I'm looking for something similar... right now I came up with something like this:

galleryViewController.landedPageAtIndexCompletion = { index in
            let items = delegate.galleryItems
            let focusedItem = items[index]
            // try to get the image locally if possible, works for the initial image but not after that
            if let image = focusedItem.imageView?.image {
                shareView.image = image
                return
            }
            shareView.image = nil // will be set below
            switch focusedItem.galleryItem {
            case .image(let imageCompletionBlock):
                imageCompletionBlock { image in
                    shareView.image = image // my shareView is a custom view that allows saving the image
                }
            default: return
            }            
        }

This works fine, but the downside is that I'm fetching the image a second time over the network just so I can get access to it for saving purposes. There are probably other ways of getting access to the image w/o fetching it twice but this works for now. I may add some image caching into my code that handles the actual request to avoid fetching extra data.
