# AVCaptureOutput.DataDroppedReason.discontinuity

The system dropped data because the device providing data experienced a discontinuity, and the output lost an unknown number of data objects.

## Declaration

```swift
case discontinuity
```

## Discussion

Discussion A discontinuity is a situation where the capture system can’t ensure that minimal time passes between the capture of data buffers. This kind of situation can arise when the system as a whole is too busy to handle the data.
