Lottie 4.3.2

Lottie 4.3.2 redesigns the LottiePlaybackMode playback APIs that were introduced in Lottie 4.3.0.

Before

// Loop from 0.5 to 1.0
LottieView(animation: myAnimation)
  .play(.fromProgress(0.5, toProgress: 1.0, loopMode: .loop))

// Pause at the halfway point of the animation
LottieView(animation: myAnimation)
  .play(.progress(0.5))

After

// Loop from 0.5 to 1.0
LottieView(animation: myAnimation)
  .playing(.fromProgress(0.5, toProgress: 1.0, loopMode: .loop))

// Pause at the halfway point of the animation
LottieView(animation: myAnimation)
  .paused(at: .progress(0.5))
