To explore best practices in SwiftUI, we can refer to the session titled "SwiftUI essentials" from WWDC 2024. Here are some key points discussed in the session:
-
Declarative Syntax: SwiftUI uses a declarative syntax, which means you describe what the UI should look like, and SwiftUI takes care of rendering it. This approach helps in reducing boilerplate code and potential update bugs.
-
State-Driven Views: SwiftUI views are state-driven. When the state changes, SwiftUI automatically updates the UI. This is achieved by maintaining a representation of the UI behind the scenes and updating it as data changes.
-
Composition: SwiftUI encourages breaking down views into smaller, reusable components. This compositional approach does not hurt performance and allows for better code organization.
-
Adaptive Views: Many SwiftUI views and modifiers are adaptive, meaning they can change behavior based on context. For example, the
searchable
modifier can be used to make a view searchable, and SwiftUI handles the details. -
Cross-Platform Capabilities: SwiftUI provides a common set of components across Apple platforms, but also offers specialized APIs for each platform. This allows developers to create apps that feel native to each platform while sharing a significant amount of code.
For more detailed insights, you can refer to the session SwiftUI essentials (01:34) which covers the fundamentals of views in SwiftUI.
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.
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.
Migrate your TVML app to SwiftUI
SwiftUI helps you build great apps on all Apple platforms and is the preferred toolkit for bringing your content into the living room with tvOS 18. Learn how to use SwiftUI to create familiar layouts and controls from TVMLKit, and get tips and best practices.
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.
