pattern for swiftui

SwiftUI follows several key patterns that make it a powerful framework for building user interfaces across Apple platforms. Here are some of the main patterns highlighted in the SwiftUI essentials session:

1. Declarative Syntax: SwiftUI uses a declarative approach, where you describe what the UI should look like and the framework takes care of rendering it. This is in contrast to imperative UI frameworks where you have to specify how to achieve the desired UI.

2. Composition: SwiftUI encourages breaking down the UI into small, reusable components. This is achieved through view composition, where complex interfaces are built by combining simpler views.

3. State-Driven: SwiftUI views are driven by state. When the state changes, SwiftUI automatically updates the UI to reflect those changes, reducing the need for manual updates and minimizing bugs.

4. Adaptivity: SwiftUI views are adaptive, meaning they can automatically adjust to different styles and contexts. For example, buttons and toggles adapt their appearance based on the context they are used in, such as in menus or forms.

5. Cross-Platform Capabilities: SwiftUI is designed to work across all Apple platforms, allowing developers to share code and create consistent experiences on iOS, macOS, watchOS, and tvOS.

These patterns make SwiftUI a flexible and efficient framework for building modern applications. If you want to explore more about these patterns, you can check the SwiftUI essentials session from WWDC 2024.
