## Topics

### visionOS

visionOS is a brand new platform that allows you to build immersive apps and games for spatial computing that run on Apple Vision Pro. Create new apps using SwiftUI to take full advantage of the spectrum of immersion available in visionOS. If you have an existing iPad or iPhone app, add the visionOS destination to your app’s target to gain access to the standard system appearance, and add platform-specific features to create a compelling experience.

### SwiftData

Use SwiftData with SwiftUI to create a seamless connection from your data model to user interface. Like SwiftUI, SwiftData focuses entirely on code, with no external file formats to manage. Instead, it uses Swift’s new macro system to offer a streamlined API. SwiftData uses the `Codable` protocol to understand structures and enumerations, so you can model your data with the tools you already know. These types are fully modeled in the underlying data store, enabling you to perform fast and efficient queries, even on complex structured data.

### Widgets, Live Activities, and watchOS complications

Bring your widgets to new places like the macOS desktop, Standby, and the Lock Screen on iPad. And now many of your widgets also gain new interactive abilities using `Button` and `Toggle`. Support Live Activities to keep users updated with the latest data from your app. Add animations in your widget to respond to user action or data changes.

### SwiftUI

Use the ever-expanding SwiftUI API in your apps, with greater control over scroll and focus behavior, and more. Build sophisticated animations with advanced new capabilities, and even automatically match the speed of your animation to the velocity of user gestures. Share more SwiftUI code with your watchOS app using new `TabView`, `ToolbarItem`, and `NavigationSplitView`. And use `@Observable` with SwiftUI to automatically detect and update only the fields of your views that people access.

### Xcode and developer tools

With the latest Xcode release, you can verify the origin of the frameworks your app depends upon, and add metadata to your own frameworks to ensure other developers about your privacy policies. Learn to install and use on-demand simulators. Enhance your Xcode Cloud build workflows to automate packaging up your app for distribution. And the new strings catalog feature right within Xcode gives even more control over how your UI text is handled in locales around the globe.
