Cannot get Flow Layout working under iOS 8

[fruitcoder]

I tried to use your DraggableCollectionView for one of my projects, where we wanted to implement an item reorder feature. Your demo looks amazing, the live-reordering of cells and the automatic scrolling at the edges. Unfortunately, I cannot get it to work in my project. I refactored the Storyboard/Code to use the same structure as in your FlowLayout example. A VC with a CollectionView, conforming to the UICollectionViewDataSource_Draggable protocol (and implementing canMove and moveItem...) and the datasource and delegate of the CV are also set in the storyboard. The layout of the CV is set to the DraggableCollectionViewLayout. But nothing happens when I longPress on a cell. Did I miss something? Is it an issue on iOS 8?
Thank you so much for the amazing work
