SpotlightSearchTool.SearchReply.StageToken

struct · iOS 27.0+ · SDK 27.1

struct StageToken

An opaque type you use to identify a single pipeline stage within the Spotlight search tool. Within a single call to the Spotlight search tool’s <doc://com.apple.documentation/documentation/foundationmodels/tool/call(arguments:)> method, the tool can run one or more pipeline stages to deliver the requested results. Each stage corresponds to a specific task needed to generate the results. For example, one stage might rank the search results based on their relevance. When delivering results to your app, the tool includes a `StageToken` value in the ``SearchReply`` structure it delivers. You can use the token to associate that data with a particular processing stage of the tool.
