# queryPlayerGroupActivity(_:withCompletionHandler:)

Finds the number of players in a player group who recently requested a match.

```
func queryPlayerGroupActivity(_ playerGroup: Int, withCompletionHandler completionHandler: (@Sendable (Int, (any Error)?) -> Void)? = nil)
```

## Parameters

`playerGroup`

A number that uniquely identifies a subset of players in your game.

`completionHandler`

The block that GameKit calls when it completes the request.

    This block receives the following parameters:

- `activity`: The number of match requests for the player group during the previous 60 seconds.
- `error`: Describes an error if it occurs, or `nil` if the operation completes.

## Discussion

Use this method to update your interface. For example, show players the relative activity in each player group. If one group is less active than others, you might display a warning so players are aware that finding a match in that group may take longer.
