SwiftUI Data Persistence in 2025: SwiftData, Core Data, AppStorage & SceneStorage Explained (with WWDC 2025 updates)

If you're building iOS apps in 2025 using SwiftUI, you’ve probably asked yourself:

How should I save my data?

Should you use @AppStorage? @SceneStorage? What about SwiftData? Is Core Data still relevant?

To save you from endless guessing (and context loss between WWDC sessions), I’ve written a full breakdown of all your data persistence options in SwiftUI, with working code examples and updated info from WWDC 2025.

👇 Here’s what you’ll learn:

• When to use @AppStorage vs @SceneStorage
• Full CRUD in SwiftData (insert, fetch, update, delete)
• Custom filtering with #Predicate and FetchDescriptor
• WWDC 2025 SwiftData upgrades (model inheritance, Codable filters, persistent history)
• Core Data setup for legacy apps, including the full CRUD workflow in one block
• How to choose the right tool for your use case (cheat sheet included)
