The concept of a public shared database in SwiftData is not explicitly mentioned in the provided context. However, SwiftData does offer features that could be relevant to shared data scenarios, such as synchronization with CloudKit, custom data stores, and the ability to track model changes over time.
For more detailed information on SwiftData's capabilities, you might want to explore the session titled "What’s new in SwiftData" from WWDC 2024, which covers various aspects of SwiftData, including custom data stores and the history API. You can find more about these topics in the following chapters:
These features could potentially be used to implement a shared database-like functionality, depending on your specific requirements.
