I’d check your return value for this method in your layout:
- (UICollectionViewLayoutAttributes *)layoutAttributesForInteractivelyMovingItemAtIndexPath:(NSIndexPath *)indexPath withTargetPosition:(CGPoint)position NS_AVAILABLE_IOS(9_0);

I followed the directions here,
http://nshint.io/blog/2015/07/16/uicollectionviews-now-have-easy-reordering/
- to add iOS9 style dragging to my UICollectionView - and it sort of works.
As described in the article, I added a long press gesture recognizer and
wired it in to make calls on the collection view -- but now, if I long
press, the element under my finger disappears. As I drag the transparent
image around, the other elements shift - but I can never see the element I
am dragging around. When I let go, there is simply a hole left where I
"dropped" the element.
I do, very much, have a custom layout and I'm not sure that if, for drag, I
need to do anything special. Do I need to calculate the frame of the item I
am dragging around? I'm not sure what to try next except to roll my own
dragging. Any thoughts or things to try?
Thanks in advance.
