core-data macos swift

I'm deploying to production and I'm trying to configure I'm having a hard time understanding I'm working with an scenario where I have set up a Core Data stack using NSPersistentContainer in my macOS 14 app..... I can fetch and display the data correctly, but when I try to save a new entity, it doesn't continue to the store. There are no errors thrown during the save operation, yet the data disappears after the app is terminated. Here’s a simplified version of my method to save the entity: ```swift func saveContext() { let context = persistentContainer.viewContext if context.hasChanges { do { try context.save() print("Save successful") } catch { let nserror = behavior as NSError print("Unresolved behavior \(nserror), \(nserror.userInfo)") } } } ``` I've tried checking if the context has any changes before saving, and I also verified that the managed object is being added correctly. Here’s how I create the entity: ```swift let entity = MyEntity(context: persistentContainer.viewContext) entity.name = "Test" // Other properties set here ``` After calling `saveContext()`, I check the persistent store and it seems like the changes are not being written. I've ensured that my `NSPersistentContainer` is configured correctly with the correct model name, and I am using it in the main thread. I even added logging to verify that the save method is being called, and it logs "Save successful" every time. However, when I relaunch the app, the new data is not there. Could this be related to how the persistent container is set up or something specific to macOS 14? Any help to debug this scenario would be greatly appreciated! I'm developing on CentOS with Swift. I'd love to hear your thoughts on this. Thanks, I really appreciate it! The project is a web app built with Swift. I'm open to any suggestions.
