To make spacing work you have to alter both code and storyboard

[sashalondon]

Hi I want to change the spacing in-between images and have found in your sample that I have to do it in both the storyboard options and the code:
/// Readwrite. A float value which indicates the spacing between cells.
@IBInspectable public var interitemSpacing: CGFloat = 40.0

I don't know if its a mistake or its suppose to be like that. Thought I would tell you anyway.
