App crash EXC_BAD_ACCESS if Lottie is part of dependent package and is used in parent project as well

[ikaransingla]

Lottie was working fine in my project after updating AnimationView to LottieAnimationView even in XIBs too.
It's been crashing since the time I have integrated an SPM package which also has Lottie as the dependency.
Both the project and the package has the same version of Lottie (4.0.1). Tried downgrading the version to 3.5.0 as well but it's still crashing.

Which Version of Lottie are you using?

3.5.0, 4.1.0

Expected Behavior

The animation should work fine.

Actual Behavior

Facing crash at the time of animation assignment.

The animation is working fine inside the added package though.

Animation JSON

Facing this crash for all json files. Attaching a sample one for reference

Can you share a sample project demonstrating this issue?

[ikaransingla]

I've created a sample project which also have the same issue.

LottieTest.zip

The package used in this project is at https://github.com/ikaransingla/LottiePackage

The code used to build the framework is
LottiePackageTest.zip

I think having multiple copies of the same library loaded / compiled separately is not very well-supported. I know storyboards work by expecting there to be a unique Lottie.LottieAnimationView type, which isn't the case in this project setup. Since this seems to be an SPM / linker / Xcode / storyboard problem and not a bug with Lottie itself I've converted this from an issue to a discussion.

The fix here would be to update the package setup / dependency graph to only have a single copy of the Lottie module. If that's not feasible another workaround could be to avoid using Lottie via storyboards -- initializing your LottieAnimationView via code instead probably wouldn't have this EXC_BAD_ACCESS issue.

These sorts of warnings are relevant here -- multiple copies of the Lottie.LottieAnimationView symbol are present so runtime behavior is undefined

One of the two will be used. Which one is undefined.

@ikaransingla
I'm facing this issue on v4.4.3, did you able to fix that issue on your end?
