# canBeginTrimming

A Boolean value that indicates whether the current media supports trimming.

```
var canBeginTrimming: Bool { get }
```

## Discussion

Not all media supports trimming. For example, this property returns `false` for HTTP Live Streaming media or protected content.

Observe this property to determine when to change the enabled state of your app UI that initiates trimming.
