# storageMode

The storage mode for the heaps you create with this descriptor.

## Declaration

```swift
var storageMode: MTLStorageMode { get set }
```

## Discussion

Discussion For devices with Apple silicon, you can create a heap with either the MTLStorageMode.private or the MTLStorageMode.shared storage mode. However, you can only create heaps with private storage on macOS devices without Apple silicon. The resources you allocate from a heap inherit that heap’s storage mode. This property’s default value is MTLStorageMode.private.
