# init()

Initializes a sequence request handler.

## Declaration

```swift
init()
```

## Discussion

Discussion Unlike the VNImageRequestHandler, this initializer accepts no input because image data and auxiliary parameters may change from frame to frame, and are handled dynamically in the request-handling perform methods.
