Animation JSON

Lottie Animation Link
doubleSpinner.json

Code

Since our main app is based on SwiftUI, we are using a wrapper around LottieAnimationView. However, we have also tried using the SwiftUI version of LottieView, and we have attempted the solutions suggested in other issues, including changing the RenderingEngine. Unfortunately, the problem persists.

Thank you for always providing such a great library.

import Lottie
import SwiftUI

struct CustomLottieView: UIViewRepresentable {
var animationFileName: String
let loopMode: LottieLoopMode

func updateUIView(_ uiView: UIView, context: Context) {}

func makeUIView(context: Context) -> UIView {
    let view = UIView(frame: .zero)

    let configuration = LottieConfiguration(renderingEngine: .mainThread)
    let animationView = LottieAnimationView(name: animationFileName, configuration: configuration)

    animationView.loopMode = loopMode
    animationView.contentMode = .scaleAspectFill
    animationView.translatesAutoresizingMaskIntoConstraints = false

    view.addSubview(animationView)

    NSLayoutConstraint.activate([
        animationView.widthAnchor.constraint(equalTo: view.widthAnchor),
        animationView.heightAnchor.constraint(equalTo: view.heightAnchor),
        animationView.centerXAnchor.constraint(equalTo: view.centerXAnchor),
        animationView.centerYAnchor.constraint(equalTo: view.centerYAnchor)
    ])

    animationView.play()

    return view
}

}

#if DEBUG
#Preview {
CustomLottieView(animationFileName: "doubleSpinner",
loopMode: .loop)
.frame(width: 200, height: 200)
}
#endif

Additionally, the same issue occurs with .lottie file formats.

Your Lottie JSON animation file has a problem; it’s not an issue with the Lottie SDK.
