite or Realm.
But Over the past few years it has improved and continues to improve. A few years ago a method was introduced to more easy create stacks and use multiple threads for performance. At WWDC this year further changes were made to allow some storage in iCloud and also support with diffable data sources.
This will not be a beginner tutorial for Core Data. I propose to cover modern ways of working through best practices: - Setting up data sources, effective fetching of data from stores - Cloud storage, connecting to UITableViews/UICollectionViews through the new diffable data sources. How to bind SwiftUI Views to data.
Many people think that Core Data is unsupported and not a good solution for persistence. I will show how it is still relevant in modern application development and it is still Alive and Kicking.
