# MTLIOPriority.high

Sets a new input/output command queue’s priority to a high priority.

## Declaration

```swift
case high
```

## Discussion

Discussion Create a command queue with a high priority to load important assets or those your app needs quickly. For example, a game that plays sound effects that match its animations can load its audio assets with low latency with a high priority queue.
