+1, same problem on 0.56.

TypeError: undefined is not an object (evaluating 'e.default')

at

const { width, height } = Dimensions.get('window');

But Dimensions is imported

[mmamoyco]

@kufufu9 how do you find error cause?

[patrickkempff]

How does your import statement look?

[mmamoyco]

@patrickkempff I dont really know where to find the cause of problem, my index.js

import { AppRegistry } from 'react-native';
import App from './App';

AppRegistry.registerComponent('SCards', () => App);

[kufufu9]

@godofmadness I was found the cause on https://sentry.io/

This also affects Android release builds (debug is ok)

Do you use react-navigation? This helped for me: aksonov/react-native-router-flux#3124 (comment)
