Crash in swipeColor function at the very beginning of swiping gesture

[Nadya Post]

Crash occurs at the beginning of swipe gesture - when very slowly start dragging a cell to the right or to the left.

I got the same problem but discovered that it is this code from the example code which introduceg this crash:

cell.defaultColor = tableView.backgroundView?.backgroundColor

The example code should be updated.

In my case the defaultcolor becomes nil and since its being forceunwrapped in SwipyCell it will crash.

SwipyCell {
public var defaultColor: UIColor!
}

The fix is to make sure cell.defaultColor has a real value.
