Compositional layout is a concept used in both UIKit and SwiftUI to create flexible and dynamic user interfaces. In the context of UIKit, compositional layout is used to display content in different styles depending on the context, such as using an inset grouped appearance in portrait mode and a split view controller sidebar in landscape mode. This approach allows for dynamic content and background configurations based on the layout style, as seen in the implementation for iOS 17.
In SwiftUI, composition is a fundamental concept that allows for the creation of complex user interfaces by combining different views. SwiftUI supports creating lists and other UI elements using a declarative syntax, which can be composed using APIs like ForEach and view builders. This allows for flexible and dynamic UI construction, enabling developers to easily add and modify content without changing the underlying container implementation.
For more details on compositional layout in UIKit, you can refer to the session What’s new in UIKit (08:53). For SwiftUI, the session Demystify SwiftUI containers (03:07) provides insights into composition in SwiftUI.
