I started having this error when I uncommented the following lines so that my project could be compatible with IE9, 10 and 11. Located in `polyfills.ts` `import 'core-js/es6/symbol';` `import 'core-js/es6/object';`...

I solved the issue by swaping to sweetalert 2. Im not sure if its developed by the same team (so im sorry for the propaganda if not). Hope it can...
