# defaultTileGroup

The tile set’s default tile group.

## Declaration

```swift
var defaultTileGroup: SKTileGroup? { get set }
```

## Discussion

Discussion With auto-mapping enabled, it is possible for some tiles to be removed because there is either no valid rule or a missing tile group for the required adjacency rule. In this situation, those tiles are replaced by the tile group specified by defaultTileGroup.
