# isLastFrame

A Boolean that indicates the last frame in a tracking sequence.

```
var isLastFrame: Bool { get set }
```

## Discussion

If set to <doc://com.apple.documentation/documentation/Swift/true>, the current tracker will be released to the pool of available trackers when the current frame finishes processing.
