Hi,
We are writing a brownfield React Native application wherein we need realm-js as well as RealmSwift integration. It worked till date with realm-js version 1.3.1 and RealmSwift version 2.7.0. But when we are trying to migrate to Xcode 9, we are getting below mentioned runtime error logs. If you could help us on the same.

Error logs
