Answer 1

I just had the same issue specifically with react-native-vector-icons using RN 0.61.4 and Xcode 11.2.1 while upgrading an app to > 0.6. What I ended up doing to get it to build was go to Build Phases -> [CP] Copy Pod Resources -> Deleted references to react-native-vector-icons fonts. Then rebuilt and everyone ran nicely. I did notice the fonts were already in the Resources folder on the project explorer on the left. I also commented out the # pod 'RNVectorIcons', :path => '../node_modules/react-native-vector-icons' line in the Podfile and ran pod install but not sure if the affected it or not. This is just a patch but hope it helps.

I checked all links from XCode errror and have not found any dublicate files.
