CloudKit

CloudKit is a cloud-based service from Apple that allows apps to store and synchronize data securely across devices via iCloud. It enables apps to save user information—such as documents, settings, or game progress—without needing to manage their own servers. CloudKit handles data storage, syncing, and privacy, ensuring information stays up-to-date and protected, while developers can focus on app features. It’s designed to work seamlessly within Apple's ecosystem, providing a reliable, scalable, and secure infrastructure for app data management.
