Answer 1

Angular 6 support Safari version >= 10. On windows system latest version of safari is 5 and on Mac it is 12 as of now(1st Aug 2019). If you are verifying on windows safari, it will not work. You need to check it on Mac machine.

You can check safari release history here

You can also try on Firefox browser instead of Safari. It can gives similar results.
