But this way I couldn't test my https website even in an IOS9 machine, how should I fix this if I want to use the latest version of webpack-dev-server?

@MarvinXu you can't use the latest version if you need to support browsers that don't support const and let. iOS 9 was released in 2015 and oldIE support was killed in 2016. As the README states, you'll have to use v2.7.1 if you want to support platforms that old.
