# error

An error in the top-level encode.

## Declaration

```swift
var error: (any Error)? { get }
```

## Discussion

Discussion The meaning of this property depends on the setting of the decodingFailurePolicy property. For NSCoder.DecodingFailurePolicy.raiseException, this property is always nil. For NSCoder.DecodingFailurePolicy.setErrorAndReturn, a non-nil value represents the first error encountered while decoding the archive.
