Hi @dsherida yes, you removed the native code, and there are additional steps you need to do to complete this, please refer to this section of the docs https://github.com/demchenkoalex/react-native-module-template#ios and for Android right under iOS. You can find it in the README right after this sentence If you didn't use js-only you are good to go. If you did, you need to unlink native code from the example. Basically, Xcode complaining because there is a leftover from native setup which was hard to remove because of a *.xcodeproj structure. Don't forget to remove native leftovers from Android, because it will complain too :) Let me know if that helps.

Wow thank you for the quick reply. I will be sure to follow those steps and report back once it works and then we can close this. Thank you so much!

Wohoo! That worked great thanks. Can't believe I overlooked that section of the docs. Cheers! 🍻
