Answer 2

Drag from collectionView2:

• Create an independent and drag-able instance of the cell with the same data and place it above the cell to drag
• In Collectionview2, set the cell.isHidden = yes. This way the cell is not visible, but its empty space remains.
• When the drag-able cell is significant dragged away from the original position, remove the original cell from the collectionView animated.

Drag to collectionView1:

When the drag-able cell is above collectionView1 and is dropped:

• insert (animated) a cell to the target position in collectionView1 and set it hidden
• move drag-able cell above the inserted (but hidden) cell
• set target cell to isHidden = false
• remove drag-able cell from superview
