[wendyliga]

this will let atlantis be used on projects with a minimum requirement of ios below 13.0

if project minimum ios are below 13.0

import Atlantis

if #available(iOS 13.0, *) {
   Atlantis.start()
}

for project with minimum ios 13.0 or more

import Atlantis
Atlantis.start()

Sorry, if you'd need Atlantis to work with below iOS 13, you can fork this repository and update it with your PR.

I suppose that it's reasonable to support iOS 13+ since iOS 12 or below it's really much out of date.

I gonna bump to iOS 14 soon too.
