# showNotice(_:)

Posts an event to the system, which displays the information in the system UI.

## Declaration

```swift
final func showNotice(_ event: GroupSessionEvent)
```

## Parameters

- `event`: The event to display in the system UI.

## Discussion

Discussion Call this method to update the system’s UI with information about session-related events. For example, a music-listening app might post an event to notify the group that a participant stopped playback. The system displays the event information only on the current device, and doesn’t forward events to other devices.
