Interface Builder Layer Transitions

I'm trying to use Core Animation to make a "push" transition for
subviews inside a window with previous and next buttons.

I tried setting the transition effects in IB for each view's "Order
In" transition, as well as setting the containing view's "Subviews"
transition, to no avail.

[subviewArea addSubview:view] causes an immediate transition, while
[[subviewArea animator] addSubview:view] causes a fade transition, not
the transition I was expecting

When I ask [[view layer] animationForKey:NSViewAnimationFadeInEffect]
in gdb it returns nil. Not sure if this is related.

Here is the test project I'm working on:

I searched in the archive and didn't turn up anything. Any help would
be greatly appreciated!
