How to use in UIImagePickerController

[StevenSorial]

Trying to add a publisher to UIImagePickerController using a DelegateProxy

My code:

extension UIImagePickerController {
  var didFinishPickingMedia: AnyPublisher<[UIImagePickerController.InfoKey: Any], Never> {
    let didPickSelector =
      #selector(UIImagePickerControllerDelegate.imagePickerController(_:didFinishPickingMediaWithInfo:))

    return delegateProxy
      .interceptSelectorPublisher(didPickSelector)
      .map { $0[1] as! [UIImagePickerController.InfoKey: Any] }
      .eraseToAnyPublisher()
  }

  var didCancel: AnyPublisher<Void, Never> {
    let didCancelSelector = #selector(UIImagePickerControllerDelegate.imagePickerControllerDidCancel(_:))
    return delegateProxy
      .interceptSelectorPublisher(didCancelSelector)
      .map { _ in () }
      .eraseToAnyPublisher()
  }

  private var delegateProxy: UIImagePickerControllerDelegateProxy {
      .createDelegateProxy(for: self)
  }
}

private class UIImagePickerControllerDelegateProxy: DelegateProxy,
                                                    UIImagePickerControllerDelegate,
                                                    UINavigationControllerDelegate,
                                                    DelegateProxyType {
  func setDelegate(to object: UIImagePickerController) {
    object.delegate = self
  }
}

Works well on devices but crashes when presenting the controller on a simulator with 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil'.
