# advanceIntervalForDelegateInvocation

Permits advance invocation of the associated delegate, if any.

## Declaration

```swift
var advanceIntervalForDelegateInvocation: TimeInterval { get set }
```

## Discussion

Discussion Use this property specify the number of seconds early to invoke the delegate object. When possible, an AVPlayerItemLegibleOutput uses this value to call its delegate earlier than it would otherwise.
