Hi, I noticed the README says:

The iOS implementation could not be tested yet. I appreciate any feedback.

Just wanted to provide some feedback that the plugin works on iOS. I've tested it on the Simulator as well as on iPhone and iPad devices. I got a small app published using this plugin.

Thanks a lot! 🍻
