CAKeyframeAnimation - move along path and use easing

Question

Is it possible to use CAKeyframeAnimation to move something along a path and at the same time use some sort of easing so there is acceleration or deceleration? I know there is timingFunctions and keyTimes, but I don't see how they would work if you are simply moving along a path.

Something like

anim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut]

?

Or swift 5:

anim.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)

I should have looked. Only saw timingFunctions as a property on CAKeyframeAnimation. Didn't think to look if there was a single property on CABAsicAnimation. Thanks. – Brian May 03 '11 at 12:20
I looked and some of the docs explicitly say this value is ignored for keyframe animations. Those docs are wrong; this works. – buildsucceeded Oct 06 '16 at 13:57
