Description
We have an iOS app that was initially written in Swift/SwiftUI and we are slowly adding React Native components. The app has a working Realm DB on the swift side and we were looking to create a separate Realm instance on RN/JS side. As the first steps, we ran
- yarn add @realm/react realm
- pod install
We haven't created the Realm instance on JS side yet and the app crashes on launch. It seems whenever the original Realm DB is queried/used, the app crashes. (Stacktrace of one of the crashes are attached; "Access to invalidated Results objects." is the message of exception.)
One data point: I looked into the realm-JS source (RealmReact.mm) because I suspected that some initialization code on the JS side is changing the underlying state of RealmSwift/RealmCore since we haven't even instantiated any Realm DB on the JS side yet. Returning early in setBridge without calling realm_jsi_init does seem to address the crash, which agrees with my hypothesis about Realm-JS initialization stepping on the internal state of Realm somehow.
The question is, does Realm support the coexistence of RealmJS and RealmSwift? Or are we doing something that's not officially supported? We might have to look into alternative solutions if this use case is not supported and any response would be appreciated!
