# uuid

A unique identifier for the timecode source.

## Declaration

```swift
var uuid: UUID { get }
```

## Discussion

Discussion The UUID uniquely identifies this timecode source. It is particularly useful when multiple sources of the same type are available, allowing your application to distinguish between them. note: This value does not persist across application sessions.
