# classForCoder

Overridden by subclasses to substitute a class other than its own during coding.

## Declaration

```swift
var classForCoder: AnyClass { get }
```

## Discussion

Discussion This method is invoked by NSCoder. NSObject‘s implementation returns the receiver’s class. The private subclasses of a class cluster substitute the name of their public superclass when being archived.
