# handleUserActivity(_:)

```

## Parameters

- `userInfo`: The dictionary containing data about the activity.

## Discussion

Discussion Use this method to respond to Handoff–related activity. WatchKit calls this method when your app launches as a result of a Handoff action. Use the information in the provided userInfo dictionary to determine how you want to respond to the action. For example, you might decide to display a specific interface controller. The default implementation of this method does nothing. When overriding this method, don’t call super. note: If you are creating a SwiftUI app for watchOS 7 or later, use the onContinueUserActivity(_:perform:) modifier instead. Handling Activities from Complications and Notifications WatchKit calls this method when your app launches from a complication or notification. Update your app’s user interface based on the userInfo parameter. Your app should seamlessly continue the interaction from the complication or notification. When your app launches because the user tapped on a complication, the userInfo dictionary contains the CLKLaunchedTimelineEntryDateKey key. The value is a Date object that indicates when the complication launched.
