Play, pause and play from the beginning in swiftui (bug with playback reset)

[gerchicov-vg]

I have read your article:
#2189

In my particular case I have a button which works as "pause" and "restart play from the beginning" (depending on playback state).

According to your article I should switch between states:

• .paused
• .playing(.fromProgress(0, toProgress: 1, loopMode: .loop))

Instead of resetting to start it continues playback from the paused position.

I'm actually also confused why this doesn't reset progress -- it boils down to a LottieAnimationView.play(fromProgress: 0, toProgress: 1, loopMode: .loop) call, which is documented to cause playback to start from progress: 0 (not the current progress -- that would be fromProgress: nil).

The Main Thread rendering engine (which hasn't been modified in a long time) and the Core Animation rendering engine both behave this way. I agree the behavior is confusing and maybe incorrect, but changing it in a backwards-compatible way would be difficult.
