I think it's not necessary in this case, but maybe you can use a weakSelf,
as the current code already uses a lot of this:
`CDVContacts* __weak weakSelf = self; // play it safe to avoid retain
cycles`
> Unable to use Cordova Plugins that use a native view directly on pickContacts
> callback.

> Key: CB-10784
> URL: https://issues.apache.org/jira/browse/CB-10784
> Project: Apache Cordova
> Issue Type: Bug
> Components: Plugin Contacts
> Affects Versions: Master
> Environment: iOS
> Reporter: Cory Thompson
> Priority: Minor
> Labels: ios
>
> I attempted to open a native dialog directly after a using pickContacts and
> receive the following error on iOS.
> navigator.contacts.pickContact(onContactItemPickedSuccess,
> onContactItemPickedError);
> function onContactItemPickedSuccess(contact) {
> navigator.notification.confirm(…);
> }
> Warning: Attempt to present <UIAlertController: 0x14a83600> on
> <CDVContactsPicker: 0x151e7400> whose view is not in the window hierarchy!
> A workaround is wrap the confirmation code using a JavaScript setTimeout for
> 1000ms.
> I’ve dug into the Objective C code and what I suspect is happening is that
> the successCallback is called before the animation for closing the
> CDVContactsPicker has finished.
> I’ve tested moving the callback after the close animation and my issue is
> resolved. I will include a pull request in the comments.
> The only potential problem I see with this is the original author may have
> decided to return before animation close so that a user could update the HTML
> behind the contactPicker therefore appearing to load much faster.
