In the latest updates presented at WWDC, there are several new features and improvements related to TabView:
-
SwiftUI Enhancements:
- TabView in SwiftUI now has a new type-safe syntax that helps catch common errors at build time. You declare a tab struct with a title, image, and content view, and optionally include a selection value for programmatic selection. This ensures all tabs have the same selection type matching the TabView itself.
- The TabView can now be styled to appear as a sidebar or as a segmented control in the toolbar. This flexibility allows for a more customizable user interface.
-
Customization and Flexibility:
- Users can now customize the TabView experience by reordering and hiding infrequently used options. This is programmatically controllable, allowing developers to provide a more personalized experience.
- The new sidebar adoptable TabView style allows users to switch between a tab bar and a sidebar view, enhancing the flexibility of the app's navigation structure.
