Creates a hosting view object from the contents of the specified archive.

## Declaration

```swift
@MainActor @preconcurrency required dynamic init?(coder aDecoder: NSCoder)
```

## Discussion

Discussion The default implementation of this method throws an exception. To create your view from an archive, override this method and initialize the superclass using the init(coder:rootView:) method instead.
