# representedObject

The object whose value is presented in the receiver’s primary view.

## Declaration

```swift
var representedObject: Any? { get set }
```

## Discussion

Discussion This property retains the object you provide to it; it does not copy it. In another words, a view controller has a to-one relationship with its represented object and does not own it as an attribute. The representedObject property is key-value coding and key-value observing compliant. When you use the represented object as the file’s owner of a nib file, you can bind controls to the file’s owner using key paths that start with the string representedObject.
