Run, Break, Inspect: Explore effective debugging in LLDB

Learn how to use LLDB to explore and debug codebases. We’ll show you how to make the most of crashlogs and backtraces, and how to supercharge breakpoints with actions and complex stop conditions. We’ll also explore how the “p” command and the latest features in Swift 6 can enhance your debugging experience.

What’s new in StoreKit and In-App Purchase

Learn how to build and deliver even better purchase experiences using the App Store In-App Purchase system. We’ll demo new StoreKit views control styles and new APIs to improve your subscription customization, discuss new fields for transaction-level information, and explore new testability in Xcode. We’ll also review an important StoreKit deprecation.

SwiftUI essentials

Join us on a tour of SwiftUI, Apple’s declarative user interface framework. Learn essential concepts for building apps in SwiftUI, like views, state variables, and layout. Discover the breadth of APIs for building fully featured experiences and crafting unique custom components. Whether you’re brand new to SwiftUI or an experienced developer, you’ll learn how to take advantage of what SwiftUI has to offer when building great apps.

Track model changes with SwiftData history

Reveal the history of your model’s changes with SwiftData! Use the history API to understand when data store changes occurred, and learn how to use this information to build features like remote server sync and out-of-process change handing in your app. We’ll also cover how you can build support for the history API into a custom data store.

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”.

Implement App Store Offers

Learn how to engage customers with App Store Offers using App Store Connect, as well as the latest StoreKit features and APIs. Discover how you can set up win-back offers (a new way to re-engage previous subscribers) and generate offer codes for Mac apps. And find out how to test offers in sandbox and Xcode to make sure they work smoothly.

Create a custom data store with SwiftData

Combine the power of SwiftData’s expressive, declarative modeling API with your own persistence backend. Learn how to build a custom data store and explore how to progressively add persistence features in your app. To get the most out of this session, watch “Meet SwiftData” and “Model your schema with SwiftData” from WWDC23.

Demystify SwiftUI containers

Learn about the capabilities of SwiftUI container views and build a mental model for how subviews are managed by their containers. Leverage new APIs to build your own custom containers, create modifiers to customize container content, and give your containers that extra polish that helps your apps stand out.

Platforms State of the Union

Discover the newest advancements on Apple platforms.

Enhance your UI animations and transitions

Explore how to adopt the zoom transition in navigation and presentations to increase the sense of continuity in your app, and learn how to animate UIKit views with SwiftUI animations to make it easier to build animations that feel continuous.
