Missing realm constructor react native ios but realm is linked

Keep getting the Missing Realm Constructor error and have tried everything from the Realm documentation on this common issue to relinking with rnpm link realm which tells me they're already linked. I've also tried linking in Xcode by adding in the libRealmReact.a file manually, but all to no avail.

For now, you can add this line in your Pod file:-

pod 'RealmJS', :path => '../node_modules/realm' pod 'GCDWebServer'

For me following steps worked, here version of realm npm played major role -

step1

npm install --save [email protected]

react-native link realm

step2 : Run(build) XCode project target named 'RealmReact'

step3 : Link binary with library for your project, add framework named 'libRealmReact.a'

That's all if the above steps didn't work, try to delete test target of RealmReact.xcodeproj

 your xcode project->Libraries->RealmReact.xcproject->Test target for this linked project

After a few long hours of debugging and going through GitHub issue articles (and posting one of my own), I found this article where the solution is to set the Realm variable as null for load, but to define the variable in the constructor as so: 

const Realm = null;
constructor() {
    if (Realm === null) { Realm = require('realm'); };
}

The issue is that there is some sort of timing issue where Realm doesn't load before the view itself instantiates.
