`LottieView` caused builds to fail

[BenShutt]

LottieView (previously named Lottie) is defined in this package but wrapped in a #canImport statement.

I managed to get the app running from a simulator using LottieView from this framework, but the build seemed to fail.

I'm not sure the way we are conditionally importing Lottie is correct?

Think Lottie may support SwiftUI directly now? airbnb/lottie-ios#2189
