Question 1

How do I use PersistenceKit with SwiftUI?

Accepted Answer

Integrate PersistenceKit by creating stores in view models or using @StateObject. Since it's a plain Swift library, wrap stores in ObservableObject to publish changes—for example, use Combine to observe store updates and refresh SwiftUI views accordingly.

Question 2

PersistenceKit vs Core Data: which should I choose?

Accepted Answer

PersistenceKit is better for simple, Codable-based local storage with minimal setup, ideal for preferences or small datasets. Core Data suits complex data models with relationships, migrations, and iCloud sync, but has a steeper learning curve.

Question 3

How to handle errors in PersistenceKit?

Accepted Answer

Use do-try-catch blocks for robust error handling, as methods throw errors. Avoid try! from examples; instead, catch specific errors like storage failures or permission issues and implement fallback logic.

Question 4

Does PersistenceKit encrypt data in file storage?

Accepted Answer

No, FilesStore does not encrypt data by default. For sensitive information, use KeychainStore which relies on Apple's Security Framework. Implement custom encryption for files if needed.

Question 5

Can I use PersistenceKit with Combine for reactive updates?

Accepted Answer

Yes, wrap PersistenceKit stores in custom Publishers or use Combine to observe changes. For instance, create a publisher that emits events when objects are saved or deleted, enabling reactive data flow in your app.
