Error installing and running Realm iOS

Goals

Install Realm and be able to run the app

Expected Results

Realm installs and able to be used in the app.

Actual Results

Build fails and app comes with missing Realm constructor error.

Warning when realm installs

node-pre-gyp install --fallback-to-build

node-pre-gyp WARN Using request for node-pre-gyp https download.

Seems to install fine. React-native link realm produces no errors.

Have tried installing Realm in a brand new build and same issue. Funnily enough it runs fine on Android.

The build fails when running react-native run-ios.

** BUILD FAILED **

Version of Realm and Tooling

Realm JS SDK Version: v2.18.0 Node or React Native: Node v8.11.3 RN @0.57.1 Client OS & Version: OS Mojave 10.14

[Malikkhoja-zz]

Facing same issue on RN 0.61.2 and Realm 3.2.0. Any suggestions?

[reyn-nova]

@taylor-pringle I have facing this issue while using XCode 10, are you using XCode 10? If you using Xcode 10 then you need downgrade to previous XCode version because react-native doesn’t fully supporting XCode 10 yet.
