# DDError.Code

Codes that identify errors that can occur during the framework’s use.

```
enum Code
```

## Overview

The system returns one of these codes to describe a completed operation by invoking a [`DDErrorHandler`](/documentation/DeviceDiscoveryExtension/DDErrorHandler) that the client provides.

## Topics

### Errors

[`case success`](/documentation/DeviceDiscoveryExtension/DDError/Code/success)

An error that indicates an operation succeeds.

[`case unknown`](/documentation/DeviceDiscoveryExtension/DDError/Code/unknown)

An error that indicates an uncategorized problem.

[`case badParameter`](/documentation/DeviceDiscoveryExtension/DDError/Code/badParameter)

An error that indicates the framework doesn’t support a parameter that the extension provides.

[`case unsupported`](/documentation/DeviceDiscoveryExtension/DDError/Code/unsupported)

An error that indicates an unsupported configuration.

[`case timeout`](/documentation/DeviceDiscoveryExtension/DDError/Code/timeout)

An error that indicates a timeout occurs.

[`case `internal``](/documentation/DeviceDiscoveryExtension/DDError/Code/internal)

An error that indicates a problem of internal origin.

[`case missingEntitlement`](/documentation/DeviceDiscoveryExtension/DDError/Code/missingEntitlement)

An error that indicates that the app extension lacks a required entitlement.

[`case permission`](/documentation/DeviceDiscoveryExtension/DDError/Code/permission)

An error that indicates the app extension lacks necessary permissions.

[`case next`](/documentation/DeviceDiscoveryExtension/DDError/Code/next)

An error the framework reserves for future use.
