Question 1

How do I set up CloudCore for offline sync with Core Data?

Accepted Answer

Enable NSPersistentHistoryTracking in your Core Data stack and add required service attributes like privateRecordData and recordName to each entity, then configure CloudCore in AppDelegate to handle push notifications and background tasks, as per the quick start steps.

Question 2

Does CloudCore support CloudKit sharing and how does it work?

Accepted Answer

Yes, it has built-in CloudKit Sharing support with native UI integration. You need to add CKSharingSupported to info.plist, implement delegate methods for accepting shares, and use CloudCoreSharingController, as detailed in the CloudKit Sharing section.

Question 3

CloudCore vs NSPersistentCloudKitContainer: which is better for my app?

Accepted Answer

Choose CloudCore for field-level sync, explicit CloudKit metadata, and fine-grained control via maskable attributes. Opt for NSPersistentCloudKitContainer if you need simple, record-level sync with minimal setup, as it's Apple's native but less flexible solution.

Question 4

How to handle large media files like videos with CloudCore?

Accepted Answer

Use cacheable assets by conforming entities to the CloudCoreCacheable protocol, which triggers long-lived operations for upload and download, allowing on-demand access and avoiding sync delays, as explained in the Cacheable Assets section.

Question 5

What are common CloudCore errors and how to troubleshoot them?

Accepted Answer

CloudCore automatically manages CloudKit errors like userDeletedZone and changeTokenExpired. For setup issues, ensure all required attributes are correctly mapped and check the example app for implementation details, as troubleshooting is limited in documentation.

Question 6

Can I use CloudCore with an existing Core Data model without breaking it?

Accepted Answer

Yes, but it requires modifying your schema to include service attributes and UserInfo entries, which might involve significant changes and careful testing to maintain data integrity, as highlighted in the service attributes and mapping sections.
