When your user interacts with a search box, you can help them discover what they could search for by providing **Query suggestions**.

Query suggestions are a specific kind of multi-index interface:

* The main search interface will use a regular <Index />.
* As users type a phrase, suggestions from your [Query Suggestions index](/doc/guides/building-search-ui/ui-and-ux-patterns/query-suggestions/js) are displayed.

These guides walk you through the steps needed to build a Query Suggestions experience with InstantSearch iOS:

* [Build a Query Suggestions UI with InstantSearch iOS and SwiftUI](/doc/guides/building-search-ui/ui-and-ux-patterns/query-suggestions/tutorials/building-query-suggestions-ui/declarative/ios)
* [Build a Query Suggestions UI with InstantSearch iOS and UIKit](/doc/guides/building-search-ui/ui-and-ux-patterns/query-suggestions/tutorials/building-query-suggestions-ui/programatically/ios)
