# results

The collection of observation results generated by request processing.

```
var results: [VNObservation]? { get }
```

## Discussion

If the request fails, this property is <doc://com.apple.documentation/documentation/ObjectiveC/nil-227m0>. Otherwise, it contains an array of [`VNObservation`](/documentation/Vision/VNObservation) subclasses specific to the [`VNRequest`](/documentation/Vision/VNRequest) subclass.

Don’t access this property until the request has finished processing.
