Using lottie-ios in framework that is imported in app which also depends on lottie-ios crashes on setValueProvider

[Antonio210696]

Hello! Our company produces an SDK that is then shipped inside customers' applications. We show some UI that uses Lottie. Up to now, we used to have lottie-ios imported as a Swift package with version 3.5.0. We ship the SDK as a framework binary via Cocoapod. A customer of ours also has a dependency to Lottie (via Cocoapods) and they are using version 3.0.0. They reported us a strange crash that happens in a portion of their code which does not even call our SDK. They simply setup an animation and use setValueProvider to change the color of the animation, like this:

    @IBOutlet weak var animationLoaderView: UIView!
    private let animationView = LottieAnimationView(name: "loader_firma")
    
    private func setupAnimationView() {
        animationView.frame = animationLoaderView.bounds
        let fillKeypath = AnimationKeypath(keypath: "**.Stroke 1.Color")
        let redValueProvider = ColorValueProvider(UIColor.blue.lottieColorValue)
        animationView.setValueProvider(redValueProvider, keypath: fillKeypath)
        animationLoaderView.addSubview(animationView)
        animationView.animationSpeed = 0.9
    }

setupAnimationView is then called at viewDidLoad inside the ViewController.
We managed to reproduce the crash, below are the screenshots of the stack trace. Another important thing is that at launch in the console, both we and the integrator see these warnings about classes being implemented in two places.

We have tried updating our Lottie version and the Lottie version of the integrator. After many attempts, the only solution that works is to switch in our SDK from using lottie-ios to using lottie-spm, which is the precompiled version. This makes the warnings above disappear and the integrator app works as expected.

It seems that having duplicated symbols is an issue for Lottie, but I don't understand why, as there are other libraries which spawn those warning and non is creating issues right now.

Using lottie-spm is an improvement for us, so it was ok to switch, but we would like to have a better understanding of the root cause of this crash. If anyone could give us any clue, that would be much appreciated.

Thank you in advance 🙏

Which Version of Lottie are you using?

Lottie 3.5.0 and above from lottie-ios

Expected Behavior

The app should run normally, playing the animation with the correct color

Actual Behavior

The app crashes as soon as LottieAnimationView.setValueProvider is called.
