Answer 1

Following the migration stated in their changelog you should add es2015.iterable as a lib inside your tsconfig.json:

{
  ...,
  "compilerOptions" : {
     ...,
     "lib": ["es6", "dom", "es2015.iterable"]
   }
}

I tried the accepted answer for this question but it didn't work in my case.

In my case I added below line in my main.ts

///<reference path="./../typings/globals/core-js/index.d.ts"/>

which fixed the issue, hope this helps someone.
