# archiver(_:didEncode:)

Informs the delegate that a given object has been encoded.

```
optional func archiver(_ archiver: NSKeyedArchiver, didEncode object: Any?)
```

## Parameters

`archiver`

The archiver that sent the message.

`object`

The object that has been encoded. `object` may be `nil`.

## Discussion

The delegate might restore some state it had modified previously, or use this opportunity to keep track of the objects that are encoded.

This method is not called for conditional objects until they are actually encoded (if ever).
