# fetchPredicate

The receiver’s fetch predicate.

## Declaration

```swift
var fetchPredicate: NSPredicate? { get set }
```

## Discussion

Discussion The receiver uses predicate when fetching its content, for example in fetch(_:). If you need to customize the fetching behavior further, you can override fetch(with:merge:).
