How do I sync Core Data with CloudKit?

Syncing Core Data with CloudKit allows iOS applications to seamlessly store and sync local data with Apple’s iCloud infrastructure. This integration helps in maintaining data consistency across multiple devices. Below is a basic example explaining how to achieve this synchronization.


        // Code example to sync Core Data with CloudKit
        
        import CoreData
        import CloudKit
        
        let container = NSPersistentCloudKitContainer(name: "YourDataModel")
        container.loadPersistentStores(completionHandler: { (storeDescription, error) in
            if let error = error as NSError? {
                fatalError("Unresolved error \(error), \(error.userInfo)")
            }
        })
        
        // Fetch data from Core Data
        let fetchRequest: NSFetchRequest = YourEntity.fetchRequest()
        do {
            let results = try context.fetch(fetchRequest)
            // Process results
        } catch {
            print("Fetch failed")
        }
        
        // Save data to Core Data
        let newItem = YourEntity(context: context)
        newItem.attribute = "New Value"
        
        do {
            try context.save()
        } catch {
            print("Save failed")
        }
        
        // Sync with CloudKit
        let cloudKitContainer = CKContainer.default()
        let privateDatabase = cloudKitContainer.privateCloudDatabase
        
        privateDatabase.fetch(withRecordID: CKRecord.ID(recordName: "yourRecordID")) { record, error in
            if let error = error {
                print("Error fetching record: \(error)")
            } else {
                // Update Core Data with fetched record
                // Your synchronization code here
            }
        }
