Elegant Concurrency Operations in Core Data

Fatbobman:

This article aims to explore how to introduce elegant and safe concurrency operations similar to those of SwiftData into Core Data, implementing a Core Data version of @ModelActor.

Following the fundamental principles of Core Data concurrency operations, all operations on managed objects must be performed on the thread of their owning context. This restriction means that the Actor model cannot be directly applied to Core Data’s concurrent operations.

However, the Swift community proposed the concept of custom Actor executors through SE-392, and this functionality was implemented in Swift 5.9.
