Realm-js: Realm-JS and RealmSwift integration in a React Native application doesn't work when compiled with Xcode 9.

Created on 27 Oct 2017 · 32Comments · Source: realm/realm-js

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.

Hi @rajeshdongre I was having this issue you have described and have managed to fix it in my project. I am using RealmSwift 3.20.0 and RealmJS 3.4.2. RealmJS as of 3.4.0 includes a podspec which allows you to do a pod install instead of manually linking. I assume this means that the core issue causing this error is a linking issue.

@rajeshdongre Just to absolutely sure: you only see this crash with Xcode 9? Can you provide us with a sample app with can reproduce the crash? You are welcome to send it privately to [email protected].

kneth on 27 Oct 2017

@kneth Thank you for your quick response. Answer to your first question is Yes. We were using above mentioned Realm-JS SDK and RealmSwift versions for our brownfield application with Xcode 8. I will share a sample application which will resemble our existing application over [email protected].

rajeshdongre on 27 Oct 2017

@kneth I tried to email you Sample application, which explains the scenario that we are facing in our app. But email got rejected by [email protected]. Finally I uploaded the same source on Github repository. Please have a look at https://github.com/rajeshdongre/RNRealmSample repo. Sample app doesn’t include node_modules, so it will need ‘npm install’ to be executed before running the application using Xcode 8/9.
Please let me know there are in any discrepancies in the shared sample.

rajeshdongre on 28 Oct 2017

Sorry to hear that you had issues email us. What was the error message?

I believe we have seen issues with Xcode 9 and we need to investigate a bit more.

kneth on 30 Oct 2017

@kneth Once again thank you for your quick response. When I tried to send an email with Sample app attached, it gave me below error:
`mx.google.com rejected your message to the following email addresses:

@rajeshdongre Looks like Google is blocking emails if you attached zip files. I better stop asking people to send us files but ask them to provide a link to the file :smile:

@kneth Were you able to replicate the issue? Let me know if you need help in replicating the same.

msimons0 on 6 Nov 2017

Hello @kneth and @bmunkholm, We have a project depending on getting a fix to this issue. Our due date is mid December. Can you provide status update on the fix or how we can move forward on this issue? Your urgent resonse is greatly appreciated.

DaleKni on 23 Nov 2017

@DaleKni We are actively working on it. You can follow the progress in PR #1483.

kneth on 23 Nov 2017

Version 2.1.0 tries to improve the situation with Xcode 9. Please upgrade.

kneth on 18 Dec 2017

🎉1

@kneth and @bmunkholm, We are seeing the same issue on version 2.1.0 as well. Can you please confirm?

msimons0 on 20 Dec 2017

@msimons0 Thanks for the update. Is it the mixture of Realm JS and Realm Swift which is causing the issue? Do you have a simple project to share?

kneth on 21 Dec 2017

@kneth Yes that's possible.

I'm able to replicate the exact same issue with @rajeshdongre's app at https://github.com/rajeshdongre/RNRealmSample

msimons0 on 22 Dec 2017

@kneth Any updates?

msimons0 on 7 Jan 2018

👍1

@msimons0 No progress to report but one issue could be that Realm JS 1.3.x and Realm Swift 2.7.x are using a different Realm Core version. You might be better off with Realm Swift 2.8, 2.9 or 2.10.

kneth on 8 Jan 2018

@kneth As suggested by you, we tried using updated version of Realm Swift but with no success. We even used updated version of Realm JS. We have updated the old sample application shared with you (https://github.com/rajeshdongre/RNRealmSample).
As mentioned in your comments we made sure that sample application should use same Realm Core version for Realm JS and Realm Swift libraries.
Above given sample application uses Realm JS 2.0.0 (Realm Core Version 4.0.2) and Realm Swift (Realm Core Version 4.0.2). Hope this sample application will help you to reproduce the scenario.

rajeshdongre on 11 Jan 2018

@kneth I have run into the same issue while integration Realm js and Realm swift , have you guys found any solution?

kbs95 on 17 Mar 2018

@kbs95 To be honest, we haven't had time to investigate a solution.

This is the output I get, in case it helps any.

@thatjuan It looks like a crash when doing a query. Do you by any chance do the query on another thread that where the Realm was opened?

I'm also experiencing same problem but I'm using Realm for objective-C

I updated to latest with the same Realm core version 5.4.0

Realm JS Version: 2.4.0
Realm Cocoa Version: 3.3.0

But it yields same error.

Tried latest version objc dynamic/static realm framework with react native realm.

Using dynamic: the same error that @lynrose10 posted will be thrown;
Using static: the "multiple implementation" error will be thrown.

And I found the error had nothing to do with the objc code, just related to framework itself. You don't need to write any native objc code, just add the dynamic framework, then the app crashed.

@rajeshdongre did you manage to solve this issue? If so, could you share how do you guys configure the project to use both react native and native with realm? I am able to do this in Android, but can't figure it out on iOS.

I'm hitting the same issue on iOS when trying to share realms between React Native and Native. Works perfect on the Android side but on iOS I hit the following...

src/realm/table.hpp:1774: [realm-core-5.19.1] Assertion failed: dynamic_cast<Parent*>(parent)

Note: even if I try to run separate Realms (e.g. default.realm on iOS and someOtherRealm.realm on RN) I still hit the above error.

I'm using Xcode 10.2.1, React Native 0.59.9, RealmJS 2.28.0 and RealmCocoa 3.16.2 (both appear to use realm-core 5.19.1 so don't think that's the issue).

Is sharing realms between React Native and Native something that _should_ work (and is supported)?

@mrbrentkelly We haven't actively worked on it so your mileage may vary. I think the hard part is to get the package dependency on iOS/Xcode right. Do you have a complete stack trace from the assertion?

@kneth sure thing...

It is similar to #884.

@kneth is there any progress on the issue? Could you please suggest any working workarounds? Any method mentioned on related threads fails.

dsemenov on 27 Jul 2019

@dsemenov Just returned from vacation so no progress to report. It comes up regularly, and it is a useful feature. I hope that we will be able to return to it later this year but I can't promise it.

Fixed by suppoting Podspec (from Realm JavaScript v3.4.0).
