> There are libraries similar to Lottie, such as Marcus Eckert’s Squall and Facebook’s Keyframes, but our goals are slightly different. Facebook picked a small set of After Effects features to support, since they were focusing mainly on reactions, but we want to support as many as possible.

Interesting. Supporting more AE features is a good plus. Can you talk more about the other goals that are different?

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.

For Lottie, they are offloaded to native Core Animation. :)
