Describe the bug

                                   cropRect: v.currentCropRect(),
                                   scrollViewContentOffset: v.assetZoomableView!.contentOffset,
                                   scrollViewZoomScale: v.assetZoomableView!.zoomScale,

Having similar issue where pressing multiple selection button after denying photo library access permission results in a crash

[angelo-RSVP]

I don't know why the sample app isn't showing the multiple button until permission is granted. Is there a configuration for it?

Update: Just hid the button on first launch until permission is checked

public override func viewDidLoad() {
super.viewDidLoad()
. . .
v.assetViewContainer.multipleSelectionButton.isHidden = true
}

This should be fixed with @hansemannn PR. It will be in the next version, hopefully by the end of the week.
