SwiftUI Basics
SwiftUI is a modern framework for building user interfaces across all Apple platforms. Here are some key concepts from the "SwiftUI essentials" session at WWDC 2024:
-
Declarative Syntax: SwiftUI uses a declarative syntax, meaning you describe what you want the UI to look like, and SwiftUI takes care of rendering it. This approach simplifies UI development by reducing boilerplate code.
-
Compositional Views: Views in SwiftUI are compositional, allowing you to build complex interfaces by combining simpler views. This modular approach makes it easier to manage and update your UI.
-
State-Driven: SwiftUI is state-driven, meaning the UI automatically updates when the underlying data changes. This reduces the need for manual updates and helps prevent bugs related to UI state.
-
Platform Integration: SwiftUI provides platform idiomatic capabilities and integrates with a wide range of SDKs, allowing you to create native apps for any Apple platform with less code.
-
Accessibility: SwiftUI automatically creates accessibility elements, making it easier to build apps that are accessible to all users. This includes support for technologies like VoiceOver and Switch Control.
For more detailed information, you can explore the SwiftUI essentials session, which covers the fundamentals of views and their capabilities.
Relevant Sessions
These sessions provide a comprehensive overview of SwiftUI's capabilities and how to leverage them in your app development.
Catch up on accessibility in SwiftUI
SwiftUI makes it easy to build amazing experiences that are accessible to everyone. We’ll discover how assistive technologies understand and navigate your app through the rich accessibility elements provided by SwiftUI. We’ll also discuss how you can further customize these experiences by providing more information about your app’s content and interactions by using accessibility modifiers.
Get started with HealthKit in visionOS
Discover how to use HealthKit to create experiences that take full advantage of the spatial canvas. Learn the capabilities of HealthKit on the platform, find out how to bring an existing iPadOS app to visionOS, and explore the special considerations governing HealthKit during a Guest User session. You’ll also learn ways to use SwiftUI, Swift Charts, and Swift concurrency to craft innovative experiences with HealthKit.
