# SCNDetailedErrorsKey

Detailed error information from SceneKit’s scene file loading process.

```
let SCNDetailedErrorsKey: String
```

## Discussion

If SceneKit reports an error when creating or loading from a scene source, the <doc://com.apple.documentation/documentation/Foundation/NSError/userInfo> dictionary of the returned <doc://com.apple.documentation/documentation/Foundation/NSError> object may contain this key, whose value is an array of dictionaries (each containing one or more of the keys listed in [Scene File Consistency Error Keys](/documentation/SceneKit/scene-file-consistency-error-keys)) providing details about the location of the error in the scene file.

If you specify <doc://com.apple.documentation/documentation/Swift/true> for the [`checkConsistency`](/documentation/SceneKit/SCNSceneSource/LoadingOption/checkConsistency) option when creating or loading from a scene source, SceneKit verifies the scene file against the specification for its file format. Verifying a scene file can result in additional error reports for violations of the file format specification that do not prevent SceneKit from loading the file.
