# mailComposeDelegate

The mail composition view controller’s delegate.

## Declaration

```swift
weak var mailComposeDelegate: (any MFMailComposeViewControllerDelegate)? { get set }
```

## Discussion

Discussion The delegate object is responsible for dismissing the view presented by this view controller at the appropriate time. Therefore, you should always provide a delegate, and that object should implement the methods of the MFMailComposeViewControllerDelegate protocol.
