Implement a minimum space between cells (enhancement)

[ruiwh0]

Thank you for sharing this great job!

I wonder if it would be difficult to implement a minimum space between cells. Like the WildCard app does:

You can kind of recreate this behavior by playing with the scrollResistanceFactor(or kScrollResistanceFactorDefault if you don't set the UICollectionView by code), the springBehaviour.length, springBehaviour.damping and springBehaviour.frequency.

Ive set resistance to 2000.0f, length to 1.0f, damping to 0.8f and frequency to 1.5f, to get a similar animation.
