same issue as you

Please share a sample project that reproduces this error

to_keyboard.json

When loading the lottie's JSON above, it will block the main thread of app more than ten seconds.

sample code:
let view = LottieAnimationView(name: "to_keyboard")
view.play()

I tested this locally and I see that the performance issue happens in a debug build, but not in a release build.

That suggests this is some sort of pathological performance issue in the Swift compiler (e.g. the compiler not generating properly optimized code in debug, or something) rather than a problem in Lottie itself.

If you have repro steps for this that show performances issues in a release build as well, feel free to re-open the issue.
