Realm-js: [v10.0.0-beta.12] [iOS] ld: symbol(s) not found for architecture x86_64

[ioveracker]

Goals

Build a React Native app using v10.0.0-beta.12.

Expected Results

iOS app builds and runs successfully.

Actual Results

Build fails with linker errors (undefined symbols) in libRealmJS.a. I have tried cleaning Xcode build directories, removing node_modules/, removing ios/Pods/, and reinstalling.

_Note: Android builds and runs fine, so this is only an iOS issue._

Steps to Reproduce

Repro case here: https://github.com/ioveracker/mongodb-realm-react-native-playground/tree/realm-v10.0.0-beta.12

1. Install packages with yarn.
2. Install iOS dependencies with cd ios && pod install (or use yarn setup:ios if you have rbenv and want to lock in the same ruby / bundler / cocoapods versions).
3. Attempt to build and run the iOS app with yarn ios.

Same issue for me

[kneth]

It is clearly a bug at our end.

Until we get a fix out, you can try to change librealm-ios.a to librealm-sync-ios.a in https://github.com/realm/realm-js/blob/v10/RealmJS.podspec#L94.

The fix has been merged and we will release it soon.

[mxia]

Any timeline on when beta13 will be released?

[euZebe]

@mxia it has been released today.

Using [email protected] and Xcode 10.1.

[kneth]

@praveen-wal Thank you for reporting.

[kneth]

@praveen-wal We build for Xcode 11 and not Xcode 10. Please consider to upgrade :-)

[praveen-wal]

Sure @kneth. For now, I'm using [email protected], I am getting a different issue. This might not be related to the above issue.
I'm getting this error https://github.com/realm/realm-js/issues/3105.

[douglassthomas]

@kneth can you please make an update available for Xcode 10?
i also face the problem like this:

realm::util::(anonymous namespace)::ensure_reclaimer_thread_runs() in librealm-sync-ios.a(file_mapper.o)

realm::util::network::SecureTransportErrorCategory::message(int) const in librealm-sync-ios.a(network_ssl.o)

realm::util::network::ssl::Stream::verify_peer() in librealm-sync-ios.a(network_ssl.o)

[kneth]

@douglassthomas

can you please make an update available for Xcode 10?

Xcode 10 isn't supported by Apple.
