High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I index app content for Spotlight search using CSSearchableItem?▼

Index app content for Spotlight by creating CSSearchableItem objects with domain and item attributes, then adding them to CSSearchableIndex. This enables iOS and macOS system-wide Spotlight search to locate and display your app's documents, notes, or data.

How does NSUserActivity work for Handoff and Spotlight suggestions?▼

NSUserActivity enables Handoff and Spotlight suggestions by tracking user actions with properties like isEligibleForHandoff and isEligibleForSearch. It syncs user activities across devices and surfaces relevant actions as predictions in Spotlight search results.

Can I integrate App Intents with Core Spotlight indexing?▼

Yes, you can integrate App Intents with Core Spotlight by using the appEntityIdentifier. This provides seamless discoverability, allowing indexed content to connect with App Intents for Siri predictions and Spotlight suggestions.

What's the best way to make app data searchable and sync activities across iOS and macOS?▼

The best way to make data searchable and sync activities is combining Core Spotlight and NSUserActivity. Use CSSearchableItem for indexing data and set NSUserActivity properties like isEligibleForPrediction to enable cross-device syncing and proactive suggestions.

Do I need NSUserActivity if I already use CSSearchableItem for indexing documents?▼

Yes, you need NSUserActivity alongside CSSearchableItem to enable full functionality. While CSSearchableItem indexes documents for Spotlight search, NSUserActivity is required for Handoff, predictive suggestions, and syncing the current screen state across devices.
