undefined is not a function(evaluating '_iteratortypeof Symbol === "function"?Symbol.iterator:"@@iterator"')

Hello, looks like this is not related to calendars library

Hello @tautvilas I have the same problem mentioned above, I just added the example inside the project, my project uses React Navigation and Redux.

How is it not related to this library?
One of the first sentences in README.md is

The package is both Android and iOS compatible.

But library contains code that is not compatible with Android.

I saw this, which worked out smoothly.

I upgraded to 0.57.2 from 0.55.4 and the only thing that worked for me was to add babel-polyfill.

npm i --save-dev babel-polyfill

then in my index.js:

import 'babel-polyfill';

I did not try what @dungps suggested.
