speed
A factor that increases or decreases the animation’s rate of playback.
Declaration
var speed: Float { get set }Discussion
The default value is 1.0, which doesn’t alter the animation’s rate of playback. A value of 2.0 plays the animation at twice the normal rate, and a speed of 0.5 makes the animation finish after twice the normal time. A negative value plays the animation in reverse.
This property doesn’t affect the animation’s delay.
