Desired functionality.

The app should be visible on iphone and mac safari but it's not working on the smaller device which is iphone 4s. It's working fine on iphone 5 and above.

Different browsers might need different polyfills. Please have a look at https://angular.io/guide/browser-support for the supported browsers. From that error message it seems your browser doesn't support iterables perhaps. Also have a look at src/polyfills.ts for instructions on how to use polyfills there.

Take a look at polyfills.ts file. In my case uncommenting the following solved the problem:

import 'core-js/es6/object';
import 'core-js/es6/string';
import 'core-js/es6/array';

I am getting the following error on Safari only on using google drive upload

[object Object]
runTask (polyfills.bundle.js:11161)
invokeTask (polyfills.bundle.js:111464)
invoke (polyfills.bundle.js:111453)
timer (polyfills.bundle.js:13005)

I have uncommented the imports in polyfills.ts already
Also added:
import 'intl';
import 'intl/locale-data/jsonp/en';

Kindly help me out here.
