Loading animations with source doesn't work in Release iOS builds

[Nezz]

Description

This PR added support for bundling Rive animations like images. However, this broke at some point for iOS release builds (possibly Expo 54).

Provide a Repro

1. Add a Rive animation to an Expo 54 project:

<Rive source={require('@/assets/animations/Test.riv')} autoplay fit={Fit.Contain} />

2. Add the following line to metro.config.js to ensure that riv files get bundled:

config.resolver.assetExts.push('riv');

3. Make a Release build for iOS

Development builds are not affected by this issue as they load the animations from your dev machine

Source .riv/.rev file

Issue is not related to a concrete file

Expected behavior

The animation should load

Actual behavior

The animation fails to load. On this line the plugin expects a URL like this:

file:///path/to/MyApp.app/assets/animation.riv

However, the actual URL is this:

file:///var/mobile/Containers/Data/Application/D96CE0CC-9CE0-445A-99DD-91578B1DCAAF/Library/Application%20Support/.expo-internal/ef6df2fd7a0eb9bae383f61feb81aa26.riv

@Nezz thanks much for the report, this should have been addressed in #328
See: 632240e

Should be in v9.3.4 and later.

What version are you on?!

[Nezz]

I'm on version 9.6.1. That didn't resolve it for me.

I believe that code isn't supposed to hit the "fallback to url for downloaded assets", but this is the URL Rive tries to load and it doesn't match the regex:

file:///var/mobile/Containers/Data/Application/D96CE0CC-9CE0-445A-99DD-91578B1DCAAF/Library/Application%20Support/.expo-internal/ef6df2fd7a0eb9bae383f61feb81aa26.riv

I wonder if this fixes it? #344 (which I just saw that you commented on)

[mfazekas]

@Nezz yes exactly that's expecting the files inside .app which is not the case.

#344 should address this
