Library Version

1.0.0

React Native Version

0.81.5

React Version

19.1.0

Expo Version

54.0.32

Minimal Reproduction

1. npx create-expo-app voltra-repro --template blank
2. install voltra@1.0.0
3. Add to app.json:

• "ios": { "bundleIdentifier": "com.example.voltrarepro" }
• "plugins": [["voltra", {"groupIdentifier": "group.com.example.voltrarepro"}]]

4. Run: npx expo config --type introspect
5. Error: ENOENT .../ios/voltrareproLiveActivity/Info.plist

Additional Information (Optional)

Root cause: plugin/src/features/ios/plist/index.ts calls fs.readFileSync() without checking if the file exists. During introspect (before prebuild), the ios/ folder doesn't exist yet.

This breaks EAS builds since EAS runs introspect before prebuild.

Verified on both 1.0.0 and 1.1.2 (latest).

Fix: Add fs.existsSync(filePath) check before reading.
