# managedObjectContext

The document’s managed object context.

## Declaration

```swift
var managedObjectContext: NSManagedObjectContext { get }
```

## Discussion

Discussion The document automatically creates a managed object context using its persistent store coordinator. Special considerations You must not use the document’s managed object context in writeAdditionalContent(_:to:originalContentsURL:), or any of the asynchronous UIDocument methods.
