Description

Upgraded rive-react-native to 6.2.0 from 3.0.41 and now it's crashing the entire app all the time.

Error message in Xcode is:
rive_react_native/RiveReactNativeView.swift:225: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value

Expected behavior

I'd expect it not to start crashing when updating the package.

Screenshots

Device & Versions (please complete the following information)

• Device: iOS simulator iPhone SE (3rd generation)
• OS: iOS 17.2
• NPM Version: 10.1.0

Additional context

• I tried upgrading the Rive app to latest version and re-exporting the riv file, but it didn't help.
• Also removed and updated node_modules and pods a few times as well as tried rebuilding the iOS app.

This PR seems to fix the issue for me: #206

Hi Waltari, thanks for verifying. Would you happen to have a reproducible example project you can share with us? I'm not able to verify the issue on my side.

The same with the linked issue. But in the meantime we can get that linked PR merged as it seems to solve multiple issues

The above PR is merged. I'm closing this issue, but please reopen it if it's not fixed.
