Core Data with CloudKit: The Basics
At WWDC 2019, Apple brought a major update to Core Data by introducing NSPersistentCloudKitContainer. This means that by using Core Data with CloudKit, users can seamlessly access the data in their application on all their Apple devices without having to write a lot of code.
Core Data provides powerful object graph management functionality for developing applications with structured data. CloudKit allows users to access their data on every device where they have logged into their iCloud account, while also providing a constantly available backup service. Core Data with CloudKit combines the advantages of local persistence, cloud backup, and network distribution.
In 2020 and 2021, Apple continued to enhance Core Data with CloudKit, adding functionality for syncing public databases and shared databases on top of the initial support for private database syncing.
In a series of blog posts, I will introduce the usage, debugging techniques, console settings, and attempt to delve deeper into its syncing mechanism of Core Data with CloudKit.
