# availableMetadataObjectTypes

An array of strings identifying the types of metadata objects that can be captured.

```
var availableMetadataObjectTypes: [AVMetadataObject.ObjectType] { get }
```

## Discussion

Each string in the array corresponds to a possible value in the [`type`](/documentation/AVFoundation/AVMetadataObject/type) property of the [`AVMetadataObject`](/documentation/AVFoundation/AVMetadataObject) objects reported by the receiver. The available types are dependent on the capabilities of the [`AVCaptureInput.Port`](/documentation/AVFoundation/AVCaptureInput/Port) to which the receiver’s connection is attached.
