# EABluetoothAccessoryPickerCompletion

The completion block for the Bluetooth picker.

```
typealias EABluetoothAccessoryPickerCompletion = ((any Error)?) -> Void
```

## Discussion

You use this block to process results generated by the [`showBluetoothAccessoryPicker(withNameFilter:completion:)`](/documentation/ExternalAccessory/EAAccessoryManager/showBluetoothAccessoryPicker(withNameFilter:completion:)) method. The block receives an <doc://com.apple.documentation/documentation/Foundation/NSError> object as its only parameter. If no error occurred, this parameter is set to `nil`.
