Realm DB compatibility issue between Swift SDK and React Native app #8703
Description
How frequently does the bug occur?
Always
Description
Description:
I've developed a React Native app that uses a Swift SDK, both of which rely on Realm DB. The following versions are in use:
iOS (SPM): https://github.com/realm/realm-swift.git, version 10.12.0
React Native: "realm": "^20.0.0"
Problem:
The app crashes when attempting to write an object in Realm.
One of our clients also uses this SDK in their React Native app, and they are encountering the following error:
Fatal error: 'try!' expression unexpectedly raised an error: Error Domain=io.realm Code=15 "History schema version not consistent" UserInfo={Error Name=IncompatibleSession, NSLocalizedDescription=History schema version not consistent, Error Code=15}
This issue only occurs in the React Native environment. We don't have exact version details for the client's environment.

Thread 1: EXC_BAD_ACCESS (code=1, address=0x0)Can you reproduce the bug?
Always
Reproduction Steps
Set up the React Native app:
Initialize a new React Native project.
npm install [email protected] --save
Integrate the Swift SDK:
Use Swift Package Manager to include the SDK:
.package(url: "https://github.com/realm/realm-swift.git", .upToNextMajor(from: "10.12.0")),
The SDK uses Realm Swift version 10.12.0.
Invoke the Swift SDK from React Native:
Use React Native's NativeModules to call methods from the Swift SDK.
Within the Swift SDK, attempt to write an object to Realm:
let realm = try! Realm()
try! realm.write {
realm.add(myObject)
}
Run the React Native app and trigger the Swift SDK method.
Expected Behavior:
The object should be written to the Realm database without any crashes or errors.
Actual Behavior:
The app crashes with the error mentioned above when the Swift SDK attempts to write to Realm.
