Does it? The likelihood is that the animation is performed using a regular interval, but the position is modified according to the S- curve function. With only 7 steps of animation, it's probable that you are just not noticing the easing in and out, which doesn't deviate that much from the linear.


Actually, looking at NSAnimation this is probably wrong, since this is how you get notified of where you should be, it should include the effects of the curve. Do try a longer time though and see if it makes the curve more obvious, 7 samples may be too few to see it.
