I had the same problem today. I managed to get it working by:
react-native ejectreact-native linkAre you using
wix/react-native-navigation? If you are there will be 2getPackages()methods in yourMainApplication.java, do make sure both methods are returningnew RealmReactPackage().Use this
npm install realm@hermesWork’s for me.
from above 0.60 react native projects, auto link is not working either maintainers of the package has to code for auto linking project while doing npm install <package-name> itself. for make it work needs to manual link try drag and drop node module iOS project and add libRealmReact.a file to build phases. hope this will work
