# lastError()

Returns the last error that occurred during evaluation.

## Declaration

```swift
func lastError() -> (any Error)!
```

## Discussion

Discussion Your authorization plug-in should override this method and return the last error that occurred during evaluation or nil if no error occurred. A downstream plug-in can set a context value using the kAuthorizationContextFlagSticky flag to make it available to the SFAuthorizationPluginView class in case of an error.
