Drag a cell between different types of collection

Question

I have several types of viewing on one screen

In Collection One, I have a normal cell, such as Square. In collectionView two, I have a group cell, for example, the same cell, but several are surrounded by the group border

I need to enable drag and drop between one collection to another.

I am using swift 3.0.

Answer 1

Drag from the View2 collection:

• Create an independent and draggable instance of the cell with the same data and place it above the cell to drag
• In Collectionview2 set cell.isHidden = yes . Thus, the cell is not visible, but its empty space remains.
• When the draggable cell is draggable from its original position, remove the original cell from the CollectionView animated set.

Drag into collectionView1:

When the drag cell is above the View1 collection and discarded:

• insert (animate) the cell to the target position in the View1 collection and set it hidden.
• move the draggable cell over the inserted (but hidden) cell
• set the target cell to isHidden = false
• remove cell with drag and drop from supervisor
