It seems like you have some concerns about SwiftData. While I can't address subjective opinions, I can provide some insights into what was presented about SwiftData at WWDC 2024.
SwiftData is a framework designed to simplify building your app's model layer and persisting data across app launches. It offers features like schema modeling, migration, graph management, and synchronization with CloudKit. Some of the key updates and features highlighted include:
- Modeling and Persistence: SwiftData allows you to define your schema using Swift language features like macros, making it easy to model and persist data.
- Custom Data Stores: You can now use custom data stores, allowing you to store data using backends like SQLite or a remote web service.
- History API: This feature provides access to the history of changes in a datastore, useful for tracking local changes that need to be synced to a remote service.
- Performance Optimization: New macros and query optimizations have been introduced to improve performance.
For more detailed information, you can check out the session What’s new in SwiftData (00:57) which covers the adoption of SwiftData and its new features.
Platforms State of the Union
Discover the newest advancements on Apple platforms.
What’s new in Swift
Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
Explore the Swift on Server ecosystem
Swift is a great language for writing your server applications, and powers critical services across Apple’s cloud products. We’ll explore tooling, delve into the Swift server package ecosystem, and demonstrate how to interact with databases and add observability to applications.
Consume noncopyable types in Swift
Get started with noncopyable types in Swift. Discover what copying means in Swift, when you might want to use a noncopyable type, and how value ownership lets you state your intentions clearly.

A Swift Tour: Explore Swift’s features and design
Learn the essential features and design philosophy of the Swift programming language. We’ll explore how to model data, handle errors, use protocols, write concurrent code, and more while building up a Swift package that has a library, an HTTP server, and a command line client. Whether you’re just beginning your Swift journey or have been with us from the start, this talk will help you get the most out of the language.
Explore Swift performance
Discover how Swift balances abstraction and performance. Learn what elements of performance to consider and how the Swift optimizer affects them. Explore the different features of Swift and how they’re implemented to further understand the tradeoffs available that can impact performance.
What’s new in SwiftData
SwiftData makes it easy to add persistence to your app with its expressive, declarative API. Learn about refinements to SwiftData, including compound uniqueness constraints, faster queries with #Index, queries in Xcode previews, and rich predicate expressions. Join us to explore how you can use all of these features to express richer models and improve performance in your app. To discover how to build a custom data store or use the history API in SwiftData, watch “Create a custom data store with SwiftData” and “Track model changes with SwiftData history”.
