How should I change the changelog?

[gvarandas]

So, I was just testing your PR and it seems like we're missing a few pieces to make sure things work 100% as we'd expect:

• The fixture app is set up using an old version of react-native-test-app, so we should probably update it (^3.4.3 seems like the latest)
  • With that change some of the app's setup is also changed (Gradle files, react-native-config.json, etc), so we might need to revamp it as well
• Running pod install relies on having a global version of cocoapods installed, which isn't great, so we should probably add a Gemfile to the fixture folder as well that installs it.

I've applied the changes to this branch (fixture_72), if you want to take a look and test it. Might be easy enough to add it to your PR so we can get it merged sooner than later 🙇

Hey @gvarandas, I took a look and it worked perfectly for me.
