I create a new process for the drag n drop to swap Cell.
it's working but I would like to create a background at the initial Cell after moving it, instead of blank cell. Thanx for your response
CollectionView cell swapping after longPressure
To be sure I understand.
- Initially, "Rasperry PI en entreprise" was on the right.
- You drag to the left
- You want to see some background at the former place of the dragged cell
Exact ?
id you try changing the background color of this cell at start of dragging, in isSelected (you may have to subclass UICollectionViewCell) ?

- See details here: https://stackoverflow.com/questions/66884805/change-background-and-label-colour-of-uicollectionview-cell-when-it-is-selected
- This should let you not only change color but draw anytghing you want as background
Or simpler, why not change background of all cells. The only visible one will be the one that is moving.
