SpriteKit SKAction easing

Question

Well the title gives the question away, how can I apply easing to the SKAction node actions in SpriteKit?

I found that this works:

SKAction *moveActi

Apple introduced spring animations in UIKit a couple years ago, by letting you set a spring damping and initial velocity when performing a UIView animation. Unfortunately they didn't implement that in SpriteKit, so I made my own library that does just that.

It's a set of extensions on SKAction that replicate most factory methods, adding the damping and velocity parameters.
