## Declaration

```swift
func SKIndexGetMaximumBytesBeforeFlush(_ inIndex: SKIndex!) -> CFIndex
```

## Discussion

Discussion This function is rarely needed and is likely to be deprecated. Apple recommends using the SKIndexFlush(_:) function along with the default memory size limit for index updates. Refer to the SKIndexSetMaximumBytesBeforeFlush(_:_:) function for more information.
