## Changelog

fix: dependency.platforms.ios.project is not allowed on RN 0.69

Pull Request resolved: https://github.com/facebook/flipper/pull/3860

Test Plan:
I don't know how to test my branch directly, but I did a simple change that can easily be tested with this method:

Start a fresh `react-native` 0.69 project:
```
npx react-native init flipperBugTest
```

Then install `react-native-flipper` package:
```
yarn add -D react-native-flipper
```

Navigate to `flipperBugTest/node_modules/react-native-flipper` and delete `react-native.config.js` file.

And start `react-native` metro:
```
react-native start
```
