Importing Realm returns the error "Undefined is not a constructor (evaluating 'new XMLHttpRequest')"

Goals

Import Realm into a React Native project.

Expected Results

I should be able to import Realm and run the project in iOS with crashing.

Actual Results

The app crashes in release mode completely. The app crashes in debug mode if not using Chrome Debugger and I get this error on the screen: Undefined is not a constructor (evaluating 'new XMLHttpRequest')

I get this repeating error in the console "Must first create RPC session with a valid host".

Steps to Reproduce

I’m trying to import Realm into my React Native project and run in iOS. I’ve installed the npm and linked it. It crashes when I add the following line:

import Realm from 'realm';

By the way, something similar happens on Android. This message is iOS only but here is the error for both platforms :

• ios crash :

undefined is not a constructor (evaluating 'new XMLHttpRequest()') makeRequest - rpc.js:204:22

• android crash :

Can't find variable : Symbol <unknown> - constants.js:30:24
