# availableSources

An array of available timecode synchronization sources that can be used by the timecode generator.

```
var availableSources: [AVCaptureTimecode.Source] { get }
```

## Return Value

A read-only array of [`AVCaptureTimecode.Source`](/documentation/AVFoundation/AVCaptureTimecode/Source) objects representing the available timecode synchronization sources.

## Discussion

This property provides a list of [`AVCaptureTimecode.Source`](/documentation/AVFoundation/AVCaptureTimecode/Source) objects representing the available timecode sources with which the generator can synchronize. The sources may include built-in options such as the frame counter and real-time clock, as well as dynamically detected sources such as connected MIDI or HID devices.

This array is key-value observable, allowing you to monitor changes in real-time. For example, when a new MIDI device is connected, the array is updated to include the corresponding timecode source.
