change the duration of animation and update the animation at runtime

[Rabicocoa]

I need a way to create a custom lottie animation, where I can change the duration of animation and update the animation at runtime. Basically, I want to build a loader using lottie to show the progress animation in case of any kind of downloading.

If you want to tie the progress of an animation to the progress of a download task, I'd suggest setting animationView.currentProgress = downloadTask.progress in your download task's progress handler. If you want to adjust the duration of your animation (e.g. make it play slower or faster) then you could configure animationView.animationSpeed.
