How do I add a search tab bar in SwiftUI?

To add a search tab bar in SwiftUI, you can use the searchable modifier on your TabView. This is often done by setting a search role on one of your tabs, which allows the search field to take the place of the tab bar when selected. Here's a brief overview of how you can implement this:

Set a Search Role: Assign a search role to one of your tabs. This will configure the tab with a default title, image, and pinned placement, making it always available in the trailing edge of the tab bar.
Use the searchable Modifier: Apply the searchable modifier to your TabView. This will allow the search field to appear when the search tab is selected. On iPad and Mac, the search field will appear centered above your app's browsing suggestions.
Implement Search Suggestions: You can enhance the search experience by adding search suggestions. This can be done by using the searchSuggestions modifier, which allows you to provide a list of suggestions that users can select from.

For a detailed explanation and example, you can refer to the session Build a SwiftUI app with the new design (11:10) from WWDC 2025, which covers crafting search experiences in SwiftUI apps.
