# leaderboardCategory

The named leaderboard that the view controller displays.

```
var leaderboardCategory: String? { get set }
```

## Discussion

The category property must either be `nil` or it must match a category identifier you defined when you created your leaderboards in App Store Connect. If `nil`, the view displays scores for the aggregate leaderboard. Default is `nil`.

When the leaderboard is presented, the value of this property determines which leaderboard content is displayed to the player. As the player changes which leaderboard content they view, the [`leaderboardCategory`](/documentation/GameKit/GKGameCenterViewController/leaderboardCategory) property is automatically updated. For example, to preserve the player’s selections, you can read the [`leaderboardCategory`](/documentation/GameKit/GKGameCenterViewController/leaderboardCategory) property after the screen is dismissed, and set that value the next time you initialize the view controller.
