SwiftUI UIViewRepresentable size issue

[drlukas6]

Hi!
I'm using Lottie with SwiftUI.
I implemented UIViewRepresentable similar to what is done in this article.
Basically in UIViewRepresentable I added the AnimationView as a subview and used Auto Layout to constraint it on all sides and returned that container view.

When using that Lottie view in a banner, or any other view that has an aspect ratio different then of the animation itself, the animation view size breaks

Which Version of Lottie are you using?

Lottie 3.4.1

Expected Behavior

• Lottie animation (white part with the content hidden behind the rectangle) should fill the whole view, not leave a green border left and right

NOTE: I set the green background to the container view to preview the issue better.

• The SwiftUI view should get the correct size, the one that fits the animation exactly and use that size for the view.

Actual Behavior

Animation JSON

N/A
