Instance Property


Defines the frequency or stiffness characteristics of the spring.


var frequency: CGFloat { get set }


The default value is 0.0, creating a rigid joint between the spring's two bodies. Setting the frequency to a low value, for example 0.5, creates a spring with slow oscillations that will settle slowly. Setting the frequency to a high value, for example 10.0, creates a stiffer spring with faster and fewer oscillations.

var damping: CGFloat

Defines how the spring’s motion should be damped due to the forces of friction.
