Screenshots and app previews for new devices now supported.

You can now upload screenshots and app previews for the new iPhone XS Max with your next version update or when your app has an editable status. These assets will be automatically resized for iPhone X and later. You can also upload screenshots for Apple Watch Series 4. Read the updated Human Interface Guidelines, download the latest version of Xcode 10, and use Simulator to test your app and create these assets. Learn about uploading screenshots and app previews.

Starting March 2019, all new apps and app updates for iPhone, including universal apps, will require iPhone XS Max screenshots. They must also be built with the new iOS 12 SDK and support the latest devices. All new apps and app updates for Apple Watch will need to be built with the watchOS 5 SDK and support Apple Watch Series 4.
