# ARAppClipCodeAnchor.URLDecodingState.failed

A state that indicates the failure to decode an App Clip Code’s URL.

```
case failed
```

## Discussion

The decoding of an App Clip Code URL fails under these circumstances:

- The full app or App Clip is missing the associated-domains entitlement from its code signature.
- The host of the resource identified by the App Clip Code URL doesn’t vend an Apple App Site Association (AASA) file.
- The AASA file hosted at the App Clip Code URL’s domain lacks the App Clip’s fully-qualified application identifier.
- The App Clip Code is not associated to the App Clip in an App Clip experience in App Store Connect.
