What is the difference between e.NewElement and Element?
Also iOS is setting up a new page inside OnElementChanged here: https://developer.xamarin.com/guides/xamarin-forms/custom-renderer/contentpage/, but I've seen many examples where ViewDidLoad is used for such purpose. Here's an example: https://blog.xamarin.com/customize-your-xamarin-forms-app-with-pages-for-each-platform/ When do we use which?
