Great Swift Drag & Drop tutorial

It's easy. I've only been developing for 3 months and I was able to implement this. I also tried several others and this was the one I could understand.

It's written in Swift and it's practically cut and paste. You add the longPress code to your viewDidLoad and then paste the function into the 'body' of your class. The tutorial will guide you but there's not much more to it.

Quick explanation of the code: This method uses a switch statement to detect whether the longPress just began, changed, or is in default. Different code runs for each case. It takes a snapshot/picture of your long-pressed cell, hides your cell, and moves the snapshot around. When you finished, it unhides your cell and removes the snapshot from the view.

Warning: My one word of caution is that although this drag/drop looks great and works close to perfectly, there does seem to be an issue where it crashes upon dragging the cell below the lowest/bottom cell.
