## Checklist
- [X] I searched for existing GitHub issues
- [X] I updated all Cordova tooling to most recent version
- [X] I included all the necessary information above

Start by reproducing network.connection.type on an iPhone XR running iOS 13.2.2 with cordova-plugin-network-information 2.0.2, then inspect the plugin's iOS implementation. Done means the API reports WIFI or mobile data instead of unknown for the corresponding connection.
