Where Core Data is saving?

Question

I use this code to initialize Core Data:

import Cocoa import CoreData class DataController: NSObject { var persistentContainer: NSPersistentContainer! var context: NSManagedObjectContext! override init() { persistentContainer = NSPersistentContainer(name: "Highlightings") persistentContainer.loadPersistentStores(completionHandler: { (storeDescription, error) in if let error = error as NSError? { fatalError("Unresolved error \(error), \(error.userInfo)") } }) context = persistentContainer.viewContext } }

How can I specify a .sqlite file where Core Data should save data?

You could go back to the older approach without NSPersistentContainer. The old API has not been deprecated.

If you're using NSPersistentContainer, you can change the store location using NSPersistentStoreDescription. Something like

let container = NSPersistentContainer(name: "ContinerName") let storeURL = // Initialize to whatever URL you want let description = NSPersistentStoreDescription(url: storeURL) container.persistentStoreDescriptions = [ description ] container.loadPersistentStores(completionHandler: { (storeDescription, error) in // ... }

With the new approach the .sqlite file is located in ~/Library/Application Support/YOURAPPNAME/
