I can! I built out the iOS side of the project. Aside from supporting as many after effects features as possible we wanted push what could be done with animation. One example in the current version is using exported after effects files as animated transitions between view controllers. In the future we hope to support more programmatic and interactive uses of animations built in after effects.

So after effects is controlling the shared element transitions?

The animations built from After Effects are programmatically altered to build the UIViewController transition.
