# maxCount

The maximum number of managed objects the relationship can reference.

## Declaration

```swift
var maxCount: Int { get set }
```

## Discussion

Discussion If you declare a relationship attribute as optional when defining your entities, the framework only enforces minCount and maxCount when that attribute is not nil. The default value is 0.
