This looks like an Apple breaking change (since `SCNAnimation` is new)
but we now have:
> typedef void (^SCNAnimationEventBlock)(id<SCNAnimation> animation, id animatedObject, BOOL playingBackward);
bound as
> delegate void SCNAnimationEventHandler (CAAnimation animation, NSObject animatedObject, bool playingBackward);
and `CAAnimation` conforms to `SCNAnimation` but *only* the later is
available on watchOS. The delegate is only updated (since it's new)
on our watchOS profile.
