Using a Core Data Model in Swift Playgrounds

This article explores how to use Core Data models within Swift Playgrounds in Xcode. It builds on a 2015 guide by Jeremiah Jessel, detailing the process of setting up a Core Data stack programmatically. The author investigates using compiled .momd files instead of .xcdatamodeld files, noting limitations like the inability to use NSManagedObject subclasses and the need to re-add updated models. A step-by-step walkthrough covers adding a data model, creating entities and attributes, adding a playground, building the project, locating the .momd file, and dragging it into the playground's Resources folder. Ideal for developers wanting to experiment with Core Data in a lightweight environment.
