# trafficClass

A traffic class that routes traffic through this network slice.

## Declaration

```swift
let trafficClass: CTSlicingManager.TrafficClass?
```

## Discussion

Discussion The traffic class indicates the quality of service characteristics for the slice, such as voice, video, or background data. When the network slice doesn’t have a specific traffic class restriction, this property returns CTSlicingManager.TrafficClass.any, indicating the slice can handle all types of network traffic.
