# MTLPurgeableState.keepCurrent

The current state is queried but doesn’t change.

## Declaration

```swift
case keepCurrent
```

## Discussion

Discussion The setPurgeableState(_:) method never returns this value. When this value is passed to that function, it returns the current purgability state without changing it.
